For example, the following code -moves the value stored under key1 to key2. -<pre> - std::string value; - leveldb::Status s = db->Get(leveldb::ReadOptions(), key1, &value); - if (s.ok()) s = db->Put(leveldb::WriteOptions(), key2, value); - if (s.ok()) s = db->Delete(leveldb::WriteOptions(), key1); -</pre> - -<h1>Atomic Updates</h1> -<p> -Note that if the process dies after the Put of key2 but before the -delete of key1, the same value may be left stored under multiple keys. -Such problems can be avoided by using the <code>WriteBatch</code> class to -atomically apply a set of updates: -<p> -<pre> - #include "leveldb/write_batch.h" - ... - std::string value; - leveldb::Status s = db->Get(leveldb::ReadOptions(), key1, &value); - if (s.ok()) { - leveldb::WriteBatch batch; - batch.Delete(key1); - batch.Put(key2, value); - s = db->Write(leveldb::WriteOptions(), &batch); - } -</pre> -The <code>WriteBatch</code> holds a sequence of edits to be made to the database, -and these edits within the batch are applied in order.

The transfer from operating system memory to the underlying -persistent storage happens asynchronously. The <code>sync</code> flag -can be turned on for a particular write to make the write operation -not return until the data being written has been pushed all the way to -persistent storage. (On Posix systems, this is implemented by calling -either <code>fsync(...)</code> or <code>fdatasync(...)</code> or -<code>msync(..., MS_SYNC)</code> before the write operation returns.) -<pre> - leveldb::WriteOptions write_options; - write_options.sync = true; - db->Put(write_options, ...); -</pre> -Asynchronous writes are often more than a thousand times as fast as -synchronous writes. The downside of asynchronous writes is that a -crash of the machine may cause the last few updates to be lost. Note -that a crash of just the writing process (i.e., not a reboot) will not -cause any loss since even when <code>sync</code> is false, an update -is pushed from the process memory into the operating system before it -is considered done. - -<p> -Asynchronous writes can often be used safely. For example, when -loading a large amount of data into the database you can handle lost -updates by restarting the bulk load after a crash. A hybrid scheme is -also possible where every Nth write is synchronous, and in the event -of a crash, the bulk load is restarted just after the last synchronous -write finished by the previous run. (The synchronous write can update -a marker that describes where to restart on a crash.) - -<p> -<code>WriteBatch</code> provides an alternative to asynchronous writes. -Multiple updates may be placed in the same <code>WriteBatch</code> and -applied together using a synchronous write (i.e., -<code>write_options.sync</code> is set to true). The extra cost of -the synchronous write will be amortized across all of the writes in -the batch. - -<p> -<h1>Concurrency</h1> -<p> -A database may only be opened by one process at a time. -The <code>leveldb</code> implementation acquires a lock from the -operating system to prevent misuse. Within a single process, the -same <code>leveldb::DB</code> object may be safely shared by multiple -concurrent threads. I.e., different threads may write into or fetch -iterators or call <code>Get</code> on the same database without any -external synchronization (the leveldb implementation will -automatically do the required synchronization). However other objects -(like Iterator and WriteBatch) may require external synchronization. -If two threads share such an object, they must protect access to it -using their own locking protocol. More details are available in -the public header files. -<p> -<h1>Iteration</h1> -<p> -The following example demonstrates how to print all key,value pairs -in a database. -<p> -<pre> - leveldb::Iterator* it = db->NewIterator(leveldb::ReadOptions()); - for (it->SeekToFirst(); it->Valid(); it->Next()) { - cout << it->key().ToString() << ": " << it->value().ToString() << endl; - } - assert(it->status().ok()); // Check for any errors found during the scan - delete it; -</pre> -The following variation shows how to process just the keys in the -range <code>[start,limit)</code>: -<p> -<pre> - for (it->Seek(start); - it->Valid() && it->key().ToString() < limit; - it->Next()) { - ... - } -</pre> -You can also process entries in reverse order. (Caveat: reverse -iteration may be somewhat slower than forward iteration.) -<p> -<pre> - for (it->SeekToLast(); it->Valid(); it->Prev()) { - ... - } -</pre> -<h1>Snapshots</h1> -<p> -Snapshots provide consistent read-only views over the entire state of -the key-value store. <code>ReadOptions::snapshot</code> may be non-NULL to indicate -that a read should operate on a particular version of the DB state. -If <code>ReadOptions::snapshot</code> is NULL, the read will operate on an -implicit snapshot of the current state. -<p> -Snapshots are created by the DB::GetSnapshot() method: -<p> -<pre> - leveldb::ReadOptions options; - options.snapshot = db->GetSnapshot(); - ... apply some updates to db ... - leveldb::Iterator* iter = db->NewIterator(options); - ... read using iter to view the state when the snapshot was created ... - delete iter; - db->ReleaseSnapshot(options.snapshot); -</pre> -Note that when a snapshot is no longer needed, it should be released -using the DB::ReleaseSnapshot interface. This allows the -implementation to get rid of state that was being maintained just to -support reading as of that snapshot. -<h1>Slice</h1> -<p> -The return value of the <code>it->key()</code> and <code>it->value()</code> calls above -are instances of the <code>leveldb::Slice</code> type. <code>Slice</code> is a simple -structure that contains a length and a pointer to an external byte -array. Returning a <code>Slice</code> is a cheaper alternative to returning a -<code>std::string</code> since we do not need to copy potentially large keys and -values. In addition, <code>leveldb</code> methods do not return null-terminated -C-style strings since <code>leveldb</code> keys and values are allowed to -contain '\0' bytes. -<p> -C++ strings and null-terminated C-style strings can be easily converted -to a Slice: -<p> -<pre> - leveldb::Slice s1 = "hello"; - - std::string str("world"); - leveldb::Slice s2 = str; -</pre> -A Slice can be easily converted back to a C++ string: -<pre> - std::string str = s1.ToString(); - assert(str == std::string("hello")); -</pre> -Be careful when using Slices since it is up to the caller to ensure that -the external byte array into which the Slice points remains live while -the Slice is in use. For example, the following is buggy: -<p> -<pre> - leveldb::Slice slice; - if (...) { - std::string str = ...; - slice = str; - } - Use(slice); -</pre> -When the <code>if</code> statement goes out of scope, <code>str</code> will be destroyed and the -backing storage for <code>slice</code> will disappear. -<p> -<h1>Comparators</h1> -<p> -The preceding examples used the default ordering function for key, -which orders bytes lexicographically. You can however supply a custom -comparator when opening a database. For example, suppose each -database key consists of two numbers and we should sort by the first -number, breaking ties by the second number. First, define a proper -subclass of <code>leveldb::Comparator</code> that expresses these rules: -<p> -<pre> - class TwoPartComparator : public leveldb::Comparator { - public: - // Three-way comparison function: - // if a < b: negative result - // if a > b: positive result - // else: zero result - int Compare(const leveldb::Slice& a, const leveldb::Slice& b) const { - int a1, a2, b1, b2; - ParseKey(a, &a1, &a2); - ParseKey(b, &b1, &b2); - if (a1 < b1) return -1; - if (a1 > b1) return +1; - if (a2 < b2) return -1; - if (a2 > b2) return +1; - return 0; - } - - // Ignore the following methods for now: - const char* Name() const { return "TwoPartComparator"; } - void FindShortestSeparator(std::string*, const leveldb::Slice&) const { } - void FindShortSuccessor(std::string*) const { } - }; -</pre> -Now create a database using this custom comparator: -<p> -<pre> - TwoPartComparator cmp; - leveldb::DB* db; - leveldb::Options options; - options.create_if_missing = true; - options.comparator = &cmp; - leveldb::Status status = leveldb::DB::Open(options, "/tmp/testdb", &db); - ... -</pre> -<h2>Backwards compatibility</h2> -<p> -The result of the comparator's <code>Name</code> method is attached to the -database when it is created, and is checked on every subsequent -database open. If the name changes, the <code>leveldb::DB::Open</code> call will -fail. Therefore, change the name if and only if the new key format -and comparison function are incompatible with existing databases, and -it is ok to discard the contents of all existing databases. -<p> -You can however still gradually evolve your key format over time with -a little bit of pre-planning.

Keys and values are +arbitrary byte arrays. The keys are ordered within the key value store +according to a user-specified comparator function. + +## Opening A Database + +A leveldb database has a name which corresponds to a file system directory. All +of the contents of database are stored in this directory. The following example +shows how to open a database, creating it if necessary: + +```c++ +#include <cassert> +#include "leveldb/db.h" + +leveldb::DB* db; +leveldb::Options options; +options.create_if_missing = true; +leveldb::Status status = leveldb::DB::Open(options, "/tmp/testdb", &db); +assert(status.ok()); +... +``` + +If you want to raise an error if the database already exists, add the following +line before the `leveldb::DB::Open` call: + +```c++ +options.error_if_exists = true; +``` + +## Status + +You may have noticed the `leveldb::Status` type above. Values of this type are +returned by most functions in leveldb that may encounter an error. You can check +if such a result is ok, and also print an associated error message: + +```c++ +leveldb::Status s = ...; +if (!s.ok()) cerr << s.ToString() << endl; +``` + +## Closing A Database + +When you are done with a database, just delete the database object. Example: + +```c++ +... open the db as described above ... +... do something with db ... +delete db; +``` + +## Reads And Writes + +The database provides Put, Delete, and Get methods to modify/query the database. +For example, the following code moves the value stored under key1 to key2. + +```c++ +std::string value; +leveldb::Status s = db->Get(leveldb::ReadOptions(), key1, &value); +if (s.ok()) s = db->Put(leveldb::WriteOptions(), key2, value); +if (s.ok()) s = db->Delete(leveldb::WriteOptions(), key1); +``` + +## Atomic Updates + +Note that if the process dies after the Put of key2 but before the delete of +key1, the same value may be left stored under multiple keys. Such problems can +be avoided by using the `WriteBatch` class to atomically apply a set of updates: + +```c++ +#include "leveldb/write_batch.h" +... +std::string value; +leveldb::Status s = db->Get(leveldb::ReadOptions(), key1, &value); +if (s.ok()) { + leveldb::WriteBatch batch; + batch.Delete(key1); + batch.Put(key2, value); + s = db->Write(leveldb::WriteOptions(), &batch); +} +``` + +The `WriteBatch` holds a sequence of edits to be made to the database, and these +edits within the batch are applied in order. Note that we called Delete before +Put so that if key1 is identical to key2, we do not end up erroneously dropping +the value entirely. + +Apart from its atomicity benefits, `WriteBatch` may also be used to speed up +bulk updates by placing lots of individual mutations into the same batch. + +## Synchronous Writes + +By default, each write to leveldb is asynchronous: it returns after pushing the +write from the process into the operating system. The transfer from operating +system memory to the underlying persistent storage happens asynchronously. The +sync flag can be turned on for a particular write to make the write operation +not return until the data being written has been pushed all the way to +persistent storage. (On Posix systems, this is implemented by calling either +`fsync(...)` or `fdatasync(...)` or `msync(..., MS_SYNC)` before the write +operation returns.) + +```c++ +leveldb::WriteOptions write_options; +write_options.sync = true; +db->Put(write_options, ...); +``` + +Asynchronous writes are often more than a thousand times as fast as synchronous +writes. The downside of asynchronous writes is that a crash of the machine may +cause the last few updates to be lost. Note that a crash of just the writing +process (i.e., not a reboot) will not cause any loss since even when sync is +false, an update is pushed from the process memory into the operating system +before it is considered done. + +Asynchronous writes can often be used safely. For example, when loading a large +amount of data into the database you can handle lost updates by restarting the +bulk load after a crash. A hybrid scheme is also possible where every Nth write +is synchronous, and in the event of a crash, the bulk load is restarted just +after the last synchronous write finished by the previous run. (The synchronous +write can update a marker that describes where to restart on a crash.) + +`WriteBatch` provides an alternative to asynchronous writes. Multiple updates +may be placed in the same WriteBatch and applied together using a synchronous +write (i.e., `write_options.sync` is set to true). The extra cost of the +synchronous write will be amortized across all of the writes in the batch. + +## Concurrency + +A database may only be opened by one process at a time. The leveldb +implementation acquires a lock from the operating system to prevent misuse. +Within a single process, the same `leveldb::DB` object may be safely shared by +multiple concurrent threads. I.e., different threads may write into or fetch +iterators or call Get on the same database without any external synchronization +(the leveldb implementation will automatically do the required synchronization). +However other objects (like Iterator and `WriteBatch`) may require external +synchronization. If two threads share such an object, they must protect access +to it using their own locking protocol. More details are available in the public +header files. + +## Iteration + +The following example demonstrates how to print all key,value pairs in a +database. + +```c++ +leveldb::Iterator* it = db->NewIterator(leveldb::ReadOptions()); +for (it->SeekToFirst(); it->Valid(); it->Next()) { + cout << it->key().ToString() << ": " << it->value().ToString() << endl; +} +assert(it->status().ok()); // Check for any errors found during the scan +delete it; +``` + +The following variation shows how to process just the keys in the range +[start,limit): + +```c++ +for (it->Seek(start); + it->Valid() && it->key().ToString() < limit; + it->Next()) { + ... +} +``` + +You can also process entries in reverse order. (Caveat: reverse iteration may be +somewhat slower than forward iteration.) + +```c++ +for (it->SeekToLast(); it->Valid(); it->Prev()) { + ... +} +``` + +## Snapshots + +Snapshots provide consistent read-only views over the entire state of the +key-value store. `ReadOptions::snapshot` may be non-NULL to indicate that a +read should operate on a particular version of the DB state. If +`ReadOptions::snapshot` is NULL, the read will operate on an implicit snapshot +of the current state. + +Snapshots are created by the `DB::GetSnapshot()` method: + +```c++ +leveldb::ReadOptions options; +options.snapshot = db->GetSnapshot(); +... apply some updates to db ... +leveldb::Iterator* iter = db->NewIterator(options); +... read using iter to view the state when the snapshot was created ... +delete iter; +db->ReleaseSnapshot(options.snapshot); +``` + +Note that when a snapshot is no longer needed, it should be released using the +`DB::ReleaseSnapshot` interface. This allows the implementation to get rid of +state that was being maintained just to support reading as of that snapshot. + +## Slice + +The return value of the `it->key()` and `it->value()` calls above are instances +of the `leveldb::Slice` type. Slice is a simple structure that contains a length +and a pointer to an external byte array. Returning a Slice is a cheaper +alternative to returning a `std::string` since we do not need to copy +potentially large keys and values. In addition, leveldb methods do not return +null-terminated C-style strings since leveldb keys and values are allowed to +contain `'\0'` bytes. + +C++ strings and null-terminated C-style strings can be easily converted to a +Slice: + +```c++ +leveldb::Slice s1 = "hello"; + +std::string str("world"); +leveldb::Slice s2 = str; +``` + +A Slice can be easily converted back to a C++ string: + +```c++ +std::string str = s1.ToString(); +assert(str == std::string("hello")); +``` + +Be careful when using Slices since it is up to the caller to ensure that the +external byte array into which the Slice points remains live while the Slice is +in use. For example, the following is buggy: + +```c++ +leveldb::Slice slice; +if (...) { + std::string str = ...; + slice = str; +} +Use(slice); +``` + +When the if statement goes out of scope, str will be destroyed and the backing +storage for slice will disappear. + +## Comparators + +The preceding examples used the default ordering function for key, which orders +bytes lexicographically. You can however supply a custom comparator when opening +a database. For example, suppose each database key consists of two numbers and +we should sort by the first number, breaking ties by the second number. First, +define a proper subclass of `leveldb::Comparator` that expresses these rules: + +```c++ +class TwoPartComparator : public leveldb::Comparator { + public: + // Three-way comparison function: + // if a < b: negative result + // if a > b: positive result + // else: zero result + int Compare(const leveldb::Slice& a, const leveldb::Slice& b) const { + int a1, a2, b1, b2; + ParseKey(a, &a1, &a2); + ParseKey(b, &b1, &b2); + if (a1 < b1) return -1; + if (a1 > b1) return +1; + if (a2 < b2) return -1; + if (a2 > b2) return +1; + return 0; + } + + // Ignore the following methods for now: + const char* Name() const { return "TwoPartComparator"; } + void FindShortestSeparator(std::string*, const leveldb::Slice&) const {} + void FindShortSuccessor(std::string*) const {} +}; +``` + +Now create a database using this custom comparator: + +```c++ +TwoPartComparator cmp; +leveldb::DB* db; +leveldb::Options options; +options.create_if_missing = true; +options.comparator = &cmp; +leveldb::Status status = leveldb::DB::Open(options, "/tmp/testdb", &db); +... +``` + +### Backwards compatibility + +The result of the comparator's Name method is attached to the database when it +is created, and is checked on every subsequent database open. If the name +changes, the `leveldb::DB::Open` call will fail. Therefore, change the name if +and only if the new key format and comparison function are incompatible with +existing databases, and it is ok to discard the contents of all existing +databases. + +You can however still gradually evolve your key format over time with a little +bit of pre-planning. For example, you could store a version number at the end of +each key (one byte should suffice for most uses). When you wish to switch to a +new key format (e.g., adding an optional third part to the keys processed by +`TwoPartComparator`), (a) keep the same comparator name (b) increment the +version number for new keys (c) change the comparator function so it uses the +version numbers found in the keys to decide how to interpret them. + +## Performance + +Performance can be tuned by changing the default values of the types defined in +`include/leveldb/options.h`. + +### Block size + +leveldb groups adjacent keys together into the same block and such a block is +the unit of transfer to and from persistent storage. The default block size is +approximately 4096 uncompressed bytes. Applications that mostly do bulk scans +over the contents of the database may wish to increase this size. Applications +that do a lot of point reads of small values may wish to switch to a smaller +block size if performance measurements indicate an improvement. There isn't much +benefit in using blocks smaller than one kilobyte, or larger than a few +megabytes. Also note that compression will be more effective with larger block +sizes. + +### Compression + +Each block is individually compressed before being written to persistent +storage. Compression is on by default since the default compression method is +very fast, and is automatically disabled for uncompressible data. In rare cases, +applications may want to disable compression entirely, but should only do so if +benchmarks show a performance improvement: + +```c++ +leveldb::Options options; +options.compression = leveldb::kNoCompression; +... leveldb::DB::Open(options, name, ...) .... +``` + +### Cache + +The contents of the database are stored in a set of files in the filesystem and +each file stores a sequence of compressed blocks. If options.cache is non-NULL, +it is used to cache frequently used uncompressed block contents. + +```c++ +#include "leveldb/cache.h" + +leveldb::Options options; +options.cache = leveldb::NewLRUCache(100 * 1048576); // 100MB cache +leveldb::DB* db; +leveldb::DB::Open(options, name, &db); +... use the db ... +delete db +delete options.cache; +``` + +Note that the cache holds uncompressed data, and therefore it should be sized +according to application level data sizes, without any reduction from +compression. (Caching of compressed blocks is left to the operating system +buffer cache, or any custom Env implementation provided by the client.) + +When performing a bulk read, the application may wish to disable caching so that +the data processed by the bulk read does not end up displacing most of the +cached contents. A per-iterator option can be used to achieve this: + +```c++ +leveldb::ReadOptions options; +options.fill_cache = false; +leveldb::Iterator* it = db->NewIterator(options); +for (it->SeekToFirst(); it->Valid(); it->Next()) { + ... +} +``` + +### Key Layout + +Note that the unit of disk transfer and caching is a block. Adjacent keys +(according to the database sort order) will usually be placed in the same block. +Therefore the application can improve its performance by placing keys that are +accessed together near each other and placing infrequently used keys in a +separate region of the key space. + +For example, suppose we are implementing a simple file system on top of leveldb. +The types of entries we might wish to store are: + + filename -> permission-bits, length, list of file_block_ids + file_block_id -> data + +We might want to prefix filename keys with one letter (say '/') and the +`file_block_id` keys with a different letter (say '0') so that scans over just +the metadata do not force us to fetch and cache bulky file contents. + +### Filters + +Because of the way leveldb data is organized on disk, a single `Get()` call may +involve multiple reads from disk. The optional FilterPolicy mechanism can be +used to reduce the number of disk reads substantially. + +```c++ +leveldb::Options options; +options.filter_policy = NewBloomFilterPolicy(10); +leveldb::DB* db; +leveldb::DB::Open(options, "/tmp/testdb", &db); +... use the database ... +delete db; +delete options.filter_policy; +``` + +The preceding code associates a Bloom filter based filtering policy with the +database.

For example: + +```c++ +class CustomFilterPolicy : public leveldb::FilterPolicy { + private: + FilterPolicy* builtin_policy_; + + public: + CustomFilterPolicy() : builtin_policy_(NewBloomFilterPolicy(10)) {} + ~CustomFilterPolicy() { delete builtin_policy_; } + + const char* Name() const { return "IgnoreTrailingSpacesFilter"; } + + void CreateFilter(const Slice* keys, int n, std::string* dst) const { + // Use builtin bloom filter code after removing trailing spaces + std::vector<Slice> trimmed(n); + for (int i = 0; i < n; i++) { + trimmed[i] = RemoveTrailingSpaces(keys[i]); + } + return builtin_policy_->CreateFilter(&trimmed[i], n, dst); + } +}; +``` + +Advanced applications may provide a filter policy that does not use a bloom +filter but uses some other mechanism for summarizing a set of keys.
