leveldb

Compare

  Analyzed about 19 hours ago

LevelDB is a library that implements a fast key-value store. Features * Keys and values are arbitrary byte arrays. * Data is stored sorted by key. * Callers can provide a custom comparison function to override the sort order. * The basic operations are Put(key,value) ... [More] , Get(key), Delete(key). * Multiple changes can be made in one atomic batch. * Users can create a transient snapshot to get a consistent view of data. * Forward and backward iteration is supported over the data. * Data is automatically compressed using the Snappy compression library. * External activity (file system operations etc.) is relayed through a virtual interface so users can customize the operating system interactions.

Modula-2 collections library. The library provides an API for collection ADTs, in particular: stacks, queues, double ended queues, priority queues, balanced binary search trees, patricia tries, dynamic arrays and hash tables to store arbitrary data. The hash table ADT allows data to be stored and ... [More] retrieved by reference or by copy, with built-in reference counting. All other ADTs allow data to be stored and retrieved by reference only. The library follows PIM4, it has no dependencies and it is platform independent. The library is tested with GM2 using option 'fpim4'. Under development. BSD style license. [Less]

RocksDB

Compare

Claimed by Facebook Analyzed 3 days ago

RocksDB is an embeddable persistent key-value store for fast storage. RocksDB can also be the foundation for a client-server database but our current focus is on embedded workloads. RocksDB builds on LevelDB to be scalable to run on servers with many CPU cores, to efficiently use fast storage, to ... [More] support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation. [Less]

  Analyzed about 7 hours ago

Stash is a persistence engine for .NET. It eschews relational models and object/relational mapping and instead follows the No-Sql paradigm of storing serialised graphs or ‘documents’. It is effectively a Key/value store with access via Indexes. Stash currently uses BerkeleyDB as its ... [More] persistence store. Other persistent engines may be implemented. [Less]
