Symas LMDB vs RocksDB: What are the differences?
What is Symas LMDB? *A memory-efficient database *. It is an extraordinarily fast, memory-efficient database which is developed for the OpenLDAP Project. With memory-mapped files, it has the read performance of a pure in-memory database while retaining the persistence of standard disk-based databases.
What is RocksDB? Embeddable persistent key-value store for fast storage, developed and maintained by Facebook Database Engineering Team. 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 support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation.
Symas LMDB and RocksDB can be primarily classified as "Databases" tools.
Some of the features offered by Symas LMDB are:
- Ordered-map interface
- Multi-thread and multi-process concurrency supported
On the other hand, RocksDB provides the following key features:
- Designed for application servers wanting to store up to a few terabytes of data on locally attached Flash drives or in RAM
- Optimized for storing small to medium size key-values on fast storage -- flash devices or in-memory
- Scales linearly with number of CPUs so that it works well on ARM processors
RocksDB is an open source tool with 14.6K GitHub stars and 3.19K GitHub forks. Here's a link to RocksDB's open source repository on GitHub.
