Spartan Posted April 12, 2016 Author Report Share Posted April 12, 2016 Kyoto Tycoon (0.9.56) Written in: C++ Main point: A lightweight network DBM License: GPL Protocol: HTTP (TSV-RPC or REST) Based on Kyoto Cabinet, Tokyo Cabinet's successor Multitudes of storage backends: Hash, Tree, Dir, etc (everything from Kyoto Cabinet) Kyoto Cabinet can do 1M+ insert/select operations per sec (but Tycoon does less because of overhead) Lua on the server side Language bindings for C, Java, Python, Ruby, Perl, Lua, etc Uses the "visitor" pattern Hot backup, asynchronous replication background snapshot of in-memory databases Auto expiration (can be used as a cache server) Best used: When you want to choose the backend storage algorithm engine very precisely. When speed is of the essence. For example: Caching server. Stock prices. Analytics. Real-time data collection. Real-time communication. And wherever you used memcached before.

Spartan Posted April 12, 2016 Author Report Share Posted April 12, 2016 RethinkDB (2.1) Written in: C++ Main point: JSON store that streams updates License: License: AGPL (Client: Apache) Protocol: Proprietary JSON document store Javascript-based query language, "ReQL" ReQL is functional, if you use Underscore.js it will be quite familiar Sharded clustering, replication built-in Data is JOIN-able on references Handles BLOBS Geospatial support Multi-datacenter support Best used: Applications where you need constant real-time upates. For example: Displaying sports scores on various displays and/or online. Monitoring systems. Fast workflow applications Quote Link to comment Share on other sites More sharing options...
sattipandu Posted April 12, 2016 Report Share Posted April 12, 2016 3 minutes ago, Spartan said: ElasticSearch (0.20.1) Written in: Java Main point: Advanced Search License: Apache Protocol: JSON over HTTP (Plugins: Thrift, memcached) Stores JSON documents Has versioning Parent and children documents Documents can time out Very versatile and sophisticated querying, scriptable Write consistency: one, quorum or all Sorting by score (!) Geo distance sorting Fuzzy searches (approximate date, etc) (!) Asynchronous replication Atomic, scripted updates (good for counters, etc) Can maintain automatic "stats groups" (good for debugging) Best used: When you have objects with (flexible) fields, and you need "advanced search" functionality. For example: A dating service that handles age difference, geographic location, tastes and dislikes, etc. Or a leaderboard system that depends on many variables. This is the best of the lot as far as i know and have used fukk mongo Quote Link to comment Share on other sites More sharing options...

dasara_bullodu Posted February 7, 2017 Report Share Posted February 7, 2017 On 4/12/2016 at 6:58 PM, Spartan said: Redis (V3.0RC) Written in: C Main point: Blazing fast License: BSD Protocol: Telnet-like, binary safe Disk-backed in-memory database, Dataset size limited to computer RAM (but can span multiple machines' RAM with clustering) Master-slave replication, automatic failover Simple values or data structures by keys but complex operations like ZREVRANGEBYSCORE. INCR & co (good for rate limiting or statistics) Bit operations (for example to implement bloom filters) Has sets (also union/diff/inter) Has lists (also a queue; blocking pop) Has hashes (objects of multiple fields) Sorted sets (high score table, good for range queries) Lua scripting capabilities (!) Has transactions (!) Values can be set to expire (as in a cache) Pub/Sub lets one implement messaging Best used: For rapidly changing data with a foreseeable database size (should fit mostly in memory). For example: To store real-time stock prices. Real-time analytics. Leaderboards. Real-time communication. And wherever you used memcached before. Redis is not dbno ... redis is db cache Quote Link to comment Share on other sites More sharing options...
