* Rich API - HyperDex provides one of the richest APIs in the NoSQL space. Its support for datatypes is unparalleled by other sharded data stores. It supports bulk asynchronous operations. And it boasts the fastest, consistent, online backups in the industry. * Consistency - HyperDex provides the strongest consistency properties of any open-source NoSQL system. Specifically, HyperDex guarantees that key operations are linearizable A client will always GET the value of the latest PUT. * Fault Tolerance - HyperDex ensures that data is replicated to withstand failures. This fault-tolerance threshold can be customized to an application's needs. The system guarantees seamless operation and automatic failover. * ACID Transactions - HyperDex Warp, a commercial extension to HyperDex, combines NoSQL performance with ACID transactions. Lightweight protocols underneath the covers ensure that this functionality comes with a minimal performance penalty. HyperDex Warp, with its ACID guarantees, is 2-10X faster than Mongo, and only 2% slower than HyperDex without ACID guarantees. * Performance - HyperDex is the fastest NoSQL system on the market, outperforming Mongo by 2-10X. Performance benchmarks provide the details.

* 100% compatible drop-in replacement for Lua 5.1, based on LuaJIT 2.1. Simply use #!/usr/bin/tarantool instead of #!/usr/bin/lua in your script. * full support for Lua modules and a rich set of own modules, including cooperative multitasking, non-blocking I/O, access to external databases, etc * MsgPack data format and MsgPack based client-server protocol * two data engines: 100% in-memory with optional persistence and a 2-level disk-based B-tree, to use with large data sets * multiple index types: HASH, TREE, RTREE, BITSET * asynchronous master-master replication * authentication and access control * the database is just a C extension to the app server and can be turned off
