* NoSQL - An advanced, ACID-compliant, key-value store based on our traditional ISAM engine. * +SQL - c‑treeACE is also a full SQL engine, which sits on top of our ACID NoSQL key-value store. * Multimodel - Our multimodel approach is unique in the way our NoSQL and SQL engines complement each other. * Reliability - c‑treeACE is a nearly zero-administration database. * High Availability - HA through hot backups, replication, and auto-recovery * Performance - Fine tuning the application provides unprecedented performance. * Security - With numerous mechanisms to enforce data-access policies to advanced data encryption. * ACID Transactions - c‑treeACE provides ACID guarantees on both NoSQL and SQL transactions, concurrently. * Platforms - An ideal choice when you need interoperability between the many supported platforms. * Tools - A complete suite of GUI and command-line/scriptable utilities.

* 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
