* Fully managed code, platform independent and without reference to other libraries. * Multi-threaded, with a solution for deadlocks resolving/elimination, parallel reads and synchronized writes/reads. * No fixed scheme for table names (construction and access on the fly). * Tables can reside in mixed locations: different folders, hard drives, memory. * Liana-Trie indexing technology. Database indexes (keys) never need to be defragmented. Speed of insert/update/remove operations doesn't grow up during the time. * Ability to access Key/Value pair of a table by physical link, what can economize time for joining necessary data structures - approach of Graph Databases. * No limits for database size (except "long" size for each table and physical resources constraints). * Low memory and physical space consumption, also while random inserts and updates. Updates reside the same physical space, if necessary. * High performance of CRUD operations. * High speed of random keys batch insert and updates (batch must be sorted in memory ascending and non-overwrite flag must be set). * Nested / Fractal tables which can reside inside of master tables values. * Incremental backup/restore option. * Integrated text-search subsystem (full-text/partial). * DBreeze is a foundation for complex data storage solutions (graph/neuro, object, document, text search etc. data layers). Please, study documentation to understand all abilities of DBreeze.

* 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
