TerarkDB is an open source NoSQL data store based on terark storage engine.

TerarkDB is:

• Read optimized, faster than ever.
• Data is highly compressed and decompressed is not required before read.
• Use FSA and succinct technologies, totally different from B+ and LSM(Which is widely used in other data stores).
• Native support for regex expression query.
• Benchmark

• High Compression Ratio
  • Higher than snappy(2~5 times) and other database products, higher than gzip, sometimes higher than bzip
• Search Directly on Compressed Data without Decompression
  • Compressed data as index, index as compressed data
• Fast Access
  • Optimized for SSD and in-memory workloads
• Flexible Indexing
  • Multiple indexes on one table
  • Unique/non-unique index
  • Composite index(one index on multiple columns)
  • Ordered index (support range query)
• Native regular expression query
• Embeddable & Standalone Database
• Persistent
• Schema Based, with Rich Data Types
• Column Group
• Supported Platforms: Linux, Windows, Mac
• Transparent foundation for developers to build customized products

• libboost_system.so(1.60.0) (boost_1_60_0)
• libboost_filesystem(1.60.0)(Could be found in boost_1_60_0)
• libwiredtiger.so(v2.7.0)
• libtbb.so(tbb44_20160128)

• Linux : g++-4.8, g++-4.9, g++-5.3
• OS X : g++-5.3, g++-6.0, clang++-7.3
• Windows : vs2015

1. TerarkDB is open source but our core data structures and algorithms(dfadb) are not yet.
2. dfadb is supported by a library named fsa_all_* in our released packages.
3. Developers who want to build their own TerarkDB, should place the fsa_all-* library into their library search path(e.g. /usr/local/lib).
4. Self compiled TerarkDB can only uses limited APIs, and need to set "TableClass" : "MockDbTable" in dbmeta.json(TerarkDB's schema file).

TerarkDB follows Free Software Foundation's GNU AGPL v3.0
