README
## 1.TerichDB
TerichDB is an open source NoSQL data store based on terark storage engine.
TerichDB 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](http://terark.com/blog/detail/2)
## 2.Features
- 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
## 3.Installation
### 3.1.Linux & MacOS
```
sudo wget https://raw.githubusercontent.com/Terark/terichdb/master/online_install.py && (python online_install.py; rm online_install.py)
```
### 3.2.Windows
[windows installation guide](http://terark.com/docs/2)
## 4.Compile TerichDB
### 4.1.Dependencies
- libboost_system.so(1.63.0) (boost_1_63_0)
- libboost_filesystem(1.63.0)(Could be found in boost_1_63_0)
- libwiredtiger.so(v2.8.0)
- libtbb.so(tbb44_20160128)
- libgflags
- libsnappy
- libz
- libzstd
### 4.2.Compiler Support
- Linux : `g++-4.7`, `g++-4.8`, `g++-4.9`, `g++-5.3`, `g++-5.4`, `g++-6.1`, `g++-6.2`
- Mac OS : `g++-4.8`, `g++-4.9`, `g++-5.3`, `g++-6.0`, `g++-6.1`, `clang++-7.3`
- Windows : `vs2015`
### 4.3.`dfadb` alternative
1. TerichDB is open source but our core data structures and algorithms(`dfadb`) are not yet.
2. `dfadb` is supported by a library named `terark-fsa-*` in our released packages.
3. Developers who want to build their own TerichDB, should place the `terark-fsa-*` library into their library search path(e.g. `/usr/local/lib`).
4. User compiled TerichDB can only uses limited APIs, and need to set `"ReadonlySegmentClass" : "MockReadonlySegment"` in `dbmeta.json`([TerichDB's schema file](http://terark.com/docs/4)).
## 5. Notes
- UNIX `fork()` should not be called in the applications using TerichDB, this would cause undefined behaviors.
