Andrew Kryczka 5aca977be8 env_basic_test library for testing new Envs [pluggable Env part 3] Summary: - Provide env_test as a static library. We will build it for future releases so internal Envs can use env_test by linking against this library. - Add tests for CustomEnv, which is configurable via ENV_TEST_URI environment variable. It uses the URI-based Env lookup (depends on D58449). - Refactor env_basic_test cases to use a unique/configurable directory for test files. Test Plan: built a test binary against librocksdb_env_test.a. It registered the default Env with URI prefix "a://". - verify runs all CustomEnv tests when URI with correct prefix is provided ``` $ ENV_TEST_URI="a://ok" ./tmp --gtest_filter="CustomEnv/" ... [ PASSED ] 12 tests. ``` - verify runs no CustomEnv tests when URI with non-matching prefix is provided ``` $ ENV_TEST_URI="b://ok" ./tmp --gtest_filter="CustomEnv/" ... [ PASSED ] 0 tests. ``` Reviewers: ldemailly, IslamAbdelRahman, lightmark, sdong Reviewed By: sdong Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D58485		9 years ago

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
