Peter Dillinger 66cd07c6d9 Exclude more Travis builds for each pull request (#6557 ) Summary: This commit fixes an incorrect version of this change that was previously landed. On recently adding ARM64 and PPC64LE builds to Travis, we seem to have hit some parallel build limits that dramatically increased queue times. This change majorly limits the configurations for ARM64 and PPC64LE to build on each pull request, but keeps the large matrix for branch builds. In the process, I changed some previously excluded osx build configurations to happen in branch builds. NB: we might want to move master branch Travis build to daily trigger rather than push trigger to further reduce contention.

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 especially 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/
