Nathan Bronson 631863c63b track WriteBatch contents
Summary:
Parallel writes will only be possible for certain combinations of
flags and WriteBatch contents.  Traversing the WriteBatch at write time
to check these conditions would be expensive, but it is very cheap to
keep track of when building WriteBatch-es.  When loading WriteBatch-es
during recovery, a deferred computation state is used so that the flags
never need to be computed.

Test Plan:
1. add asserts and EXPECT_EQ-s
2. make check

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

Build Status

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/
