Andrew Kryczka 5df172da2f fix deletion-triggered compaction in table builder
Summary:
It was broken when `NotifyCollectTableCollectorsOnFinish` was introduced. That function called `Finish` on each of the `TablePropertiesCollector`s, and `CompactOnDeletionCollector::Finish()` was resetting all its internal state. Then, when we checked whether compaction is necessary, the flag had already been cleared.

Fixed above issue by avoiding resetting internal state during `Finish()`. Multiple calls to `Finish()` are allowed, but callers cannot invoke `AddUserKey()` on the collector after any finishes.
Closes https://github.com/facebook/rocksdb/pull/2936

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

Build Status 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/
