Summary: Hi, As part of some optimization, we're using multiple DB locations (tmpfs and spindle) to store data and configured max_bytes_for_level_multiplier_additional. But, max_bytes_for_level_multiplier_additional is not used to compute the actual size for the level while picking the DB location. So, even if DB location does not have space, RocksDB mistakenly puts the level at that location. Can someone pls. verify the fix? Let me know any other changes required. Thanks, Jay Closes https://github.com/facebook/rocksdb/pull/2704 Differential Revision: D5992515 Pulled By: ajkr fbshipit-source-id: cbbc6c0e0a7dbdca91c72e0f37b218c4cec57e28 |

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/
