Summary: A couple of notes from the diff: - The namespace block I added at the top of table_properties_collector.cc was in reaction to an issue i was having with PutVarint64 and reusing the "val" string. I'm not sure this is the cleanest way of doing this, but abstracting this out at least results in the correct behavior. - I chose "rocksdb.merge.operands" as the property name. I am open to suggestions for better names. - The change to sst_dump_tool.cc seems a bit inelegant to me. Is there a better way to do the if-else block? Test Plan: I added a test case in table_properties_collector_test.cc. It adds two merge operands and checks to make sure that both of them are reflected by GetMergeOperands. It also checks to make sure the wasPropertyPresent bool is properly set in the method. Running both of these tests should pass: ./table_properties_collector_test ./sst_dump_test Reviewers: IslamAbdelRahman Reviewed By: IslamAbdelRahman Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D58119 |

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.
