Summary:
This diff includes an initial script running a set of benchmarks for
regression test. The script does the following things:
checkout the specified rocksdb commit (or origin/master as default)
make clean && DEBUG_LEVEL=0 make db_bench
setup test directories
run set of benchmarks and store results
Currently, the script will run couple benchmarks, store all the benchmark
output, extract micros per op and percentile information for each benchmark
and store them in a single SUMMARY.csv file. The SUMMARY.csv will make the
follow-up regression detection easier.
In addition, the current script only takes env arguments to set important
attributes of db_bench. Will follow-up with a patch that allows db_bench
to construct options from an options file.
Test Plan:
NUM_KEYS=100 ./tools/regression_test.sh

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.
