Alan Paxton a16e2ff82a Adapt benchmark result script to new fields. (#10120 ) Summary: Recently merged CI benchmark scripts were failing. There has clearly been a major revision of the fields of benchmark output. The upload script expects and sanity-checks the existence of some fields (changes date to conform to OpenSearch format)..., so the script needs to change. Also add a bit more exception checking to make it more obvious when this happens again. We have deleted the existing report.tsv from the benchmark machine. An existing report.tsv is appended to by default, so that if the fields change, later rows no longer match the header. This makes for an upload that dies half way through the report file, when the format no longer matches the header. Re-instate the config.yml for running the benchmarks, so we can once again test it in situ.

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 especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/main/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.

Questions and discussions are welcome on the RocksDB Developers Public Facebook group and email list on Google Groups.
