Warning! RocksDB is a fork of an earlier Google project called LevelDB, which was an embedded key-value store inspired by the low-level storage engine used by BigTable. It has the usual get, put, and delete operations, as well as an Iterator operation for scanning a range of consecutive K-V pairs from a given start key, a DeleteRange operation to delete a range of keys, and a Mergeoperation for read-modify-writes. Itâs either inserts or deletes, which is almost always the use case with time series data. Here are the results of a run on 100 million values spread out over 500k columns: ode> method of each of the storage engines.
