Is there an option to override this at the table-level? What is the default for compression - is it on/off?
I have added some information about this. Also included code snippets below, but feel free to ignore those if its TMI
Compression on disk is controlled by the following flag:
By default, it is enabled. Start the processes with the flag set to
falseto disable compression.
93 DEFINE_bool(enable_ondisk_compression, true, 94 "Determines whether SSTable compression is enabled or not.");
Default compression type is Snappy.
462 options->compression = rocksdb::Snappy_Supported() && FLAGS_enable_ondisk_compression 463 ? rocksdb::kSnappyCompression : rocksdb::kNoCompression;
