  • 0 - This version is currently written + * out by all RocksDB's versions by default. Can be read by really old + * RocksDB's. Doesn't support changing checksum (default is CRC32).
    • + *
  • 1 - Can be read by RocksDB's versions since 3.0. + * Supports non-default checksum, like xxHash. It is written by RocksDB when + * BlockBasedTableOptions::checksum is something other than kCRC32c. (version + * 0 is silently upconverted)
    • + *
  • 2 - Can be read by RocksDB's versions since 3.10. + * Changes the way we encode compressed blocks with LZ4, BZip2 and Zlib + * compression. If you don't plan to run RocksDB before version 3.10, + * you should probably use this.
    • + *
  • 3 - Can be read by RocksDB's versions since 5.15. Changes the way we + * encode the keys in index blocks. If you don't plan to run RocksDB before + * version 5.15, you should probably use this. + * This option only affects newly written tables. When reading existing + * tables, the information about version is read from the footer.
    • + *
  • 4 - Can be read by RocksDB's versions since 5.16. Changes the way we + * encode the values in index blocks. If you don't plan to run RocksDB before + * version 5.16 and you are using index_block_restart_interval > 1, you should + * probably use this as it would reduce the index size.
