Better understand SSTables Formats big vs bti


Where can I find more information on which Version of Cassandra supports which version of SSTables.

Recently I noticed DSE Cassandra is generating SSTables bti, while Apache Cassandra 3.11.4 continues to generate big.

Do you know what is the difference and when would Apache Cassandra start with bti

Thanks in advance!


Solution

  • The bti file format is proprietary file format developed by Datastax for DSE 6, so no information about its internals is available. It has a number of optimizations, so, for example, the key cache is not required anymore, etc. Apache Cassandra won't support it until the details of format will be opened by Datastax.
