Issue fixed in this release:

  • Config: The file workdir option is not working. The root cause was scylla.yaml parsing of options with both short and a long formats, like workdir and work_directory #7478, #9500 , #11503
  • Stability: Lightweight transactions are now more robust when the schema is changed during a transaction. #10770
  • Stability: COMPACT STORAGE tables allow the user to only specify a prefix of a compound clustering key. Bugs relating to such partial keys and reversed rows were fixed.Note that compact storage is deprecated (see section). #12180
  • Stability: Reading fails after inserting clustering keys with a missing component for frozen or frozen #12242
  • Stability: reactor stalls, caused by quadratic behavior, when inserting sstables into backlog tracker on schema change during disrupt_add_drop_column #12499
  • Tools: a fix in scylla sstable: data_dictionary_impl might return invalid data #12875
