System Impacts – read carefully

Due to a bug (#2752 see below) in the 1.7.x experimental Counters features, upgrading to 1.7.5 may cause updates to counters values. If you are using experimental Counters in 1.7.4, let us know and we will guide you on evaluating the effect before the upgrade.

Bugs fixed in this release:

  • Counters: Updating from 1.7.4 to 2.0 breaks counters values #2752 (see system impact above)
  • Install: installing ScyllaDB on CentOS ignore patch version when specified #2642
  • Init: ScyllaDB init might never complete, get into a deadlock #2623
  • Init: On rare occasions, ScyllaDB might core dump when joining a cluster #2652
  • Init: Repair starting before node in NORMAL state may cause a core dump #2723
  • Init: Unable to start nodes with authenticator parameters #2273
  • Shutdown: ScyllaDB shutdown can get into infinite recursion when using TLS (secure connection) #2691, #2690
  • ScyllaDB may write incorrect cell names in promoted index blocks #2333
  • Failing to write an index file, for any reason, may result in a ScyllaDB crash #2673
  • A rare race condition may cause ScyllaDB to exit with “Assertion `_state != state::future’ failed.” message #2697
    Data update concurrent with schema update may fail with “attempted to mutate using not synced schema” #2617
