Issues solved in this release:

  • iotune may report incorrect write bandwidth #4064
  • After a Linux kernel upgrade, Scylla may stop serving requests. This root cause is a bug in the Linux RWF_NOWAIT feature that can cause it to return EIO under some uncertain conditions, even though everything is fine. #3996
  • In extreme out-of-memory situations, failure to allocate an internal data structure used for synchronizing memtable flushes can result in a segmentation fault and crash. #3931
  • In some cases, Scylla streaming failure stop the bootstrap of a new node joining the cluster #3732
  • Wrong values if Size_estimates. Size_estimates is a field in a Scylla system table which holds statistics on table size per node. Tools like Spark are using this field to calculate how large its reads should be #3916
