DataStax Enterprise 5.1.23

3 May 2021

⚠️ NOTE: Due to a bug which affects DSE 5.1.23, this release has been retracted. We recommend against upgrading to this version at this time. This bug is already addressed in DSE 5.1.24. All features and fixes for 5.1.23 are present in 5.1.24.

Components versions for DSE 5.1.23

  • Apache Solr™ 6.0.1.0.2841*

DSE 5.1.23 Core

  • Adds a new flag -t for sstablescrub to update deletion times which are in the future. It accepts a command-line argument: -t . All deletion times further in the future than the given number of days will be reset to the current time. (DB-4912)

DSE 5.1.23 Schema

  • CDC property per table is now propagated regardless CDC is enabled in yaml or not. CDC property is not propagated when there are nodes running C* 3.0 or DSE 5.0 in the cluster (upgrade state). During the upgrade we also prohibit toggling CDC property on per-table basis. (DB-4926

DSE 5.1.23 SSTables

  • Fixes SRCCLR-SID-22742: Insecure Input Validation Vulnerability in the Apache Commons Codec library (DSP-21747)

DSE 5.1.23 Search

  • Fixed a bug where FilterCache warmup triggered by node health change can block GossipStage-1 thread for several seconds (DSP-21674)
  • Fixed a bug where under heavy load solr query worker threads would use 100% CPU due to contention on thread local map (DSP-21746)
  • A new jvm option is added: “dse.search.fc.warmup”: AUTO, ALWAYS & NEVER. Warmup will be disabled for cases when it’s either set to NEVER or set to AUTO with Non-Static type for cover finder & Vnodes are enabled. For all other scenarios, it will be enabled. (DSP-21813)

When unset, the default number of max expansions is 50. (DSP-21605)

5.1.21 DSE Security

  • When optimized group retrieval was used in memberof_search mode (ldap_options.all_parent_groups_search_type parameter in dse.yaml), DSE confused attributes specified by ldap_options.user_memberof_attribute and ldap_options.all_parent_groups_memberof_attribute making the optimized search work only in case both attributes were set to the same value.
