DSE 6.9.x is compatible with Apache Cassandra™ 3.11 and adds additional production-certified changes, if any. Components that are indicated with an asterisk (*) (if any) are known to be updated since the prior patch version.

Release notes for 6.9.3

14 October 2024

Components versions for DSE 6.9.3

  • Apache Solr™ 6.0.1.5.2973
  • Apache Spark™ 2.5.0.2*
  • Apache TinkerPop™ 3.4.15-20240705-ffb48eb3
  • Apache Tomcat® 8.5.94
  • DSE Java Driver 1.10.0-dse-20240930* (DSE internal-only version)
  • Netty 4.1.100.1.dse
  • Spark JobServer 0.8.0.56

6.9.3 DSE Cassandra

  • Fixed sstablescrub to run with -t disabled by default. (DSP-24501)
  • Added guardrail warning for large columns in cassandra.yaml file. The new field is called column_value_size_warn_threshold_in_kb can can be used to get warned when a column is larger than a given value. By default this field is not used. (DSP-24384)
  • Replaced the out-dated in-tree Management API code with the updated OSS version from GitHub k8ssandra/management-api-for-apache-cassandra. This should not affect any DSE 6.9 users except for situations where DSE 6.9 Docker images are being used with Management API enabled. Those cases will be fixed in a future DSE 6.9.x release.

6.9.3 DSE Graph

  • Fixed count() query in classic graph. (DSP-24336)
  • Fixed Spark default JVM options (resources/spark/conf/java-opts) to work with Java 11. (DSP-24512)

6.9.3 DSE Performance

  • Changed the default location of the histogram aggregation work, offloading it by default to a thread pool different than the main one. This unblocks the TPC threads when large numbers of tables exist. (DSP-24520)

6.9.3 DSE Node/DseTool

  • Updated Debian package dependencies on libaio1 so that it can be installed on Ubuntu 24.04 (Noble Numbat). (DSP-24359)
