ScyllaDB Enterprise Release 2018.1.8

The ScyllaDB team is pleased to announce the release of ScyllaDB Enterprise 2018.1.8, a production-ready ScyllaDB Enterprise minor release. ScyllaDB Enterprise 2018.1.8 is a bug fix release for the 2018.1 branch, the latest stable branch of ScyllaDB Enterprise. ScyllaDB Enterprise customers are encouraged to upgrade to ScyllaDB Enterprise 2018.1.8 in coordination with the ScyllaDB support team.

This release includes memory management improvements, first introduced in ScyllaDB Open Source 2.3 release and graduated into ScyllaDB Enterprise.

  • 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

Auditing: audit configuration syntax in scylla.yaml was changed from audit-categories and audit-tables to audit_categories and audit_tables. Note that the upgrade procedure does *not* update existing scylla.yaml automatically. More on ScyllaDB Enterprise auditing and auditing configuration here
