DSE 6.8.3 Highlights
-
Support for Storage Attached Indexes (SAI)
DSE database
-
Fixed a bug where on clusters with small token counts sstableloader could fail. (DB-4463)
6.8.3 DSE database
Changes and enhancements:
-
Storage-Attached Indexing (SAI) completed its Beta and is now a generally available (GA) DSE feature. Use it to create one or more secondary indexes on DSE tables. See (SAI).
-
Support for
decimalandvarintdata types with SAI indexed columns. (DSP-20794 and DSP-17647) -
SAI metrics can be exposed via Metrics Collector and Grafana. DataStax provides prepackaged Grafana dashboards that integrate with DSE Metrics Collector. Use DSE Metrics Collector to export metrics to a monitoring tool like Prometheus, and then visualize the metrics in the Grafana dashboards. See the GitHub-hosted Metrics Reporter resources. Specifically for SAI metrics, refer to Monitor SAI indexes. (DSP-21111)
-
Support for collection indexing via SAI, and querying CQL collections. See CREATE CUSTOM INDEX and the SAI collection map examples. (DSP-20014)
Resolved issues:
-
Fixed a bug where on clusters with small token counts sstableloader could fail. (DB-4463)
Known issues:
-
None.
6.8.3 DSE Search
Changes and enhancements:
-
Search-related latency metrics will now decay in time like other metrics. Named queries (using query.name parameter) will now have separate latency metrics. New mbean atributes are available for search latency metrics: TotalLatency (us), Min, Max, Mean, StdDev, DurationUnit, MeanRate, OneMinuteRate, FiveMinuteRate, FifteenMinuteRate, RateUnit, 98th, 999th. (DSP-19612)
-
Fixed a bug where after several months of up time an encrypted index wouldn’t accept more writes unless the core is reloaded. (DSP-21234)
6.8.3 DataStax Graph
Changes and enhancements:
-
This change allows traversal in to UDTs via the 'properties' and 'values' steps. (DSP-21248)
-
Fixed type mismatch errors in graph traversals that use simplePath() and as() in presence of search index on edges with composite vertex keys (DSP-21309)
