Vector Search Dashboard

The Vector Search dashboard now shows each index in its own tab #2915. Each tab has three rows:

  • Overview: “Stored Vectors in index” is now “Indexed items”. The build-rate panel now shows the modification rate per operation, which includes updates and removes.

  • Indexing: indexing lag (P50/P99), and CDC reader status, checkpoint age, handler errors and restarts.

  • Full-text search: index size, segment count, and highlight request rate and latency. The row only shows for full-text indexes.

Panels that have no data for an index are hidden.

  • Fix missing stat panel titles in the vector search and manager dashboards #2915

  • scylla-overview: exclude the sl:driver service level when All service levels are selected #2917
