• Upgrade mimir to 2.15.0
  • Ingester: Change -initial-delay for circuit breakers to begin when the first request is received, rather than at breaker activation.
  • Query-frontend: apply query pruning before query sharding instead of after.
  • Ingester: Replace cortex_discarded_samples_total label from sample-out-of-bounds to sample-timestamp-too-old.
  • Querier: The . pattern in regular expressions in PromQL matches newline characters. With this change regular expressions like .* match strings that include \n. To maintain the old behaviour, you will have to change regular expressions by replacing all . patterns with [^\n], e.g. foo[^\n]*. This upgrades PromQL compatibility from Prometheus 2.0 to 3.0. #9844
  • Ingester: improve performance of reading the WAL.
  • Querier: improve performance and memory consumption of queries that select many series.
