Open Messages from a managed source to query records retained in its ClickHouse landing table. The browser supports:
  • JSON field predicates and value facets
  • landed-at and broker timestamp ranges
  • partition and offset ranges
  • stable preview columns
  • cursor pagination
  • full-record inspection up to 16 MiB
Message searches read raw__<source> landing history. They do not query Kafka, change a consumer group, or alter the source. Broker inventory, consumer lag, and retained-message queries remain separate operations so one unavailable signal does not disable the others.
Expanded retained JSON message with Kafka and landing metadata
Retained-message visibility is bounded by the source landing TTL. The browser cannot recover data that ClickHouse has already expired.
See Topics for broker-only metadata and Replay and Lineage for normalized replay columns and boundary semantics.
