Start with the linked CI run and io.debezium.connector.postgresql.PostgresConnectorIT.customSnapshotterSkipsTablesOnRestartWithConcurrentTx at PostgresConnectorIT.java:1769. Trace the Awaitility condition named “Streaming was not started on time” and reproduce the restart with a concurrent transaction. Done means the test completes reliably without the reported timeout.
