Ignite TC Bot commented on IGNITE-28858:
----------------------------------------
Docs Required triage: I checked the linked PR #359 in apache/ignite-extensions.
The change only adjusts CDC test timing and test helper constants under
modules/cdc-ext/src/test to reduce CI execution time; it does not change
user-facing CDC behavior, APIs, configuration, commands, or documentation text.
Removing Docs Required and leaving Release Notes Required for release-note
handling if needed.
> Reduce CDC replication tests execution time

> Follow-up to IGNITE-28857 (CDC replication test classes split). Two cheap
> changes in the CDC replication tests cut their execution time roughly in half
> (measured locally on CdcIgniteToIgniteReplicationThinClientTxTest):
> 1. walForceArchiveTimeout: 5000 -> 1000 ms. CDC consumes only archived WAL
> segments, so every replication wait in a test pays up to a 5 s
> segment-archive latency, several times per test. With 1 s the
> testActivePassiveReplication* subset went from 124.7 s to 78.3 s (-37%). The
> same value is also used by the PostgreSQL replication tests.
> 2. testWithExpiryPolicy TTL: 30 -> 10 s. The test waits for a real TTL
> expiration twice (source and destination). With TTL 10 s (and 1 s
> force-archive) the method went from 95.8 s (31.9 s per run) to 35.5 s (11.8 s
> per run, -63%). 10 s still leaves an order-of-magnitude margin over the
> observed replication lag.
> Expected effect: ~25-30 min less CPU across the Cdc suite; the slowest
> Parallel Tests batch after the split drops from ~10 to ~7 min.
