> Key: IGNITE-28700
> URL: https://issues.apache.org/jira/browse/IGNITE-28700
> Project: Ignite
> Issue Type: Bug
> Components: replication ai3
> Environment: Apache Ignite:3.1.0 (migrated from 2.17.0)
> JDK:Java 21 (LTS)
>
> Topology:Multi-node clusters (2–3 nodes SharedNothing, both same-host and
> cross-host
> deployments). Distribution zones with `PARTITIONS=25`, `REPLICAS` tuned per
> zone.
>
> Workload:CEP engine — high write rate on entity / event tables (rules generate
> thousands of writes per second), all of which must be observable by
> downstream consumers
> (rule re-evaluation across nodes, audit, optional Kafka mirroring).
> Persistence: `aipersist` regions with checkpointing; `raft.fsync=true` for
> SharedNothing.
> Reporter: Kratika Agrawal
> Priority: Major
> Labels: ignite-3
>
> Ignite 2.x supported CDC via `CacheEntryListener` (JCache) and the cache
> change-event SPI,
> enabling streaming of cache mutations to Kafka, Pulsar, or other external
> systems for audit,
> search-index hydration, or downstream materialization.
> Ignite 3.1.0 removed both `CacheEntryListener` and the underlying
> continuous-query / change-event
> SPI. There is no streaming API (push or pull) for "tell me everything that
> changed in this
> table since timestamp/offset X".
> Ask:
> Document the intended 3.x pattern** for downstream replication /
> event-sourcing. Today's
> options (compute job broadcasts? application-side changelog tables? raft
> log tailing?) are
> not specified.
> 3. **Accept this as a regression** — 2.x users with downstream consumers
> (Kafka, Elasticsearch,
> audit) cannot migrate without rewriting their integration layer.
