## Description The pipe receiver periodically reduces repeated statement exception logs, but the current reducer key contains the receiver id, the full statement logging string, and the exception message. For high-cardinality insert traffic, these fields make otherwise identical failures unique and allow stack traces to flood the log. This PR: - reduces statement exceptions by statement class, root-cause class, and the root cause's first stack frame; - ignores receiver ids, statement payloads, and dynamic exception messages in the reducer key, while keeping different failure locations independently visible; - adds a compact Pipe logging string for `InsertRowsStatement` that reports the row count and first/last row summaries without serializing all row values. The underlying statement exception or NPE is intentionally unchanged; this PR only prevents repeated failures from producing unbounded logs and bounds the size of the remaining `InsertRowsStatement` entries. ## Tests - `mvn spotless:apply -pl iotdb-core/datanode` - `mvn test -pl iotdb-core/datanode -Dtest=IoTDBDataNodeReceiverTest` - `mvn test-compile -pl iotdb-core/datanode -P with-zh-locale -DskipTests` - verified English and Chinese `DataNodePipeMessages` key parity This PR has: - [x] been self-reviewed. - [x] added comments explaining the intent of the reducer key. - [x] added or updated unit tests for the new behavior. --- ##### Key changed/added classes - `IoTDBDataNodeReceiver` - `InsertRowsStatement` - `IoTDBDataNodeReceiverTest` -- This is an automated message from the Apache Git Service.
