["Caideyipi (via GitHub)" <gi...@apache.org>]

Caideyipi opened a new pull request, #18247:
URL: https://github.com/apache/iotdb/pull/18247

   ## Summary
   
   - backport #18240 to dev/1.3
   - reuse identity-deduplication sets across composite insert-node memory estimates
   - compose last-cache values lazily only for cache entries that can be updated
   - adapt the cache changes and opt-in benchmarks to the dev/1.3 DataNodeSchemaCache / DeviceLastCache layout
   
   ## Validation
   
   - `mvn -pl iotdb-core/datanode spotless:apply`
   - `mvn -o -nsu -pl iotdb-core/datanode -DskipTests test-compile`
   - `mvn -o -nsu -pl iotdb-core/datanode -Dtest=DataNodeSchemaCacheTest,DeviceLastCacheTest test` (6 tests passed in each of the two configured Surefire executions)
