- M4-LSM: The candidate generation and verification framework is implemented in server/src/main/java/org/apache/iotdb/db/query/dataset/groupby/LocalGroupByExecutor4CPV.java. The time index with step regression is implemented in tsfile/src/main/java/org/apache/iotdb/tsfile/file/metadata/statistics/StepRegress.java. The point pruning with value regression is implemented in tsfile/src/main/java/org/apache/iotdb/tsfile/file/metadata/statistics/ValueIndex.java.
- Some integration tests for correctness are in server/src/test/java/org/apache/iotdb/db/integration/m4/MyTest1.java.
