What is changed

  • Refactor TSDataType switch handling into TypeService implementations.

  • Update Tablet decoding and AlignedTVList WAL handling for TsFile 2.4.1-SNAPSHOT.
  • Merge the latest master branch changes.

Validation

  • DataNode and related regression tests passed.
  • ArchUnit TSDataType switch checks passed without a baseline.
  • REST Chinese-locale test compilation passed.

Float.MIN_VALUE and Double.MIN_VALUE are the smallest positive values, not lower bounds. With this initialization, MAX ignores zero and all negative FLOAT/DOUBLE inputs, leaving inits false and returning NULL. The existing CI tests testFloatMaxWithNonPositiveInput, testDoubleMaxWithNonPositiveInput, and testDoubleMaxWithNonPositiveIntermediateInput reproduce this regression. Please keep the previous NEGATIVE_INFINITY initialization or use another true lower bound.

Fixed in the updated branch: grouped FLOAT/DOUBLE MAX now initializes with Float.NEGATIVE_INFINITY and Double.NEGATIVE_INFINITY, so zero and negative values can initialize the result. All 3 GroupedMaxAccumulatorTest cases pass, including non-positive intermediate input.

Type.setTo(TsPrimitiveType, Column, int) copies the primitive into the column; it does not copy the column value into the primitive. This call therefore leaves xResult at its default value and can overwrite the input column. CI reproduces this in AccumulatorTest.maxByAccumulatorTest (-99 expected, 0 returned). Please use the correct column-to-primitive copy operation.

Fixed in the updated branch: setXResult now uses the column-to-primitive setter to copy the selected input into the result, without writing into the source column. The testMaxMinByReadsXWithoutModifyingInput regression verifies both result replacement and input preservation; the DataNode TypeServicesTest suite passes.

default:
throw new UnSupportedDataTypeException(String.format(DATATYPE_UNSUPPORTED, dataType));

Type.serializeArray uses TsFile's binary-array format, which writes a presence byte before each binary value. The Tablet reader in RAW_ARRAY_BYTE_BUFFER_DESERIALIZER_SERVICE still reads the legacy Tablet format (length + payload only, with nulls represented by the separate bitmap), so the first presence byte is interpreted as part of the length and the stream becomes misaligned. CI fails with BufferUnderflowException in InsertMultiTabletsNodeSerdeTest. Please preserve the existing Tablet wire format or update both serialization, size calculation, and all readers together.

Fixed in 5eb7694245c. Both ByteBuffer and DataOutputStream Tablet writers now use dedicated TypeService serializers that preserve the legacy length-plus-payload format. Null binary values retain a zero-length placeholder and use the existing separate bitmap; no TsFile presence byte is added. The new regression checks exact bytes for TEXT, STRING, BLOB and OBJECT, including nulls, empty values and inactive rows. InsertTabletNodeSerdeTest and InsertMultiTabletsNodeSerdeTest pass.

The WAL size calculation now uses Type.serializedSize, whose binary-array size includes a presence byte, but WAL_ARRAY_WRITER_SERVICE still writes only the length and payload. The calculated WAL entry size therefore disagrees with the bytes actually written, which breaks WAL offsets/search indexes. The three WALFileTest failures in CI reproduce this. Please use a size calculation matching the WAL writer's wire format.

Fixed in 5eb7694245c. Tablet and WAL size calculation now share a range-aware calculator that counts exactly the bytes written by the legacy WAL writer: length plus payload, including null placeholders, over [start, end). A regression compares the calculated size with the actual bytes written for a non-zero-start binary slice. All 5 WALFileTest cases pass; the targeted DataNode serialization/WAL run passed 31 tests.

🟡 Changes recommended

The architecture check is not repository-wide, and several new localized-message definitions violate established naming and localization requirements.

Fixed in 5eb7694245c. Added architecture-test to the default reactor with an aggregate production classpath covering the Java modules, including library-udf, JDBC and examples. Its ArchUnit/ASM check scans org.apache.iotdb without a violation baseline; the existing DataNode check remains explicitly scoped to org.apache.iotdb.db. The aggregate module includes the rule regression tests for ordinary switches, lambdas, anonymous classes, valid TypeService implementations and unrelated methods. Both the aggregate and DataNode architecture suites pass (7 tests each). Remaining client/example/REST type dispatches were migrated to TypeService.
