Note
Medium Risk
Touches core RowBinary array decoding and adds new array accessors, which could affect how existing array columns (especially empty and enum arrays) are materialized and what exceptions are thrown.
Overview
Adds a new
getObjectArray()API toClickHouseBinaryFormatReaderandGenericRecord(and wires it throughAbstractBinaryFormatReader,MapBackedRecord, andBinaryReaderBackedRecord) to read Array columns asObject[], including recursive conversion for nested arrays and support for non-primitive element types.Improves array decoding and convenience accessors:
getStringArray()now also supportsArray(Enum*)by returning enum names, empty arrays preserve an appropriate element type, andBinaryStreamReaderbetter infers primitive element types (includingfloat/double) plus adds recursiveArrayValue.toObjectArray().Adds extensive unit and integration coverage for 1D/2D/3D arrays, empty arrays, nullable elements, list-backed array decoding via type hints, and error conditions when calling array methods on non-array columns.
