Backport of #16789 to Flink 2.0 and 1.20. The
RowDataWrapperfiles were identical across the three versions, so this is a direct copy of the merged change: the fallback field getter for thedefaultcase ofbuildGetter(INT,BIGINT,BOOLEAN,FLOAT,DOUBLE,DATE) is pre-built once in the constructor instead of being recreated on everyget, which allocated two lambdas per field access on the partitioned-write, equality-delete and range-shuffle hot paths.Existing
TestRowDataWrappercoverage passes unchanged on both versions.AI Disclosure
