What problem does this PR solve?
Issue Number: close #69912
Related PR: #68786, #57821
Problem Summary:
PR #68786 made external binary mapping permanently enabled, so Hive/HMS
BINARYcolumns are exposed as DorisVARBINARYandenable.mapping.varbinary=falsecan no longer restore the oldSTRINGmapping.The Hive UDF documentation describes Bitmap/HLL UDF output that uses Doris serialized binary data, while the existing
bitmap_from_base64andhll_from_base64functions require Base64STRINGvalues. Therefore, the documented Hive UDF consumption path cannot directly read the currentVARBINARYresult.Add direct binary conversion functions:
The binary readers validate external input and return row-level
NULLfor malformed values. Bitmap deserialization additionally validates Roaring containers and consumed bytes to prevent incorrect parsing and backend memory-safety failures.hll_from_binaryis also allowed in Stream Load and Broker Load mappings.Release note
Add direct
VARBINARYconversion functions for Doris Bitmap and HLL values, with safe handling of malformed binary input.Check List (For Author)
