ParquetFilters.getParquetPrimitive() (line 223) has a TODO:
// TODO: this needs to convert to handle BigDecimal and UUID
The method handles Number, CharSequence, and ByteBuffer literal types, but does not handle BigDecimal (used for Iceberg decimal type) or UUID. When a predicate on a decimal or UUID column reaches the Parquet filter pushdown path, the method throws:
UnsupportedOperationException: Type not supported yet: java.math.BigDecimal
This prevents filter pushdown for decimal/UUID columns and can crash queries instead of gracefully falling back to post-scan filtering.
Expected behavior
BigDecimal should be converted to Parquet's Binary representation (fixed-length byte array with unscaled value)UUID should be converted to a 16-byte Binary (or the appropriate Parquet logical type representation)- Alternatively, return
null for unsupported types to skip pushdown gracefully rather than throwing
Affected file
ParquetFilters.java (line 223–234)
