wgtmac opened a new pull request, #15244: URL: https://github.com/apache/arrow/pull/15244
As the parquet [specs](https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#decimal) states, DECIMAL can be used to annotate the following types: - int32: for 1 <= precision <= 9 - int64: for 1 <= precision <= 18; precision < 10 will produce a warning - fixed_len_byte_array: precision is limited by the array size. Length n can store <= floor(log_10(2^(8*n - 1) - 1)) base-10 digits - binary: precision is not limited, but is required. The minimum number of bytes to store the unscaled value should be used. The aim of this patch is to provide a writer option to use int32 to annotate decimal when 1 <= precision <= 9 and int64 when 10 <= precision <= 18. -- This is an automated message from the Apache Git Service.
