Constructor Details

BigDecimalParquetBytesCodec

public BigDecimalParquetBytesCodec(int precision,
 int scale,
 int encodedSizeInBytes,
 RoundingMode roundingMode)

Parameters:

precision -

scale -

encodedSizeInBytes - encoded size in bytes, if fixed size, or -1 if variable size. note that according to the parquet spec, the minimum number of bytes required to represent the unscaled value should be used for a variable sized (binary) encoding; in any case, the maximum encoded bytes is implicitly limited by precision.
