Constructor Details

BigIntegerParquetBytesCodec

public BigIntegerParquetBytesCodec(String args)

BigIntegerParquetBytesCodec

public BigIntegerParquetBytesCodec(int encodedSizeInBytes)

Parameters:

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.
