hooklee2000 commented 2 months ago

it raise exception when handle bigint:

java.lang.UnsupportedOperationException: org.apache.parquet.column.values.dictionary.DictionaryValuesWriter$PlainIntegerDictionaryValuesWriter
        at org.apache.parquet.column.values.ValuesWriter.writeLong(ValuesWriter.java:119)
        at org.apache.parquet.column.values.fallback.FallbackValuesWriter.writeLong(FallbackValuesWriter.java:192)

we need also treat the schema of bigint as int64. fixes #6
