Subject Re: Parquet test files with all data types
Date Sun, 17 Mar 2019 09:26:51 GMT
Hello Andy,

I guess these files stem from the beginning of the Parquet format, when only INT96 timestamps
were available. Feel free to add more of them. Using the Java implementation is best, this
is definitely the reference through age and wide usage.
