Felix Kizhakkel Jose updated PARQUET-1680:
------------------------------------------
Description:
Hi,
I am doing a POC to compare different data formats and its performance in
terms of serialization/deserialization speed, storage size, compatibility
between different language etc.
When I try to serialize a simple java object to parquet file, it takes _*6-7
seconds*_ vs same object's serialization to JSON is *_100 milliseconds._*
Could you help me to resolve this issue?
