Hello, I am from Philips Architecture team, where I am working on a POC to compare different data models [ Parquet/Avro/Json]. But I see Parquet is very slow while writing [pojo to Parquet file].
I have created two issues in Parquet project. One is regarding the slowness of ParquetWritter compared to JSON and AvroWriter : Avro Serialization Stats: StopWatch 'AvroSerializer': running time (millis) = 387 JSON serialization Stats: StopWatch 'JsonSerializer': running time (millis) = 103 Parquet Serialization Stats: StopWatch 'ParquetSerializer': running time (millis) = 8346 https://issues.apache.org/jira/browse/PARQUET-1680 Second issue is I was not able to serialize a Java object to Parquet when the pojo has a UUID field. Parquet is throwing exception. https://issues.apache.org/jira/browse/PARQUET-1679 Could you please help me on what I am doing wrong or give me some insights on resolving the issue.
