PARQUET_FILE_SIZE question

Hi,

 

For different tables, when inserting i am setting diffferent PARQUET_FILE_SIZE, if i run multiple inserts in parallel (same user), will it work if set different size before each insert?

 

Thanks

Re: PARQUET_FILE_SIZE question

PARQUET_FILE_SIZE only affects the data written by impala, I am not sure what you mean by "will it work if set different size before each insert".

Regardless, PARQUET_FILE_SIZE should not break impala query.
