Subject Re: Cannot run query containing inner join on Phoenix 3.0.0 when data size increased from 10 MB to 1 GB
Date Mon, 24 Feb 2014 23:08:35 GMT
Hi Maryann,

The sizes of each table in my query are as follows:
customer - 24 MB
orders - 164 MB
lineitem - 725 MB
supplier - 1.4 MB
nation - 2.2 KB
region - 400 B

The heap size of my region servers is 4 GB.

Thank you,
David
