Maximum Number of Columns Can be used in Column analysis

Hi Team,
This is regarding perfomance of Profiling.
How many columns at max can be used in column analysis?
How many indicators at max can be use per column?
Do we have any best practice document for the same?
Just to give you a ruff idea about table, around 200 columns and from DB we are going to use 3 Million records for analyis.
Thanks,
avrjraja

Hi avrjraja

I have consulted to our developers and got answer that there is no limitation on the number of columns and indicators. If you have problems to add columns or indicators in a analysis, please post your problem in forum or create a jira issue.

Re: Maximum Number of Columns Can be used in Column analysis

@avrjraja Did you manage to get around it?

Whenever I try to run my analysis (I have 216 columns and 2.5 million records) , it fails saying disk space error. Can anyone please suggest how much space does it require? Will 8 GB on C drive be enough? I am using a delimited source to run my column analysis.
How to avoid this situation? Any pointers will be appreciated!
Thanks!
