Yes, SQL delete in a UV stage versus a reload of the file.

If I keep deleteing records daily, should I expect over time a degradation of performance that will eventually require a reload? I am trying to asses the maintenance impact of one method versus the other.

Hashed files - delete recs vs reload

Hello,
If I delete records from a hashed file does that significantly influence the file's performance? Is it better to unload/reload the entire file, filtering out the records I do not need?
Thanks

I did not explain it correctly. I was referring to the 'out link' as the link that goes from the Row Generator Transformer to the UV stage. So, it would be the UV stage input link.

I will try the method you suggested, but can you see a reason why the SQL would not execute with my design?

Craig,
I still do not see it. Here is what I have from the index list on string 'dsget':

DSGetJobInfo
DSGetLinkInfo
DSGetLogEntry
DSGetLogSummary
DSGetNewestLogId
DSGetParamInfo
DSGetProjectInfo
DSGetStageInfo
etc..

This is 7.5.1 help.

Thanks
