Appending Data

[MarkMcCullagh]

Hi

I'm creating a data ouput to run some metrics. Initially these will be end of month but I'd like to be able to look at daily change of caseloads. At the moment I create an Excel file for a specific date and then append data into a cumulative Excel file. We're talking roughly 3000 records daily x 26 fields. I'd like this to be appended automatically in the future. I presume the output tool can append into some output file automatically - which format is best, Any information would be appreciated.

Regards 

Mark

Hi @MarkMcCullagh ,

Something like the below should work. You can input your comprehensive data, then pull your daily data and union them together. After that you would want to 'Block Until Done' and write back over the top of your original file.

Hi @MarkMcCullagh ,

The best format is, by far, yxdb.

Instead of appending automatically, since yxdb files is not able to do that, I suggest you to do as following.

The block until done guarantees your file will be closed before start writing in it.

Let me know if that works for you.

Best,

Thanks for the replies. I'll implement a yxdb solution later.with Block to prevent the workflow from crashing
