Hi,

We work with Postgresql DB to retrieve data into Qlik Sense.
We identified (in the attached example - retrieving 4 million records) that the query at the SQL level ends in around 40 seconds, while another process takes 4 minutes.

20240717T110810.305+0300 0024 LIB CONNECT TO 'PostgreSQL_localhost'
20240717T110811.328+0300 Connected.
20240717T110811.330+0300 0028 SQL SELECT *
20240717T110811.330+0300 0029 FROM table1
20240717T110811.330+0300 0030 WHERE "timestamp" > '2024-06-27 20:04:08'
20240717T110855.187+0300 43 fields found: field1, field2, field3, field4, field5, field6, field7, field8, field9, field10, field11, field12, field13, field14, field15, field16, field17, field18, field19, field20, field21, field22, field23, field24, field25, field26, field27, field28, field29, field30, field31, field32, field33, field34, field35, field36, field37, field38, field39, field40, field41, field42, timestamp
20240717T111256.239+0300 4,002,000 lines fetched
20240717T111257.239+0300 Execution finished.

Is it possible to get an explanation of what exactly happens after the query ends on Qlik side?

What exactly is done in the fetching phase that takes 4 minutes?

Is it possible to debug the matter using logs?

Thanks,

Eli.
