Task Definition key/value: validation_sampling_percentage

slewis — Thu, 02 Apr 2026 22:21:52 GMT

I'm looking at task definitions exported from Qlik Replicate 2025.11.0.164. In the list of source tables I noticed what appears to be a new key/value pair "validation_sampling_percentage": 0.

This key/value is not in the user guide and I can't find any reference to it when performing web searches. However I confirmed it is present for tasks connected to Oracle and SQL Server sources endpoints.

Can you please give me some information on this key/value (new or not), what it's used for, and how the value is set?

Example:

"source_tables": {

"name": "SOURCE_ENDPOINT_NAME",

"explicit_included_tables": [{

"owner": "SCHEMA_NAME",

"name": "TBL_NAME",

"orig_db_id": #######,

"table_type": 2,

"validation_sampling_percentage": 0,

"sapdb_def_ext_for_logstream": {

"$type": "SapdbOverLogstreamTableDefExt"

}

Hello @slewis ,

You may ignore it safely. It's not used in current supported versions.

thanks,

John.

Hi John, my question wasn't about concern for the task definitions safety. I was asking for information regarding the key/value and what it's past or future usage may be. If you could provide some detail it would be appreciated and would satisfy my curiosity. -- Thanks.

It has been deprecated in the current version and is no longer used.
