Ingest pipeline->update by query updating only 999 documents?

[pathri (Vinit Pathri)]

POST /logdata/_update_by_query?pipeline=delete-referrer

Why this pipeline is updating only 999 documents at once?
and how to change it to whole index at once?

Thanks in advance

Update by query uses a scroll query behind the scenes and processes the results in batches. You can not perform the update in a single batch unless you have a very small index or number of matching documents. How is this causing a problem?

ohk thanks

but 1 more thing here, i have around 1million record in my index, this pipeline deleted around .7 million record at 1st go and showed a time out error and after that this is scrolling 999 records per execution :-

Then I guess you may need to tune the job and increase timeouts. Have a look in the docs for the options available. If you are deleting a majority of the data it can sometimes be easier to use the reindex API to copy the data you want to keep to a different index and then simply delete the original index.

i have tried creating an index (data for apache log) with below json

PUT /logdata

i have removed the field referrer while creating a new index and then i am reindexing it using below command

POST _reindex
{
"source": {
"index": "logs"
},
"dest": {
"index": "logdata"
}
}

in this case the index is getting populated but again with referrer field as it is there in logs index?

where am i going wrong??
