I had a weird observation in our Elasticsearch Cluster. We have an ES Query that will be executed from a python script.
When the Query is being fired from python, right away a task will get created under
GET /_tasks with a task id on NODE A
The query runs about 3 to 4 minutes to fetch the results. Meanwhile, for every minute the task id changes and runs over a different node(NODE B, NODE C, NODE E, etc.,)
There are no other queries running in the cluster. Still, After a minute the same query will be given to a different node.
I wanted to analyze the total time taken for query execution with out enabling slow logs. This is the primary reason we have chosen
GET /_tasks API
I am stuck here on my analysis part. Any help would be really appreciated
