[BUG] Visualizations "Controls" autocompleteTimeout: Parameter not documented and

[awuetz]

Describe the bug

I wanted to use the visualization "controls" to have a dropdown list with predefined values which can be selected. This is working, but I noticed the exclamation mark, which tells me, that the list may be incomplete because the request is taking too long.
To work around this, i searched for the autocomplete settings in the opensearch_dashboards.yml file, but did not found anything about it. So by searching through this repo i suppose this settings are not documented in the default opensearch_dashboards.yml

After that i tried to set the autocompleteTimeout by looking through the code, so I tried:

opensearchDashboards.autocompleteTimeout: 600000

But with even 600000ms configured the warning in visualization "control" did not disappear.

To Reproduce

1. Create a visualisation of type "control"

OpenSearch Version opensearch docker image 1.2.3

Dashboards Version opensearch-dashboard docker image 1.2.0

Screenshots

Host/Environment (please complete the following information):

• OS: SLES 15 SP 3

How did you validate that the new timeout was enforced and that the request was still timing out? Do you have any steps to reproduce the issue?

Hello @awuetz, for first point I agree about the lack of information of possible configurations within OpenSearch Dashboards. There is a current issue here for the docs site to add more details: https://github.com/opensearch-project/documentation-website/issues/214.

got the same tried to increase autocompleteTimeout and autocompleteTerminateAfter settings in config:

user1@myhost:/usr/share/opensearch-dashboards/config$ grep "autocomplete" opensearch_dashboards.yml
opensearchDashboards.autocompleteTimeout: 900000
opensearchDashboards.autocompleteTerminateAfter: 900000

and then restarted the dashboard service, and checked it again, but didn't get positive result:

p.s.: btw, i remember that this visualization was working like a charm in Kibana after increasing similar parameters up to 120000 ms with less number of events per week (about ~7-8 million)

Hello, It seems that autocompleteTerminateAfter parameter is in nanoseconds while the autocompleteTimeout parameter is in milliseconds. Try with the following values, it works for me :

opensearchDashboards.autocompleteTimeout: 900000
opensearchDashboards.autocompleteTerminateAfter: 900000000
