I am hoping to understand the cause of this and hopefully find a solution - I have looked at every possible solution, but haven't been able to fix it.
Sitecore v10.0.2 using Solr 8.4.
In my current set up, Core DB is shared between CM and CD servers. Index update strategy for web dB is onPublishEndAsyncSingleInstance combined with remoteRebuild.
I created a new item and published it. Item was published to the web db, but the item didn't appear in the index(but item was updated in the index when I
set up the solr as local standalone instance).
I thought perhaps core db might have a play in this. So, I checked the event queue settings to see if it was set to true & it is.
When we trigger sitecore web index rebuild from sitecore
interface(control panel) then only remote solr instances indexes are getting updated.
All the events are processed in the event queue according to
EventQueueStats.aspx & in the event queue table as well.
What could be the cause of it?
