Hi devs,
I think that for data that are both not critical and high volume we should use ElasticSearch instead of saving them in our RDBMS.
Why ElasticSearch and not Solr or something else? There are many comparisons on the web between these two. I wouldn't chose one or another without an investigation. I agree that data that are both not critical and high volume could be stored outside our RDBMS. Thanks, Marius
So the idea would be to have an embedded ES in XWiki by default (using the permanent directory to store its data) and admins could configure XWiki to use a separate ES instance (very similar to what we do with SOLR).
Whenever a user modifies/creates/deletes/does operations on XObjects/etc, this is sent to ES.
The AS UI queries ES to display the data.
The Stats UI does the same.
Pros: - scalability - performance - extensibility. It’s easy to evolve the schema in ES, and we can easily have several formats (as was proven by the Active Installs code)
I’d like to start a POC in my “free” time.
WDYT?
Thanks -Vincent
