Custom Connectors vs Integrations

Hello,
what is the difference between both?

What custom connectors? Can you provide more context?

Are you talking about these connectors?

Yes, I read about it here:
How to create custom connectors for Elasticsearch - Elasticsearch Labs

Never used connector, but it is more related to Enterprise Search cases, where you have data that is not time based and want to search on it.

Hey @leandrojmp ,
yeah interesting, I saw they have a SQL Server Connector but also there's a SQL Input Integration (sql module from metricbeat) which seems to do the same thing but like how you said they seem to serve different use cases
