https://www.elastic.co/cloud/as-a-service/pricing mentions that there is an option for HA (High Availability) that offers replication and automatic fail over.
A few questions about replication:
- Is this active replication?
- Is there any lag in replication?
- Does it guarantee no data loss in case of failover?
I am asking because I haven't seen replication as a feature offered in open source version of elasticsearch. I am curious how does this work internally. That would help us make right decision/s going forward. Thank you so much.
