Maintenance and Servers Discussion for Typesense

TLDR Carlo asked about maintenance and primary node assignment in Typesense. Kishore Nallan explained that Typesense requires no maintenance and operates on either 1 or 3+ servers. No override available in their clustering framework.

Two quick question that I couldn't find from the site.
• Does typesense require any maintenance (think db optimizations)
• Is there a way to make it work in a mode where it always accepts a given node as the primary node? (Planning on running in k8s with 2 nodes I want to avoid getting in the situation where I Get stuck because it cannot pick the right primary node)

1. There are no maintenance operations.
2. Typesense uses raft which needs three instances for quorum.

So typesense can only work with 1 or 3+ servers? Not two?

Yes. Nothing stopping you from running two servers but if one server goes down both will reject writes and reads because there is no quorum and without quorum there will be split brain.

Makes sense.No way to override I guess? (Within k8s you node 0 will always be up 1 way or aound,thats' why I asked)

The clustering framework we use doesn't allow that type of override

Addressing Typesense Server Issues and Optimization Needs

Robert had an issue with a 'stuck' typesense server. Jason and Kishore Nallan gave advice on handling writes, configuration for high search volumes, and running multiple typesense instances. They also recommended monitoring CPU usage and updating the server version for bug fixes.
