superfly/litefs v0.2.0

on GitHub

Overview

The v0.2.0 release primarily focuses on stability and hardening, however, it also includes a few important features. This release is also marks the end of the alpha phase of LiteFS and it is now considered "beta" software. It should generally run well, however, please report bugs to the GitHub repository.

Major features

Candidacy

By default, every node in the cluster can become the primary node. However, moving a primary from one region to another can change performance characteristics significantly so it may be useful to only allow certain nodes to become primary. You can now set the candidate flag in the config to false for any nodes which should not become primary:

candidate: false

Static Lease

LiteFS uses Consul to dynamically change the current primary in the cluster on the fly. However, for users that do not wish to run Consul, they can set a single fixed primary node. This is similar to how Litestream's read replication was meant to work. Please see #47 for more details.
