v0.2.0-beta.1...main

v0.2.0-beta.1 Release (July 15, 2020)

• Avoid unnecessary term update (for past election requests for term prior to current--still needed for equal to current)

• Add grace period after election before a new election can begin (prevent exiting / partially partitioned members from causing election thrash)
• Add mutex to prevent write race

• Add availability tracking

v0.2.0-beta.0...edge

v0.2.0-beta.0 Release (July 3, 2020)

Changelog

• Update protobuf messages to include client interface information and enable redirect (note: this is incompatible with v0.1.0 records, so a v0.2.0 node will not be able to use persistent data from a v0.1.0 node)
• Nodes now issue a 307 redirect message to clients for writes (PUT and DELETE), redirecting the request to the current leader
• Change node configuration to be done via environment variables (rather than a combination of command-line flags and a config file)
• Fix bug in election majority calculation for even numbers of nodes in a cluster
• Update/tweak install and use of code generation tools (swag, protobuf, and autorest)
• Remove dependencies no longer used
