Quick Start

The current implementation focus is mode: ha.

Ports

• 9375/udp for HA peer traffic
• 9376/tcp for the management API
• 9377/tcp reserved for future KV peer traffic

What HA mode does

Each node:

• sends HA advertisements to one configured peer over unicast UDP
• validates packets for protocol version, group ID, and authentication
• tracks peer liveness and state
• chooses between INIT, BACKUP, and MASTER
• adds or removes VIP addresses on transition
• exposes status through 9376/tcp

Status

Query the local node:

gruezi status

Watch HA status continuously:

gruezi status --watch --interval-ms 1000 --node 127.0.0.1:9376

Important

gruezi should be read as work in progress.

• HA mode is the implemented path today
• service discovery is still pending
• distributed KV is still planned
