# Raft Configuration
|
|
|
|
Configuration options for running a Raft cluster in production.
|
|
|
|
## Cluster Size
|
|
|
|
For fault tolerance with `f` failures, you need `2f + 1` nodes:
|
|
|
|
- 3 nodes: tolerates 1 failure
|
|
- 5 nodes: tolerates 2 failures
|
|
- 7 nodes: tolerates 3 failures
|
|
|
|
## Election Timeout
|
|
|
|
The election timeout should be:
|
|
|
|
- At least 10x the network round-trip time (RTT)
|
|
- Typically 150-300ms in a single datacenter
|
|
- 500ms-2s across regions
|
|
|
|
## Heartbeat Interval
|
|
|
|
Set to roughly 1/3 to 1/10 of the election timeout:
|
|
|
|
```
|
|
heartbeat_interval = election_timeout / 3
|
|
```
|
|
|
|
## Log Compaction
|
|
|
|
Configure snapshot creation when the log grows too large:
|
|
|
|
| Threshold | Description |
|
|
|-----------|-------------|
|
|
| 10,000 entries | Minimum for frequent writes |
|
|
| 100MB | Size-based threshold |
|
|
| Daily | Time-based for low-write workloads |
|
