Add configurable BBolt sync interval for improved performance on network mounts#4169
Conversation
…ork mounts Adds storage.bbolt.syncinterval config option that controls how often BBolt flushes committed transactions to disk. By default (0) every transaction is flushed immediately. Setting a positive interval (e.g. 1s) batches flushes via a background goroutine, significantly improving write throughput on network mounts such as SMB/Azure Files.

Summary
Adds a
storage.bbolt.syncintervalconfiguration option that controls how often BBolt flushes committed transactions to disk.0), every transaction is flushed immediately (existing behaviour, no change)1s) batches flushes via a background goroutine, significantly improving write throughput on network mounts such as SMB/Azure FilesPerformance tests on Azure ACI with an SMB volume mount showed ~4× improvement in transaction throughput (55 → 212 tx/s average) when combined with the read lock removal (go-stoabs#146). See the analysis in #4162 for full details.
The risk of data loss on a hard crash is low for network-replicated data, since any transactions not yet flushed will be re-synced from peers on restart.
Depends on go-stoabs#4 (
