@sivchari I took another look. Let's keep this but make it concurrency safe
l.53

var syncLoopStarted atomic.Bool

l.56

syncLoopStarted.Store(true)

l.85

if !syncLoopStarted.Load() {

@SubhasmitaSw
Thank you for commenting about it. Surely, it might be right, but I think it's not necessary. In l.83, we check if all workers starts by atomic.Load(&workers) < int64(c.syncConcurrency) and I believe it's enough to achieve to block data race. Thanks.

The check in l.83++ does not include the syncloop (l.53-l.63)

syncLoopStarted := false
go func() {
log.Info("Starting sync loop")
syncLoopStarted = true
for {
select {
case <-time.After(c.syncPeriod / 4):
