> I experience an issue, when zookeeper creates snapshots every 5-10 minutes.
> First, I suspected lots of transactions, which overload the ransaction log and rotate it - but, that's no the case. Each transaction log contains not more than 300-400 transactions (I opened one log file using zookeeper utility and at the end of this log there's a record "OF reached after 328 txns."
> Log dile size is also not big - less than 1 MB.
> Snapshot file is pretty big, though - it contains ~400k znodes. Also, there are about 2000 simultaneous sessions open to this zookeeper node. But that does not directly explain - why snapshots are rotated so fast.
>  
> So, I'm wondering - what could be the reason for such frequent rotation?
>  
>  Thank you in advance.
