> Team,
> In our organization we are still using Hudi 0.5.0. We would upgrade to the latest version in couple of quarters.
> problem scenario :
> Many use cases in our project using COW and hive sync is disabled. One of the Hudi contains two years worth of data , which are partitioned by date. For every write on this table, i notice that Listing leaf files and directories job triggered twice. Normally it is triggered only once. Attache the screenshot.
>
> once the first listing leaf files and directories are done then another listing of leaf files and directories logs are rolled.
> I spent some time in investigating the source code but couldn't trace where exactly it is being invoked .
>
> How can it be avoided here? Unfortunately this one is adding up more latency in our flow.
