> This is related to Garbage Collection. 
> The problem is more severe than FLINK-25512 because there is leftover after materialization truncation each time (if pre-emptive uploads are enabled).
> However, the probability can still be not high because of grouping of backends into a single file (so only if ALL the backends on TM materialize semi-simultaneously then it happen).
