>             Project: Ignite
>          Issue Type: Bug
>          Components: cache
>    Affects Versions: 2.6

> The following logic is executed under write lock within flushing logic:
> {code:java}
> applyBatch(pending, true, null);
> {code}
> [https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/store/GridCacheWriteBehindStore.java#L1120]
>  In combination with IGNITE-5003 it may cause locking of a put/remove operation for the first value in next batch while the whole current batch is applying.
> applyBatch(pending, true, null); should be moved out of the lock guarded section.
