> Print a warning if HashMap is passed into bulk update operations
> ----------------------------------------------------------------
>
> Key: IGNITE-6804
> URL: https://issues.apache.org/jira/browse/IGNITE-6804
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Reporter: Denis A. Magda
> Assignee: Ilya Kasnacheev
> Priority: Critical
> Labels: usability
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Ignite newcomers tend to stumble on deadlocks simply because the keys are
> passed in an unordered HashMap. Propose to do the following:
> * update bulk operations Java docs.
> * print out a warning if not SortedMap (e.g. HashMap,
> Weak/Identity/Concurrent/Linked HashMap etc) is passed into
> a bulk method (instead of SortedMap) and contains more than 1 element.
> However, we should make sure that we only print that warning once and not
> every time the API is called.
> * do not produce warning for explicit optimistic transactions
> More details are here:
