Hi Yash, Gareth,
Not something obvious, but as explained in
https://dzone.com/articles/whats-wrong-java-8-part-iii
hoping to *blindly *use Parallel Streams for intensive computation tasks is not
a good idea :)

Yes, Usage of the stream will surely enhance performance to a certain
extent and removes ceremony from the code base. I think Parallel streams
will add enhancements in many folds as we are using a multicore processor
(I have not tested yet), but the Functional approach seems promising.
Thanks & Regards,

forUpdate
We patched EntityFindOptions with a new field "forUpdate" with shorthand
methods in EntityQuery to enable. We then made a change to
GenericDAO.selectListIteratorByCondition
to add "FOR UPDATE" on the end of the SQL select statement - this allows
for DB row locks (we use postgres and works but have not tested other
databases). I believe there may have been a discussion about this before
forEach on EntityQuery
Use Consumer in java and groovy to iterate over a query. This can reduce
memory consumption (replacement for queryList()) and boiler plate code (eg
queryIterator(), while loop and close)
Example:
EntityQuery.use(delegator).from("Foobar")
.forEach(item ->
Debug.logInfo(item.toString(), module);
);
A further update could be to provide stream capabilities
Hope this helps, I can provide a patch aswell

Hello Gareth,
Please provide some more details or patch to understand - forUpdate and
forEach method utility.
getFieldMap method looks good to me.

Hi all
We have internally patched EntityQuery with some additional
functionality and before I create a Jira was going to see what the
community thinks.
New functionality:
- New method getFieldMap which returns a Map object of selected
fields from GenericValue objects, useful for creating cache map
objects for lookup
- Support forUpdate
- forEach method to accept Consumer
We have found these useful and believe the project can benefit, let me
know what you think
