sagar commented on DERBY-6809:
------------------------------
Java 8 parallel array operations to sort filter etc. ... using inbuilt
mechanism provided by java8 api or lambdas and streams ...
with the derby source code still a blackbox to me ... I think probably this
might help in group by, having, where, etc. ...
it might also help in parallel execution of proceedures and functions which are
coded in java .... and hence developers can write them to take advantage of
parallelism ...
derby in embeddd mode will benefit hugely especially if it is deployed on
desktop laptop netbook class machine which are fairly low on computing power
but usually are at least dual core ...
yes smp/multicore parallel execution has some overheads but parallelism will
allow embeded derby to be used for more intensive oltp as well as olap
complicated queries even though inherently derby does not support olap out of
the box ... but a developer can write complicated queries subqueries aggregate
queries corelated subqueries and use functions to output the results ... if
certain derby finctionality can use parallelism ...
similarly ... for network server it will be even better and derby can be used
on even complex oltp or olap deployments ... again due to parallelism
> Java 1.8 feature use

> Key: DERBY-6809
> URL: https://issues.apache.org/jira/browse/DERBY-6809
> Project: Derby
> Issue Type: Improvement
> Components: Network Server
> Affects Versions: 11.0.0.0
> Reporter: sagar
>
> Suggestion ...
> Is it possible to auto modify the existing source code using tools like
> Netbeans, and take advantage of the new features in JDK 1.8 for better
> multiuser performance and better utilization of current day multicore
> processors?
> Plainly put, can we have from 11.0 onwards a version of derby which takes
> advantage of the advancements and new features in java 1.8 ...
