> Parallelization of Jobs
> -----------------------
>
> Key: FINERACT-428
> URL: https://issues.apache.org/jira/browse/FINERACT-428
> Project: Apache Fineract
> Issue Type: Improvement
> Components: Loan, Savings
> Affects Versions: 1.1.0
> Reporter: Avik Ganguly
> Assignee: Markus Geiss
> Priority: Major
> Labels: gsoc, p2, performance
> Fix For: 1.2.0
>
>
> For starters, it will be useful to have some technical configuration added as
> job parameter for each of the below jobs, that is batch size and thread pool
> size for executor service so this has a dependency on FINERACT-425.
> Add migration script to add those 2 configurations to each of the following
> jobs with the value of batch size being 500 and thread pool size being 16 :-
> Add Accrual Transactions
> Add Periodic Accrual Transactions
> Add Accrual Transactions For Loans With Income Posted As Transactions
> Generate Loan Loss Provisioning
> Post Interest for Savings
> Update Loan Summary
> This would require separation of core functionality to a separate class.
> Simplified example :-
> ```
> final ExecutorService executor = Executors.newFixedThreadPool(threadPoolSize);
>
> final LocalDate dueDate = DateUtils.getLocalDateOfTenant();
> final Collection<LoanAccountData> loansToBeRepaidData =
> this.loanReadPlatformService
> .retrieveLoansToBeRepaidFromAdvancePayment(dueDate);
> Iterable<List<LoanAccountData>> loansToBeRepaid =
> Iterables.partition(loansToBeRepaidData, batchSize);
> final Authentication authentication =
> SecurityContextHolder.getContext().getAuthentication();
> List<Callable<Object>> advancePaymentPosters = new
> ArrayList<Callable<Object>>();
>
> for (List<LoanAccountData> subList : loansToBeRepaid) {
> AdvancePaymentPoster poster = (AdvancePaymentPoster)
> this.applicationContext.getBean("advancePaymentPoster");
> poster.setLoans(subList);
> poster.setTenant(ThreadLocalContextUtil.getTenant());
> poster.setAuthentication(authentication);
> poster.setCommandService(commandService);
> advancePaymentPosters.add(Executors.callable(poster));
> }
> try {
> List<Future<Object>> responses =
> executor.invokeAll(advancePaymentPosters);
> for(Future f : responses) {
> f.get();
> }
> } catch (InterruptedException e1) {
> e1.printStackTrace();
> }
>
> executor.shutdown();
> ```
