> In the current code in applyTransaction we have
> CompletableFuture<Message> future = CompletableFuture
> .supplyAsync(() -> runCommand(request, trxLogIndex)); We are using
> ForkJoin#commonPool.
> With the current approach we have 2 issues:
> # Thread exhausts when using this common pool.
> # Not a good practice of using common pool. Found some issues in our testing
> by using similarly in RatisPipelineUtils.
> # OM DB's across replica can be out of sync when the apply transactions are
> applied in out of order.
