Run DSVv3 json in parallel

[ognif]

Currently, I have a JSON file with many identical commands, but they are independent of each other. In other words, no block has a DependsOn entry.

According to AI, DSCv3 would execute such blocks in parallel and blocks with DependsOn in sequence. Unfortunately, I see that DSCv3 executes everything in sequence, which takes an extremely long time on an SQL Server. I can't let an SQL Server provisioning run for 5+ hours while DSCv1 takes barely an hour.

Therefore, I'd like to know how I can force DSCv3 to execute all the blocks in the JSON file in parallel as long as no DependsOn entry is present.

My DSCv3 execution via Ansible is divided into four JSON files which are executed sequentially: SQLServer install, filesystem, extras, and aggroup.

Have you tried DSC/ParallelGroup? As an example: https://github.com/PowerShell/DSC/blob/7f3a2c1c89765e67311f295d1a09ceca47b1c3b2/dsc/examples/parallel.dsc.yaml
