 The adapter supports a number of approaches for interfacing with Viya (`serverType` is `SASVIYA`).  For maximum performance, be sure to [configure your compute context](https://sasjs.io/guide-viya/#shared-account-and-server-re-use) with `reuseServerProcesses` as `true` and a system account in `runServerAs`.  This functionality is available since Viya 3.5.  This configuration is supported when [creating contexts using the CLI](https://sasjs.io/sasjs-cli-context/#sasjs-context-create).
