Sirveo Documentation

0.2.0 ✔️

Summary

This release implements a key capability from Sirveo’s roadmap; persistent stores. Flows can use three new KV nodes to store arbitrary JSON data in the server’s key-value store. Features include opt-in database persistence, optional key expiry and transparent in-memory caching, which can be bypassed for data reads.

Similar to the event browser, the UI has a new store browser to inspect (and remove) persistent items in the server’s key-value store. The next release will extend the store browser with support for memory-only store items.
