Does Ignition Edge have any internal storage for historical queries or small databases?

Hi everyone,

I'm working with Ignition Edge 8.3.1 and I know that Edge does not support traditional database connections in the same way as the full Ignition Gateway. However, for my application I really need to store small amounts of data locally — ideally something like a lightweight internal database or historical storage that I can query later for charts, tables, and reports.

Is there any built-in mechanism in Ignition Edge that allows this? Something like a small internal datastore, ring buffer, file-based history, or any feature that I can write to and later query? Or, if not, is there any recommended way to achieve this (for example, connecting to a full Ignition Gateway database, or using some Edge feature I might be missing)?

No.

Use flat text files or json or xml.

If you need actual SQL, Edge is not for you. (And trying to force it is violating your license.)

If you have Standard Ignition available in a gateway network, you can use system.util.sendRequest() to have the main gateway run queries for the Edge gateways.
