Possibility to update config without restart?

[enersis-pst]

Hello, is there a way to add, remove or change sources on a running service without restarting it?

Passing a user signal would be awesome. Webservers commonly do this. Or a --watch type flag to auto reload and clear the cache?

@enersis-pst / @four43 this has been discussed a few times, but an elegant solution has not yet been implemented. The community wants this support, but it's hard to account for all the various situations so the effort has atrophied a few times.

Here are a few references on the topic if you're interested:

• POC: watch config files to load/unload maps #948
• Map Loading/Unloading On-Demand #944
• Add ability to reload config at runtime #57
• Dynamic configuration #58

I'm not opposed to this idea but it does seem that it should be implemented with "experimental support" so the API could change as we learn about more use cases.
