Whenever a configuration option is used in a “one shot” fashion it could be dynamically
fetched instead of requiring a process restart.
This would give greater configuration control without restarts as well as provide a central
configuration place (no need to update every configuration file on every server).
- The timeout for an operation is fixed at the start of each operation …
- … VS the database server requires a restart to change.
Why delay improving?
- Needs are yet unknown.
- Config will likely see large changes.
- Split the configuration object into two static objects:
- Static configuration options are left in the existing file.
- Dynamic configuration options are moved to a new file.
- Change the dynamic configuration object to have a more dynamic API.
- Possibly implement some wrapper type that
DeRef to the requested type and is
loaded when accessed (possibly cache in memory for sanity).
- Possibly not so the cost/risk of dynamic lookup can be exposed.
- Consider a dynamic configuration loader that returns a static view on the full
dynamic configuration options vs dynamic loading of individual attributes.
- Keep the stored format decoupled from the exposed interface (mainly the full
configuration should be stored and picked from by the API).
- Provide an official way to update dynamic configuration (
- Update user code, if needed, to use a dynamic fetch API.
- At startup, warn if the dynamic config loaded is not the same as the dynamic config file?
Downsides the new solution/idea
- Extra complexity in the code.
- Extra deployment complexity (need a configuration store of sorts).
- Less obvious configuration methods (upload configuration file to store? Changes done with
