Romain Manni-Bucau edited comment on DELTASPIKE-1402 at 6/1/20, 10:38 AM: -------------------------------------------------------------------------- I guess we need to refine the target: # hot reloading # bootstrap config (what if the config is mapped to a runtime model, it can be reloaded, it will never be refreshed) # immutable deployments (some deployments will not want to reload cause it means potentially breaking a valid deployment) # performances: most servlet container have a dev mode with reloading at read and a prod mode where it is disabled to avoid any IO which are cheap if done alone but can be expensive if the disk is used with an IO expensive app Therefore I suspect we can need a toggle to enable a refresh at read or a cached mode (read once). Using an enum it can enable us to add later a background refresh if needed so I would add something like {code:java} deltaspike.configsource.userhome.reloadStrategy=[SYNCHRONOUS_AT_READ|NONE|SKIP] {code} Side note: SKIP means "I don't want that, most apps of that machine use it but not me" Hope it makes sense. was (Author: romain.manni-bucau): I guess we need to refine the target: # hot reloading # bootstrap config (what if the config is mapped to a runtime model, it can be reloaded, it will never be refreshed) # immutable deployments (some deployments will not want to reload cause it means potentially breaking a valid deployment) # performances: most servlet container have a dev mode with reloading at read and a prod mode where it is disabled to avoid any IO which are cheap if done alone but can be expensive if the disk is used with an IO expensive app Therefore I suspect we can need a toggle to enable a refresh at read or a cached mode (read once).
