[Feature] CONFIG SET rename-command #640

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I find it would be interesting to allow using the CONFIG SET and CONFIG GET 
commands for the rename-command configuration property.

That would allow making a node read-only or write-only at will.

The main problem I have with doing this is that it changes the exported 
semantic at run-time. All the configuration directives have effect on the inner 
workings of Redis, while the behavior doesn't change. In addition, Redis is 
currently unable to persist its configuration to disk. When there are commands 
that are renamed at run-time, the exported set of commands changes across 
restarts. Instead, when the rename statements are issued via the configuration 
file, this is made explicit and is less likely to result in errors (expecting a 
command to be renamed after restart while it isn't).

This all follows from the fact that the configuration cannot be persisted at 
the moment which would be a great feature to begin with (although it has its 
own set of problems).

Leaving this open for now because it is interesting and I don't want to rule it 
out just yet.

+1 for resolving this because of the following use case: in hosted Redis 
environments the config files are usually not accessible to users so the 
simplest way is to allow CONFIG for supported operations. Maybe the way to 
resolve the main problem is to disconnect all clients after changing exported 
semantics at runtime.

-1 for "in addition": 2.8 added config-rewrite
