Hi all, I’m looking into https://issues.apache.org/jira/browse/IGNITE-7264, and I need some guidance on what’s the best way to approach it.
The problem is that cache names are not restricted, but if persistence is enabled the cache needs to have a corresponding directory on the file system (“cache-…”) which can’t be created if the cache name contains certain characters (or a reserved system name). A straightforward approach would be to check if a cache name is allowed on the local system (e.g. via `Paths.get(name)`) and fail to create cache if it isn’t, but I’m a bit concerned with the consistency of the behavior (the same cache name be allowed on one system and not on another). I think a better way would be to replace special characters (say, all non-alphanumeric characters) with underscores in file names (not changing the cache configuration). Would this be OK? Are there any risks I’m not considering? WDYT? Thanks, Stan
