Taras Ledkov commented on IGNITE-3625:
--------------------------------------
[~vozerov],
It depends on the Ignite backward compatibility policy.
Now the most code to support both (old and new) types of IGFS cache
configurations is placed at the {{IgfsUtils}}:
- isIgfsCache
- prepareCacheConfigurations & validateLocalIgfsConfigurations
- get(Data|Meta)CacheName.
We can simplify these methods when old IGFS caches configurations is dropped.
> IGFS: Use common naming for IGFS meta and data caches.

> Key: IGNITE-3625
> URL: https://issues.apache.org/jira/browse/IGNITE-3625
> Project: Ignite
> Issue Type: Task
> Components: IGFS
> Affects Versions: 1.6
> Reporter: Vladimir Ozerov
> Assignee: Taras Ledkov
> Fix For: 2.0
>
>
> Currently IGFS is configured by passing names of two caches: meta and data.
> See {{FileSystemConfiguration.metaCacheName}} and
> {{FileSystemConfiguration.dataCacheName}}.
> These two caches are considered internal then and are not accessible for the
> user.
> We need to do the following during node startup:
> 1) If certain cache is configured as meta or data cache for multiple IGFS-es,
> or if it is configured as both meta and data cache for a single IGFS, then
> throw an exception.
> Relevant code pieces:
> {{IgfsProcessor.validateLocalIgfsConfigurations}}
> {{IgfsProcessorSelfTest}}.
> 2) During node startup change the name of this cache to
> {{igfs-IGFS_NAME-meta}} or {{igfs-IGFS_NAME-data}}. Change must be performed
> both inside IGFS config and cache config.
> Relevant code pieces:
> {{CacheConfiguration.name}}
> {{FileSystemConfiguration.metaCacheName}}
> {{FileSystemConfiguration.dataCacheName}}
> {{IgfsUtils.prepareCacheConfiguration}} - where change will be done.
> 3) If any of new names caches with any other cache name, an exception should
> be thrown. The most simple way: throw an exception if user-configured cache
> name starts with {{igfs-}} and ends with {{-meta}} or {{-data}}.
> Relevant code pieces:
> {{IgniteNamedInstance.initializeDefaultCacheConfiguration}}.
