I agree that Manager is a term that is usually used for extensions of GridCacheManagerAdapter. Can we do the rename in other ignite issue? That's a personal question, we already have a chain of, like, 4 branches, created one from the other and they all have changes in this class. Renaming would be a nightmare :( ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
