Denis Magda commented on IGNITE-946:
------------------------------------
Valentin, several questions/thoughts so far cause the task is not fully clear
for now.
1) Do you mean {{GridCacheVersionedEntry}} interface under "versioned entry"?
This interface is implemented by two classes that are used by DR only.
If you mean this interface, then I would better introduce another interface
{{VersionedEntry}} that will have only those methods that should be in public
API.
{{GridCacheVersionedEntry}} is kind of DR-oriented mess.
{{GridCacheVersionedEntry}} will extend {{VersionedEntry}} and will be kept
internal.
2) From your description I see that it will be useful to make version
information public. Why do we need to make {{GridCacheVersionedEntry}} public
then? Why can't we make {{GridCacheVersion}} public instead?
My design view is the following:
- adding {{CacheVersion}} class that will have the same public API methods as
{{GridCacheVersion}} has excluding DR-oriented. {{GridCacheVersion}} will
extend {{CacheVersion}};
- adding, if needed, {{VersionedEntry}} that will return {{CacheVersion}}.
{{GridCacheVersionedEntry}} should be refactored cause in reality it's a DR
cache entry version.
Thoughts?
