-----------------------------------------
[~ilyak] hi! I'm working on this task and have a question about introducing
alias (you mention in the comment above).
Looks like introducing the alias should be a separate activity and discussed
more carefully. As I understand there are 2 places where the mode is set from
String:
* *spring configuration* injects the value by field name of the enum
_CacheAtomicityMode_;
* in method *GridSqlQueryParser.processExtraParam* where ** we set the value
manually.
If it's required to support MVCC alias in Spring Configuration out of the box
then CacheAtomicityMode class should a line:
{code:java}
/**
* An alias for TRANSACTIONAL_SNAPSHOT mode.
*/
public static final CacheAtomicityMode MVCC = TRANSACTIONAL_SNAPSHOT;
{code}
In that case it will be correctly parsed by Spring, also there will be
interchangeability of this modes out of the box. But it breaks common enum
functionality (valueOf(), values()).
Should we continue discussing that within this task?
