I mean CACHE from InterSystems (http://www.intersystems.com/cache/)
Does this database stable enough ? Does the vendor provide prompt support for issues and bugs ? Will the database files grow faster (comparing with the same amount of data in traditional RDBMS) ?
I would like to read an opinion of a DBA who have ever managed a CACHE database and also had in the past an experience with an enterprise version of any traditional RDBMS (like MS SQL, Oracle, DB2). Were your daily DBA tasks very different and what was your biggest challenge with that ?
I will also appreciate if one can share an opinion of how CACHE from InterSystems can be compared with other object-oriented database management systems (OODBMS)
