Subject Applicability of term 'cache' to Apache Ignite
Date Mon, 15 Oct 2018 11:49:11 GMT
Hi Igniters,

I would like to rise a question how we use the term *'cache'* in Ignite and
how it corresponds to terminology in IT industry in general.

>From wikipedia:
In computing <https://en.wikipedia.org/wiki/Computing>, a *cache* /kæʃ/
<https://en.wikipedia.org/wiki/Help:IPA/English> *kash*
<https://en.wikipedia.org/wiki/Help:Pronunciation_respelling_key>, is a
hardware or software component that stores data so that future requests for
that data can be served faster; the data stored in a cache might be the
result of an earlier computation or a copy of data stored elsewhere. [1]

When the first version of Ignite was released, this term was correct. We
positioned Ignite mostly as an intermediate storage layer between
application and a database, designed to make data access faster.

However, since addition of native persistence we started to call Ignite a
"memory-centric database", and as far as I know, some organizations now use
it as a primary data storage, without underlying database. In this case,
calling our storage unit a *'cache'* causes unnecessary confusion.

Thus, I suggest to rename IgniteCache in Ignite 3.0 to something that would
fit both use-cases.
Personally I like the term IgniteSpace.
