--------------------------------------------------------------
Alexey,
Mutations is rather internal feature - to accumulate all the changes made
inside transaction. Users never interact with mutations directly - they just
call *put/putAll/remove/removeAll* methods of Ignite cache and all required
mutation objects will be created inside CassandraCacheStore implementation (if
you are using *TRANSACTIONAL* caches).
Thus, I don't think that it makes sense to document mutations on readme.io
cause it's rather internal feature. However, it makes sense to add
documentation providing more details about how changes made inside Ignite
transactions will be persisted into Cassandra. I am going to add this
documentation a bit later.
