[jira] [Commented] (IGNITE-3609) Utilize Cassandra logged batches for transactions

    [ https://issues.apache.org/jira/browse/IGNITE-3609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15524978#comment-15524978 ] 

Alexey Kuznetsov commented on IGNITE-3609:
------------------------------------------

Igor, I reviewed PR and have several questions:
 1) Method *org.apache.ignite.cache.store.cassandra.persistence.PojoValueField#init* has commented body. Looks like a bug.
 2) In Method *CassandraHelper.isTableAbsenceError* entry.getValue() evaluated several times, may be declare a variable?
 3) CassandraSessionImpl, CassandraCacheStore, CassandraDirectPersistenceTest and TestsHelper contains imports with wildcards. In Ignite we are not using wildcard imports. Please fix.
 4) Class TestTransaction does not have javadoc and Apache license header.
 5) CassandraLocalServer does not have Apache license header.

Also could you describe mutations? How they work? Do you have a test for them?
