--------------------------------------------------------------
DataSource now implements Externalizable (and Serializable as well), but there
is one limitation. DataSource is only partially serialises its Cassandra
connection options. Here is the list of DataSource connection options which
will not be serialized/deserialized:
- LoadBalancingPolicy
- ReconnectionPolicy
- RetryPolicy
- AddressTranslator
- SpeculativeExecutionPolicy
- AuthProvider
- SslOptions
- PoolingOptions
- SocketOptions
- NettyOptions
*The main reason - corresponding Cassandra interfaces doesn't extend
Serializable.*
Workaround:
1) Implement your own wrapper, above corresponding Cassandra connection option
specific implementation which you are going to use (TokenAwarePolicy,
RoundRobinPolicy and etc.)
2) Wrapper should also implement Externalizable - there you should put all your
custom serialization/deserialization logic
3) In the such case, DataSource will detect that corresponding connection
option object implements Serializable and it will be used during DataSource
serialization/deserialization

> Project: Ignite
> Issue Type: Sub-task
> Components: cache
> Reporter: Igor Rudyak
> Assignee: Igor Rudyak
> Priority: Minor
> Fix For: 1.8

>
> Current implementation of
> org.apache.ignite.cache.store.cassandra.utils.datasource.DataSource doesn't
> implement Serializable, thus for distributed Ignite clusters,
> CassandraCacheStoreFactory could only be setup through Spring XML file, but
> not from code.
> New version of
> org.apache.ignite.cache.store.cassandra.utils.datasource.DataSource should
> implement Serializable
