Hi Kenan, Either your *examples.cassandra_persistence_store.model.TestResponse* implementation is incorrect or you just accidentally inserting incorrect values into your Cassandra table. Here are the details: 1) *col5* field in *TestResponse* class has *long* type - which means that it's not

Hi, You can store enum field as a blob using Cassandra module for Ignite, but you should manually specify this in your persistence descriptor. Igor On Jul 14, 2017 12:25 AM, "babak" wrote: > hi, > > I have a model with enum field. I insert the model to the ignite

Hi Roger, You can use Ignite-Cassandra integration module. In case you need to load specific portion of you Cassandra dataset into Ignite you can use *loadCache(...)* method of Ignite cache API, providing it appropriate CQL query. Igor On Tue, Jul 11, 2017 at 8:29 PM, Roger Fischer (CW)

Hi Riccardo, It depends on how you are asking for the record which is not in Ignite cache. If you are doing this using *get* method of Ignite cache API it will load this record from DB (if it's not already in Ignite cache), put it into in-memory cache and return it to you. But if you are using

Re: Cassandra Cache Store Example

and Ignite partitions are two absolutely different animals, it doesn't make sense to compare them. Just check that you are using @AffinityKeyMapped annotation for your key classes.
