Cassandra and Hector = MultiGetSliceQuery, with Column-Values of various different types?

Hallo,

I do not understand, how to query cassandra with hector, but the column-values returned are not of one single type, but of many:

I put in ???? where I do not know what to do:

MultigetSliceQuery<String, String, ??????> multigetSliceQuery = HFactory.createMultigetSliceQuery(keyspace, stringSerializer, stringSerializer, ???????);

For for example, if all my column-values are of String type, I would put in String. But I have differnt ones like String, Integer, and byte[] in one single row. So I must pass in more then one Serializer.

How to solve this?

Thank you.

(can one pls create hector as tag? I am not allowed to do this)

Solution

  • You can use the ByteBufferSerializer, and then convert the ByteBuffers returned from ByteBufferSerializer as the argument to StringSerializer and IntegerSerializer to convert the columns which are Strings and Integers.
