> We need to optimise our Message storage.
> Currently, reading messages even with FetchType.Metadata is very inefficient, as Blob is stored with the data. This makes IMAP requests like *UID FETCH 1:\* UID* very inefficient and actually overload the cluster.
> This task should write a new CassandraMessageDaoV2 that stores streamable blobs in a separate table.
> Introduce you DAO on the top of:
>  - A new table for messages
>  - A new table for blobs
>  - A new table for blobParts
> Make CassandraMessage\*Mapper:
>  - Write to CassandraMessageDaoV2
>  - READ from CassandraMessageDaoV2 and if not found, READ from CassandraMessageDaoV1
> When reading from CassandraMessageDaoV1, you should take care to to *on the fly* migration:
>  - Read from CassandraMessageDaoV1
>  - Write in CassandraMessageDaoV2
>  - (Delete for space concerns) from CassandraMessageDaoV1
