How do you browse them now? I am testing the Cassandra journal and I haven't found a way to browse them (however cumbersome-ly) yet.
I've tried with "select blobAsText(message)" and "select blobAsVarchar(message)" but that didn't work.
Thanks

You can either
- extend
CassandraJournalto additionally write JSON representations somewhere else - use
akka.persistence.PersistentViews to store JSON representations somewhere else or - try using akka-analytics to do whatever batch processing you need with Spark.

@artursoler I use a tool called DBeaver, the enterprise version (it's free even if it's enterprise) supports Cassandra and in the latest release they added support to show the contents of blob messages.
Edit: As a side note the developer also stated that in the future they might support custom deserializers for blobs: http://dbeaver.jkiss.org/forum/viewtopic.php?f=2&t=1734
@krasserm Hmmm... akka-analytics, never heard of that. I need to check that out.
