Eventsbytag1 materialized view

Lagom
1

Hi all,

What’s the purpose of eventsbytag1 materialized view in Lagom?
If it is not mandatory to have this, is there a way to configure so that this does not get created?

A materialized view is marked as experimental in the Cassandra community and it is causing unnecessary noise in our logging system.

Thanks,

Joo

Hi @lejoow,

the eventsbytag1 view is used by the EventsByTag query (part of the Akka Persistence Queries) in akka-persistence-cassandra. The use of Cassandra Materialized Views was replaced in latest versions of akka-persistence-cassandra but Lagom hasn’t upgraded yet.

Cheers,

Hi @mm,

we aim to bump akka-persistence-cassandra dependency in Lagom 1.6.
