Cassandra: Usage of Mapper

Akka Akka Streams & Alpakka

Hey guys,

I want to work with cassandra entities (based on annotation).
For that it exists a mapping manager, which is able to build a mapper for a annotated type:
com.datastax.driver.mapping.Mapper.
This mapper can be used to create statements directly. You don’t get a prepared statement.
If I look at the CassandraFlow API in Alpakka, then I don’t find any method which supports statements.
Is it possible to work with the mapper?
If not, it is planned?

Thank you and best
Sigurd

Hi,

we have a ticket that is tracking this feature request however there are no concrete plans to implement it in the near future. Would you be willing to take a look and possibly create a PR adding this feature?

Okay, thank you.
Is there any negative Performance impact if These Mapper is used?
