Work Description: srfrnk commented on issue #8090: [BEAM-6861] Select
fields and computed fields in CassandraIO.Read
URL: https://github.com/apache/beam/pull/8090#issuecomment-474942509
Sorry for barging in on this.
If there is a need for a more robust query building mechanism we might
consider using [Datastux
QueryBuilder](https://docs.datastax.com/en/drivers/java/2.0/com/datastax/driver/core/querybuilder/QueryBuilder.html).
I tryed to go for that approach when I added `withWhere` but since their
classes are not `Serializable` I could not.
I attempted to fix this problem
[here](https://github.com/datastax/java-driver/pull/1163) but it was rejected.
Maybe with enough influence we can manage to make the change?
If not maybe this repo can be forked into Beam and so a working QueryBuilder
can be used without having to rebuild it?
WDYT?
