Note

London, UK - July 25th, 2018 - Lenses v2.1 is now generally available

New

• Topology View for your apps (Kstream, Spark, Akka) and microservices.

• Schema Registry support for HortonWorks Schema Registry
• Global Kerberos Single Sign-On support
• New UX: View Kubernetes pods logs
• New UX: On a topic you can now delete partition data up to a given offset
• The dependency on Zookeeper is not mandatory anymore. This makes it easier to run Lenses in cloud.

Improvements

• Allow Inserting messages in AVRO topics with union and logical types, enum and null
• SQL - improved decoder validation on joins
• SQL - push down filter predicates in joins. This avoids streaming records that are not part of the join
• SQL - supporting any AVRO union of (X,Y,Z) - types. We do not advocate for such AVRO constructs though.
• SQL - allow group aggregations over a key field on OUTER joins. i.e. FROM left outer join right ON left.fieldA = right.fieldX GROUP BY tumble/hop/session/slide, _key

Fixes

Thanks to a vibrant community and our clients multiple improvements are beyond the scope of the release notes.
