Zipkin 2.11 dramatically improves Cassandra 3 indexing and fixes some UI glitches

Cassandra 3 indexing

We've had cassandra3 storage type for a while, which uses SASI indexing. One thing @Mobel123 noticed was particular high disk usage for indexing tags. This resulted in upstream work in cassandra to introduce a new indexing option which results in 20x performance for the type of indexing we use.

See #1948 for details, but here are the notes:

  1. You must upgrade to Cassandra 3.11.3 or higher first
  2. Choose a path for dealing with the old indexes
  • easiest is re-create your keyspace (which will drop trace data)
  • advanced users can run zipkin2-schema-indexes.cql, which will leave the data alone but recreate the index
  1. Update your zipkin servers to latest patch (2.11.1+)

Any questions, find us on gitter!

Thanks very much @michaelsembwever for championing this, and @llinder for review and testing this before release. Thanks also to the Apache Cassandra project for accepting this feature as it is of dramatic help!

UI fixes

@zeagord fixed bugs relating to custom time queries. @drolando helped make messages a little less scary when search is disabled. Zipkin's UI is a bit smaller as we've updated some javascript infra which minimizes better. This should reduce initial load times. Thanks tons for all the volunteering here!
