HA CEP reference implementation was designed and supported with AMQ Streams 1.x (Strimzi in community). However, AMQ Streams 1.x are end of life since end of January. See https://access.redhat.com/support/policy/updates/jboss_notes/#p_Streams .

This means some investigation and probably non-trivial changes would be need to make this running on new major version of AMQ Streams 2.0. It may be on multiple sides like engineering, QE and also documentation. There was also no BAPL request for support of AMQ Streams 2.0.

Therefore I'm proposing to end the support for HA CEP reference implementation due to end of life of AMQ Streams 1.x.
