Kapacitor 0.11 RC has been released with significant performance gains, exposing internal metrics and a simplified API for working with functions from InfluxQL. Kapacitor is now up to 4x faster in some cases, allowing users to right-size their instance more accurately. The new release also introduces improved functionality, such as the ability to communicate with multiple InfluxDB clusters and simplify TICKscript usage. With these changes, Kapacitor can act as a Continuous Query engine between different InfluxDB clusters, providing enhanced capabilities for data processing and alert management.
