Summary: Native kubernetes support for kylin streaming receivers
Key: KYLIN-4806
URL: https://issues.apache.org/jira/browse/KYLIN-4806
Project: Kylin
Issue Type: New Feature
Components: Real-time Streaming
Reporter: Xingxing Di
Currently kylin manually maintains stream receiver replicasets. Under this
design, when we have many cubes, we cannot achieve a perfect balance between
resource isolation and maintenance costs:
1. Maintain a large number of replicasets to maintain resource isolation, which
will cause a lot of maintenance costs
2. Maintain less replicasets to reduce maintenance costs, so one replicaset
should be used for multiple cubes, resource isolation will be a problem. eg:
One cube’s source data(Kafka topic) has grown abnormally, which may cause the
streaming receiver process unstable.
In the context of cloud native, kylin should add native support for kubernetes,
and then we can easily achieve *cube level streaming receiver cluster* (a set
of replicatset ) by define the necessary parameters such as parallelism, cpu,
memory, etc.
