>             Project: Sidecar for Apache Cassandra
>          Issue Type: Improvement
>          Components: Configuration, Rest API

> I would like to propose the following enhancements for the Cluster Lease 
> Claim feature in Sidecar:
> - Handle IllegalArgumentException thrown when resultSet doesn't contain owner 
> information. This is happening seldom times but it is noticeable. The source 
> of the issue seems to indicate an issue in the driver or Cassandra codebase. 
> I am able to reproduce the issue by running Sidecar locally for a long time. 
> However, there's no good way to reproduce it in a test.
> -  Better defaults for cluster lease task: Reduce the cluster lease task 
> execution frequency to reduce the potential for CAS contention on the 
> sidecar_internal.cluster_lease_v1 table in Cassandra.
> - Introduce randomized delay when scheduling ClusterLeaseClaimTask: to reduce 
> potential races when all instances are trying to acquire the lease at the 
> same time
> - Add new strategy to select the number of participants for the cluster 
> lease: This is to prevent too many participants trying to acquire the lease 
> for clusters with user keyspaces that are highly replicated.
