And I think we need some CI . Besides, I suggest changing the status of the output from a simple boolean value to some status value string, such as: INIT, PROCESSING, FAILED,SUCCESS. The states that can be expressed may be a little more than simple Boolean, and it is more general.

There are various scenarios in that the caller may need to > probe the status again: > * The caller times out > * It is not possible to keep the caller hanging for such a long time > And If the caller does not know what happened internally, then it cannot > retry, etc., leading to other issues. > So, in this ticket, I am going to add a new nodetool/JMX command that can be > invoked by the caller anytime, and it will return the correct status. > It might look like a smaller change, but when we need to operate Cassandra at > scale in a large-scale fleet, then this becomes a bottleneck and require > constant operator intervention. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
