--------------------------------------
Reviewers: Chris Lohfink
> Scheduled tasks in management process
> -------------------------------------
>
> Key: CASSANDRA-15023
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15023
> Project: Cassandra
> Issue Type: Sub-task
> Components: Tool/nodetool
> Reporter: Vinay Chella
> Assignee: Vinay Chella
> Priority: Normal
> Labels: sidecar
>
> Scheduled tasks in a management process operate some task on a periodic or
> scheduled basis (e.g. periodic cleanups, compactions, flushes, backups etc…).
> We propose pluggable scheduled jobs which allow users to achieve simple yet
> powerful operations activities that are frequently required in Cassandra.
> Basically, these are cron jobs.
> *Proposed Scope*
> * _GET /v1/scheduled/node_: Shows the scheduled tasks that run on the local
> host by the sidecar. These are determined via the configuration of the
> management process.
> * _Cleanup_ of tables (nodetool cleanup) in Cassandra will be implemented as
> part of this JIRA. This maintenance activity is an important task when your
> environment is prone to lose nodes and move nodes all the time. Having
> {{cleanup}} activity scheduled on a regular basis helps to maintain the
> fidelity of the database.
