Sam Tunnicliffe commented on CASSANDRA-12039:
---------------------------------------------
This sounds like a reasonable idea to me and as long as we provide a default,
no-op implementation of {{Index::getPostBootstrapTask}} it should be fine for
3.0.x IMO.
> Add a "post bootstrap task" to the index machinery

> Project: Cassandra
> Issue Type: New Feature

>
> Custom index implementations might need to be notified when the node finishes
> bootstrapping in order to execute some blocking tasks before the node itself
> goes into NORMAL state.
> This is a proposal to add such functionality, which should roughly require
> the following:
> 1) Add a {{getPostBootstrapTask}} callback to the {{Index}} interface.
> 2) Add an {{executePostBootstrapBlockingTasks}} method to
> {{SecondaryIndexManager}} calling into the previously mentioned callback.
> 3) Hook that into {{StorageService#joinTokenRing}}.
> Thoughts?
