>             Project: James Server
>          Issue Type: Improvement
>          Components: cassandra, JMAP
>            Reporter: René Cordier
>            Assignee: Antoine Duprat
>            Priority: Major
>             Fix For: 3.10

>          Time Spent: 40m
>  Remaining Estimate: 0h

> h2. Why
> The cassandra table "thread_2" for storing thread data with the threadId guessing algorithm can grow significantly large over time. 
> An option for tiering data in that table after a certain amount of time should  provide useful in some use cases.
> h2. How
> Proposal is to add an optional TTL to the thread_2 table.
> In `jvm.properties`:
> {code:java}
> james.thread.window=90d
> {code}
> Default to none (keep forever)
> Document this in "tiering documentation".
> Note that "thread_lookup_3" needs to be kept for correctness (it's much smaller)
