---------------------------------------------------
There are two parts to the unified scheduler.
*1. Enabling scheduler (controlled through yaml/nodetool)*
!image-2024-11-20-20-31-58-343.png|width=200,height=150!
*2. Table-level CQL property*
!image-2024-11-20-20-31-45-813.png|width=200,height=150!
#1 is, by default, disabled, and it requires opt-in. If #1 is disabled, then #2
is immaterial; repair will not happen.
Now, if #1 is enabled, #2 will decide whether to repair a particular table.
Today, #2 has all tables enabled.
So, as part of this ticket, we want to disable system_trace.* tables. i.e.,
system_trace.* tables CQL property after this ticket would look as follows:
{code:java}
desc system_traces.sessions;
....
....
....
AND repair_full = {'enabled': 'false'}
AND repair_incremental = {'enabled': 'false'} {code}
> Disable repair on system_traces.* tables by default

> Since _system_traces_ table does not contain the important information,
> running repair is not necessary. By default, disable repair on this system
> table.
