What does enable=1 and priority=1 mean in ambari.repo? when I do `cat ambari.repo` I can see the last two rows showing `enable=1` and `priority=1`. What is the meaning behind that ?

From `man yum.conf`


enabled Either `1' or `0'. This tells yum whether or not use
this repository.

During depsolving, when choosing the
best provider among several, yum will respect the priority of
each provider's repository (note that there are other factors
which yum considers, which may overweigh the repository prior-
ity). The value is an integer from 1 to 99, 1 being the most
preferred repository, and 99 being the least preferred one. By
default all repositories have the priority of 80.
