Keep in mind that there are [automatic tags](https://puppet.com/docs/puppet/6.4/lang_tags.html) in exported resources
which can complicate things.
### Finding all instances of a deployed resource
Say you want to [deprecate cron](https://gitlab.torproject.org/tpo/tpa/team/-/issues/41303). You want to see where the `Cron`
resource is used to understand how hard of a problem this is.
This will show you the resource titles and how many instances of each
there are:
SELECT count(*),title FROM catalog_resources WHERE type = 'Cron' GROUP BY title ORDER by count(*) DESC;
Example output:
puppetdb=# SELECT count(*),title FROM catalog_resources WHERE type = 'Cron' GROUP BY title ORDER by count(*) DESC;
count | title

A more exhaustive list of each resource and where it's declared:
SELECT certname_id,type,title,file,line,tags FROM catalog_resources WHERE type = 'Cron';
Which host uses which resource:
SELECT certname,title FROM catalog_resources JOIN certnames ON certname_id=certnames.id WHERE type = 'Cron' ORDER BY certname;
Top 10 hosts using the resource:
puppetdb=# SELECT certname,count(title) FROM catalog_resources JOIN certnames ON certname_id=certnames.id WHERE type = 'Cron' GROUP BY certname ORDER BY count(title) DESC LIMIT 10;
