How to enable GC?

[johngcrowley]

Setup: Running Neon locally via docker
Note: not the docker-compose quickstart. Supplying config values to Neon and Neon compute node containers.

What works:

• supplied my own GCS bucket configuration to pageserver.toml
• supplied a [tenant_config] to .neon/tenants/<tenant_id>/config with gc_horizon, gc_period, pitr_interval values.
• have Pageserver, 3 Safekeeper, Storage Broker and Compute node running well, pushing / pulling to GCP bucket.

What doesn't:

• data files keep piling up under .neon/tenants/<tenant_id>/. Nothing removes them. Tried setting pitr_interval, gc_period, and gc_horizon low, as noted here
• I added a [disk_usage_based_eviction] to my pageserver.toml file as well, but nothing gets resolved.
• PageServer keeps filling up and crashing after large inserts.

Needs:

• how to configure GC to work?
• know the difference between GC and the disk_usage_based_eviction feature?

I am loving this product and have gratitude for this software. I want to be able to run it in production environment.
