[Bug] IPFS block data is consuming 80% of the storage space

Bug report

I'm currently hosting my own graph-node on AWS EC2, and I've noticed that the IPFS block files are growing incredibly fast, taking up about 100 GB at the moment (while PostgreSQL is using only 28 GB). It seems like the graph-node is just seeding for the IPFS network, and I'd like to figure out how to stop that.

This is mydocker-compose.yml.

version: '3'
services:
  graph-node:
    image: graphprotocol/graph-node
    ports:
      - '8000:8000'
      - '8001:8001'
      - '8020:8020'
      - '8030:8030'
      - '8040:8040'
    depends_on:
      - ipfs
      - postgres
    extra_hosts:
      - host.docker.internal:host-gateway
    environment:
      postgres_host: postgres

Linux

Begin with the supplied docker-compose.yml, especially the ipfs service, its Kubo image, and the ./data/ipfs volume. Trace how graph-node uses that IPFS endpoint and determine whether supported configuration can prevent unbounded block growth without breaking required content retrieval; done means documenting or implementing a verified mitigation and its storage trade-offs.
