I ran into an issue where I ran out of postgres disk space. I am using Docker with image graphprotocol/graph-node:v0.25.0. I’m otherwise doing what I perceive to be fairly tame operations saving data while running the node and being strict about what I’m saving. Further, my graph-node service and my postgres service are on different machines, and it’s the latter that ran out of disk.
My understanding is that I am streaming blocks as they come in, taking actions on them according to the subgraph’s .ts files, and then moving on. Is this wrong and my graph-node is actually indexing every block’s data while running this service? If so, is there a way to make that more sparse? I would expect that, once the node has read a block, that it would then move on to the next one and not save it. Where can I find information in the docs on what exactly is being saved by the graph node to postgres?
