don't index the whole chain

[rajgoesout]

I first indexed using -indexhead flag, which didn't take much time, but the -indexhistory seems to take a really long time given that I am indexing the nerpa devnet. I also see that some tables like actors, actor_states, chain_visualizer_blocks_view, etc are getting filled, but tables like miner_infos, miner_sector_infos, etc are empty.

From what I understand, visor will first fill up all the chain data (from genesis), and after that, fill up the miner tables. Is that correct? Is it possible to index only a certain timespan (eg: last/first 5000 epochs), and fill all the tables (like miner info) for that much chain data?

Hi, We recently add a new command called "walk" which should work better for you.

You can run it like this to index miner states:

visor walk --from 1000 --to 2000 --tasks=actorstatesminer 

You can include multiple tasks by comma separating them. The full list is here https://github.com/filecoin-project/sentinel-visor/blob/master/chain/indexer.go#L23
