Question: What's the purpose of the "bitcore-node.db" folder? #1409

Closed LAMike310 closed 8 years ago

LAMike310 commented 8 years ago

So I was planning to put the bitcore project on a 128gb USB drive, but then I realized my folder was 168GB. so I looked into each folder and saw that the "bitcore-node.db" folder had 88GB inside of it.

I deleted the "bitcore-node.db" folder and started up the node again, and everything seemed to work. It did create a new "bitcore-node.db" folder with a few files in it, but I couldn't open any of them on my Mac. (.idb file extension).

Just curious why this folder is needed? And will I be ok if I delete this folder every few weeks in case it gets too big?

Thanks, Mike

If you're running bitcore v4 (and bitcore-node v3), the bitcore-node.db folder is no longer necessary, and can be removed, as detailed in upgrade docs: https://github.com/bitpay/bitcore-node/blob/master/docs/upgrade.md.

If you're running bitcore v3 (and bitcore-node v2), the directory is important and should not be removed. The files in it are for leveldb for the various additional indexes.

BTW, the prerequisites list ~200GB with ~8GB of RAM now: https://github.com/bitpay/bitcore-node#prerequisites

Got it, so if I upgrade to 4.0, I'll be able to get rid of the bitcore-node.db folder, but the node won't be able to fit on a 128gb drive. Maybe I'll have to upgrade to a 256GB. Are there any plans to create a node that takes up less hard drive space? 200GB could be a big commitment for a hobby project to some developers, especially if they don't have a great internet connection.

Do you think running it off of this card would cause problems?

Thanks for your advice!

You can run Bitcoin Core pruned. However the Bitcore build with address indexes doesn't support prunning while address index is enabled currently. I spawned an issue (https://github.com/bitpay/bitcoin/issues/19) regarding that (though I do not know if/when would be planned to be implemented).

I don't have any experience with that flash card to give any input there. I think this question has been answered at this point. Let us know if you have any issues.
