Multipart Block-put for multiple block injection

[hsanjuan]

Version information: master

Type: enhancement

Description:

I would like to have a "streaming" block-put where I can send many blocks on a single request to the block/put http endpoint. I don't think this works right now (correct me if I missed it).

Ideally the happy path is to translate this into a nicely buffered and optimized PutMany() so that, when ingesting many blocks via the API, there is a significant performance gain vs injecting one by one.

I agree. We'll have to make sure to use EmitOnce when only putting one block for compatibility with js-ipfs but that's not that bad.

The only interesting thing here is that the current block API in the core API doesn't support batch put. See: ipfs/interface-go-ipfs-core#31.
