Brief Summary

Since the end of June we defined the team OKRs for 2021-Q3, and work through them. These last week we were mostly focused on small improvements to the stability of the network, reliability of implementation, and improvements to documentation.

None

Action Items:

• nearcore
  • Publish near-account-id as an independent crate to be used throughout the ecosystem. (@miraclx) (blocked while waiting for refactor: Introduce strictly typed and assuredly validated AccountId #4440 review)
  • Work on getting reusable core crates (e.g near-primitives, near-crypto) lightweight and publishable (@miraclx)
  • Benchmark JSON-RPC performance in terms of requests per second (we focus on query method as others are considered as not very important to measure) (@khorolets)

    FT/NFT: make a research about them near-indexer-for-explorer#108
  • Introduce logic to stop retrying to store data after N attempts and report the situation somewhere we can find it and handle (@khorolets)

[MaksymZavershynskyi]

Btw, did we have any feature requests for streaming indexer or was it something that we decided to implement based on our own judgement?

[khorolets]

We haven't any feature requests especially in this regard. This streaming indexer idea came around after we've realised the pain of syncing data, dealing with backups, speaking with partners about mentioned pains. We thought that such indexer might decrease the pain.

So yeah, it's more like "based on our own judgement"

[frol]

We had a number of requests starting from #1996, and then almost every project out there requesting events or "TheGraph experience". The solution we have in mind (Kafka-based) does not involve huge investments on the implementation side, but we don't want to fall into providing services for free forever, so we want to dogfood NEAR economy model and test it with our current Indexer Framework partners (they struggle to maintain Indexer nodes themselves due to lack of resources).

[frol]

Here we go, one more explicit request: #4462 (comment)
