NFT indexing time

Technical Issue Reporting
#1

I am evaluating Moralis for an internal service that tracks NFT transfers by block. I am finding that while most blocks are indexed in seconds, some blocks do not get indexed in a reasonable time. Some blocks are still not indexed after an hour or more.

What is the expected block indexing latency for NFT transfers?

#2

Let us know if you see some concrete example next time

We have 10-30 second index time

#3

Block 14027028 is around 12 hours old and still not indexed as of 9:50AM CST:

$ curl “https://deep-index.moralis.io/api/v2/block/14027028/nft/transfers” --header “X-API-Key: xxxx”
{“total”:0,“page”:0,“page_size”:500,“cursor”:"",“result”:[],“index_complete”:false,“block_exists”:true}

#4

how do you know that there were NFT transactions in that block?

#5

I don’t know, that’s why I’m calling the API. Are you saying that “index_complete” will remain “false” for blocks that do not contain NFT transfers?

How would I determine the difference between a block that has not been indexed yet and one that will never be indexed in that case?

#6

Could someone please confirm whether blocks which have no NFT transfers permanently have “index_complete”:false?

And if so, is there a way to determine whether a block has no NFTs vs. has not completed indexing?

Thank you.

I will get back when I have the answer

it looks like there were some problems with that specific block, now this is the output:

{
  "total": 0,
  "page": 0,
  "page_size": 500,
  "cursor": "",
  "result": [],
  "index_complete": true,
  "block_exists": true
}

meaning that it should be "index_complete": true when it was processed even if it doesn’t have any NFT transfers
