Sorry for the delay @cattania many of us were out for the holidays. I will start on this in the next day or two.

Hi @cattania, thanks for the delivery. I am testing hyperdot.xyz at the moment, and I'm not able to get any queries to work. For example, select * from bigquery-public-data.crypto_polkadot.accountreference0 where block_number > 18900000 results in popups "I is undefined" and "http error" and in the console I get a 504 error. Can you advise?

Hi @semuelle , thanks for reply, We checked that the service queries on the backend were working, and finally we found out that because we're using Cloudflare proxies, the select * from bigquery-public-data.crypto_polkadot.accountreference0 where block_number > 18900000 running needs to process a lot of data, so it takes a while to run, in fact it takes about 1m21s to process. But Cloudflare closes the connection by default after 60s.

We've adjusted the infrastructure so that's not a problem now.

For queries, since the on-chain data of the index is huge and our server has limited resources, we recommend adding some condition for filtering and adding limit to limit the size of the data returned, for example select * from bigquery-public-data.crypto_polkadot.accountreference0 where block_number > 18900000 limit 100
