possible hang in insert

[idobenamram]

we encountered a couple of hangs in our bigquery task which inserts to bigquery tables, we think the problem is a known bug in hyper which is the underlying way to send http in reqwest (hyperium/hyper#2312). there is also a mentioned simple fix. we have encountered this bug in several other places in our codebase.

Did using the workaround you mentioned in your second link (pool_max_idle_per_host(0)) actually resolve the problem?

[idobenamram]

we can't say for sure, but because of previous debugging that we did and multiple times it happened we strongly believe it this. ill link an issue i opened to another crate where we thought the hang was in the beginning it contains a lot of info
udoprog/leaky-bucket#35

@idobenamram Have you deployed a modified version of this library (gcp-bq-client) with the aforementioned fix? If so, did it indeed resolve the insertion blocking over a significant period?
