Starting in 9.0.0, this client is configured to not time out any HTTP request by default. {{es}} will always eventually respond to any request, even if it takes several minutes. Reissuing a request that it has not responded to yet can cause performance side effects. See the official {{es}} recommendations for HTTP clients for more information.
Prior to 9.0, this client was configured by default to operate like many HTTP client libraries do, by using a relatively short (30 second) timeout on all requests sent to {{es}}, raising a TimeoutError when that time period elapsed without receiving a response.
If your circumstances require you to set timeouts on Elasticsearch requests, setting the requestTimeout value to a millisecond value will cause this client to operate as it did prior to 9.0.
