We are using aerospike server of version 184.108.40.206 in production on AWS front-ended by AWS Lambda APIs in Python.
We use aerospike python client in AWS Lambda, to connect to the server. What we are seeing is that a decent majority of requests are having the errors of “ClientError: (-1L, ‘Failed to seed cluster’, ‘src/main/aerospike/as_cluster.c’, 417)”. The server is working fine, I see this errors after one second of trying to connect to the server. We receive a good number of requests and we try to connect to the server for every request.
Questions in this regard:
- The server health is fine. Any specific reasons for this error, and possible to avert the same ? Our timeout is 5 seconds, yet get this error just after a second. Is it that we are crossing a limit anywhere ?
- We are seeing good amount of CPU spikes in the server for a tps of 500. Is it because of constant connections creation for every API call.
- If the answer to 2) is yes, then can we create a connection upfront and use it for subsequent requests as well in AWS lambda ? Also what would be the lifetime a request can live if this the case?
Please let me know if you need anything else from our end.
