Zaoshi created TINKERPOP-2148:
---------------------------------
Summary: "no connection available!" is being thrown despite lots
of free connections
Key: TINKERPOP-2148
URL: https://issues.apache.org/jira/browse/TINKERPOP-2148
Project: TinkerPop
Issue Type: Bug
Components: dotnet, tinkergraph
Affects Versions: 3.4.0
Environment: Windows 10, C#, .NET Core, CosmosDB Graph
Reporter: Zaoshi
I am submitting multiple graph queries in parallel but in some cases it starts
throwing this exception:
{{Gremlin.Net.Driver.Exceptions.NoConnectionAvailableException : no connection
available!
at Gremlin.Net.Driver.ConnectionPool.GetAvailableConnectionAsync()
at Gremlin.Net.Driver.GremlinClient.SubmitAsync[T](RequestMessage
requestMessage)}}
When GremlinClient is initialized with {PoolSize = 1, MaxInProcessPerConnection
= 8} everything works fine, however, with {PoolSize = 8,
MaxInProcessPerConnection = 1} it starts throwing those exceptions even though
this connection pool should have same throughput. I have tried to increase pool
to {PoolSize = 128, MaxInProcessPerConnection = 1} but GremlinClient started to
fail even more.
