             Summary: .NET: Thin 3.0: Same schema version is retrieved multiple times in concurrent scenarios
                 Key: IGNITE-19355
                 URL: https://issues.apache.org/jira/browse/IGNITE-19355
             Project: Ignite
          Issue Type: Bug
          Components: thin client
            Reporter: Pavel Tupitsyn
            Assignee: Pavel Tupitsyn
             Fix For: 3.0.0-beta2


When *ClientTable.getSchema* is called, we send a request for the given schema version every time, even if another request for that version is active (e.g. in case of multiple concurrent TUPLE_GET requests).

Instead of caching *ClientSchema*, we should cache *CompletableFuture<ClientSchema>*, and use *computeIfAbsent* to guarantee only one request for the given version. Make sure to handle failures - if a cached future is failed, send a new request.
