> Project: Ignite
> Issue Type: Bug
> Components: thin client
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Priority: Major
> Labels: .NET, ignite-3
> Fix For: 3.0.0-beta2
>
>
> When *Table.ReadSchemaAsync* 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 *Task<ClientSchema>*, and
> use *GetOrAdd* to guarantee only one request for the given version. Make sure
> to handle failures - if a cached Task is failed, send a new request.
