> SQL engine optimizations for MultiDC
> ------------------------------------
>
> Key: IGNITE-26214
> URL: https://issues.apache.org/jira/browse/IGNITE-26214
> Project: Ignite
> Issue Type: Task
> Reporter: Sergey Chugunov
> Assignee: Aleksey Plekhanov
> Priority: Major
> Labels: IEP-140, ise
> Fix For: 2.18
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Document all places in SQL engine where operations could work suboptimal in
> MDC deployment: fulfilling requests from remote DC when the same data is
> available in local one.
> Evaluate approaches to fix that: from filtering nodes by DC to incapsulating
> DC awareness feature into affinity function so that these optimizations could
> be reused even in single DC installation (e.g. sending requests only to the
> same cell/server rack etc).
