Reynold Xin updated SPARK-3019:
-------------------------------
Description:
The attached design doc proposes a standard interface for block transferring,
which will make future engineering of this functionality easier, allowing the
Spark community to provide alternative implementations.
Block transferring is a critical function in Spark. All of the following depend
on it:
* shuffle
* torrent broadcast
* block replication in BlockManager
* remote block reads for tasks scheduled without locality
was:
This is a ticket to track progress to have an internal interface for block
transfers (used in shuffles, broadcasts, as well as remote block reads for
tasks).
More details coming later.
