Ziqi Liu updated SPARK-42980:
-----------------------------
Summary: lightweight Broadcast implementation (was: SmallBroadcast)
> lightweight Broadcast implementation
> ------------------------------------
>
> Key: SPARK-42980
> URL: https://issues.apache.org/jira/browse/SPARK-42980
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 3.4.0
> Reporter: Ziqi Liu
> Priority: Major
>
> The current TorrentBroadcast implementation is originally designed for large
> data transmission where driver might become the bottleneck and memory might
> also be the concern. Therefore it's kind of heavy and comes with some fixed
> overhead:
> * torrent protocol: more round traffic
> * disk level persistency, BlockManager, extra overhead
> which makes it inefficient for some small data transmission.
> We can have a lightweight broadcast implementation, e.g, SmallBroadcast,
> which implement star-topology broadcast(which avoids the unnecessary round
> traffic), and maybe in-memory only.
