> Change IndexEdge's props data type.

> Key: S2GRAPH-69
> URL: https://issues.apache.org/jira/browse/S2GRAPH-69
> Project: S2Graph
> Issue Type: Sub-task
> Reporter: DOYUNG YOON
> Assignee: DOYUNG YOON
> Labels: optimization, serde
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> User query traverse on IndexEdge, and current implemenation for deserialize
> bytes array into IndexEdge first(IndexEdgeDeserializable), then call
> IndexEdge#toEdge to create Edge class.
> I found out following parts copy data which is unnecessary.
> {noformat}
> props.map { case (k, v) => k -> InnerValLikeWithTs(v, version) }
> {noformat}
> This inefficiency exist because IndexEdge use Map[Byte, InnerValLike] and
> Edge use Map[Byte, InnerValLikeWithTs] as type of props value.
> It sounds like micro optimization but since this is called a lot, actually
> dependent on # fetched edges, I think improving this would create some
> changes on performance.
> To remove unnecessary copy, I am suggesting change type of IndexEdge's props
> same with Edge's props type Map[Byte, InnerValLikeWithTs].
