Subject [jira] [Commented] (OAK-4874) Improve the warning logged when traversal happens within property index
Date Mon, 03 Oct 2016 18:48:20 GMT

Alexander Klimetschek commented on OAK-4874:
--------------------------------------------

I would suggest "index walking" for #2. (Inspired from [traverse synonyms|http://www.thesaurus.com/browse/traverse?s=t])

> Currently a traversal related warning gets logged in 2 modes
> # Actual traversal - Query execution not backed by any index
> {noformat}
> LOG.warn("Traversed " + readCount + " nodes with filter " + filter + "; consider creating
an index or changing the query");
> {noformat}
> # Traversal within property index
> {noformat}
> LOG.warn("Traversed {} nodes ({} index entries) using index {} with filter {}", readCount,
intermediateNodeReadCount, indexName, filter);
> {noformat}
> To allow users to better distinguish between these 2 warning we should reword the warning
message in #2 to avoid using traversal there
