rvesse opened a new pull request, #1641: URL: https://github.com/apache/jena/pull/1641
When the primary index is G??? based use distinctAdjacent() rather than distinct() when listing graph nodes for TDB 2. This provides some speedup and a constant memory footprint for this iteration as we only have to remember the previous graph name not all the graph names. This partially addresses #1639, in my testing it yields about a 20% speed up on some synthetic test datasets. ---- By submitting this pull request, I acknowledge that I am making a contribution to the Apache Software Foundation under the terms and conditions of the [Contributor's Agreement](https://www.apache.org/licenses/contributor-agreements.html). -- This is an automated message from the Apache Git Service.
