Change Summary

The changes in this release include bug fixes and infrastructure improvements only - see next section.

Notable Bug Fixes and Improvements

  1. Data center synchronization improvement. The data transfer that is managed during sync now switches automatically among 3 different modes: consume, bulk-consume and slow-bulk, depending on environment conditions.
  2. Improved resilience of the background process that writes data in the new format. Tasks are now transferred seamlessly among machines if a machine goes offline or comes back online.
  3. Bug fix #285: Some whole-graph SPARQL queries timed out due to errors in the optimization logic. Here is an example of a query that timed out:

    SELECT ?x ?name WHERE { ?typebridge metadata:geographyType data:1-308005 . ?x metadata:geographyType ?typebridge . ?x metadata:geographyUniqueName ?name . }

  4. Bug fix #292: Due to an error in caching, CM-Well would sometimes return the "pending" response when under stress.
