Issue reported on the forum: http://www.openrdf.org/forum/mvnforum/viewthread?thread=1466
NativeStore.getContextIDs() currently stores all returned resources in a HashSet to filter duplicates. When the stores contains large numbers of contexts, this consumes large amounts of memory. In case a context-first index is available, this can be optimized by iterating over the triples in order, requiring only the last returned resources to be remembered.
|
|
Add context iteration methods to TripeStore and NativeStore that are optimized if an index starting with 'c' exists in revision 7430.

Optimize NativeStore.getContextIDs() to use context-first indexes if possible
