------------------------
Summary: Rya Accumulo performance can be improved
Key: RYA-535
URL: https://issues.apache.org/jira/browse/RYA-535
Project: Rya
Issue Type: Improvement
Components: dao
Affects Versions: 4.0.0
Reporter: Brad
Assignee: Brad
The Glowroot Java profiler found that for a fairly complex SPARQL query that
takes about 40 seconds to return, a huge 85% of the query time was spend in the
RangeBindingSetEntries class, doing the RangeBindingSetEntries#containsKey(Key)
function. Therefore optimising the performance of this method is critical to
overall Rya performance.
The very existence of this method, which relies on a O(n) lookup operation,
could potentially be refactored out by a small change to the way iterators are
returned from the DAO.
