-----------------------------------
Summary: Dataset#listNames slow for large TDB2 datasets
Key: JENA-1769
URL: https://issues.apache.org/jira/browse/JENA-1769
Project: Apache Jena
Issue Type: Bug
Components: TDB2
Affects Versions: Jena 3.13.0
Reporter: Damien Obrist
With Jena 3.13.0, the running time of {{Dataset#listNames}} has increased
significantly for TDB2 datasets.
I have compared the running times for a sample TDB2 dataset containing
*1'000'000 triples*. I have observed a running time of *~270ms* with Jena
3.12.0 and *~13.5s* with Jena 3.13.0.
We're using a dataset with many millions of triples and for our use case, the
running time has increased from seconds to minutes.
