Andy Seaborne created JENA-352:
----------------------------------
Summary: Vast numbers of bNodes can overwhelm the parser
Key: JENA-352
URL: https://issues.apache.org/jira/browse/JENA-352
Project: Apache Jena
Issue Type: Bug
Components: RIOT, TDB
Reporter: Andy Seaborne
Priority: Minor
The parsers need to keep a bNode label to bNode map which (unusual data) can
grow too large. As it takes unusual data, rated as "minor".
outline of solution:
1/ which to a bNode allocation scheme which is a large random number per file,
and concat or XOR with the claimed bNode label to generate a unique label
without state build up.
2/ (Turtle) don't remember [] bnodes past their usage scope.
3/ Partial - keep a sliding window of bNodes label amppings
