------------------------------------------
Summary: DirectoryTaxonomyReader should implement Accountable
Key: LUCENE-7972
URL: https://issues.apache.org/jira/browse/LUCENE-7972
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: master (8.0), 7.1
This class is a concrete instance of {{TaxonomyReader}} that uses a Lucene
index to map facet labels to ordinals.
It uses a fair amount of heap, e.g. to hold parent/sibling/child int arrays, to
cache recent lookups, and in the underlying {{IndexReader}}. I think we should
have it implement {{Accountable}} so people can track its heap usage.
