------------------------------------
Summary: SortingStoredFieldsConsumer should use a format that has
better random-access
Key: LUCENE-9510
URL: https://issues.apache.org/jira/browse/LUCENE-9510
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
We noticed some indexing rate regressions in Elasticsearch after upgrading to a
new Lucene snapshot. This is due to the fact that SortingStoredFieldsConsumer
is using the default codec to write stored fields on flush. Compression doesn't
matter much for this case since these are temporary files that get removed on
flush after the segment is sorted anyway so we could switch to a format that
has faster random access.
