[ http://issues.apache.org/jira/browse/LUCENE-762?page=comments#action_12461460 ] Chuck Williams commented on LUCENE-762: ---------------------------------------
Hi Grant, Maybe even better would be to have an appropriate method on FieldSelectorResult. E.g.: FieldSelectorResult.readField(doc, fieldsStream, fi, binary, compressed, tokenized) This would eliminate the tests or map lookup in performance-critical code. > [PATCH] Efficiently retrieve sizes of field values > -------------------------------------------------- > > Key: LUCENE-762 > URL: http://issues.apache.org/jira/browse/LUCENE-762 > Project: Lucene - Java > Issue Type: New Feature > Components: Store > Affects Versions: 2.1 > Reporter: Chuck Williams > Assigned To: Grant Ingersoll > Priority: Minor > Attachments: SizeFieldSelector.patch > > > Sometimes an application would like to know how large a document is before > retrieving it. This can be important for memory management or choosing > between algorithms, especially in cases where documents might be very large. > This patch extends the existing FieldSelector mechanism with two new > FieldSelectorResults: SIZE and SIZE_AND_BREAK. SIZE creates fields on the > retrieved document that store field sizes instead of actual values. > SIZE_AND_BREAK is especially efficient if one field comprises the bulk of the > document size (e.g., the body field) and can thus be used as a reasonable > size approximation. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
