Graham Triggs resolved DS-739. ------------------------------ Resolution: Fixed > Improve performance of Lucene indexing > -------------------------------------- > > Key: DS-739 > URL: https://jira.duraspace.org/browse/DS-739 > Project: DSpace > Issue Type: Improvement > Reporter: Graham Triggs > Assignee: Graham Triggs > Fix For: 1.7.0 > > > Adds a batch processing mode for Lucene indexes. > Can be controlled by calling DSIndexer.setBatchProcessingMode(boolean). > NB: If you set batch processing mode to true, ensure that you set it to > 'false' at the end of the batch to flush any unwritten documents. > The size of the batch can be controlled by setting a numeric value in > dspace.cfg for the property: search.batch.documents > By default, the size of the batch is 20 documents. > Additionally, there is the possibility to create a 'delayed index flusher'. > If a web application pushes multiple search requests (ie. a barrage or sword > deposits, or multiple quick edits in the ui), then this will combine them > into a single index update (up to the limit of the batch defined above). > To use the delayed update, set the property 'search.index.delay' in > dspace.cfg to the number of milliseconds to wait for an update. eg. > search.index.delay = 5000 > will hold a Lucene update in a queue for up to 5 seconds. After 5 seconds - > or the batch limit above is reached - all waiting updates will be written to > the Lucene index. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.duraspace.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------------ Centralized Desktop Delivery: Dell and VMware Reference Architecture Simplifying enterprise desktop deployment and management using Dell EqualLogic storage and VMware View: A highly scalable, end-to-end client virtualization framework.
