Dear PSC members,
Proposal to apply performance enhancements to GeoNetwork trunk (2.5 Unstable) for supporting larger catalogs (10s or 100s of thousands of records) is available at:
http://trac.osgeo.org/geonetwork/wiki/PerformanceEnhancements2
A patch is attached to the proposal.
Effects of this proposal in brief for users of larger catalogs:
- speed up startup time
- speed up index building used by massive ops, harvesters, csw transaction, rebuild index, group delete, category delete, bulk import
- speed up returning search result to user (for large result sets) by introducing configurable limit on number of results used in search summary builder
Other effects:
- postgis can be specified as a gast database option and will then be used for spatial index (by CSW spatial searches) - adapted from work of Jessie Eichar
- system admin can configure the maximum size of 'select all' in Administration>System Configuration
- system admin can configure how often the background lucene optimizer task runs in Administration>System Configuration
- optimize lucene index now operation in Administration menu
Not related to Performance Enhancements but in the patch:
- elementName support introduced for CSW
Jar updates:
geotools 2.6.2
lucene 2.9.2
geoapi 2.3
Thanks to all contributors to this patch - especially Jose Garcia and Francois-Xavier Prunayre!
Cheers,
Simon
+1 for me Simon. Great work !
