2010-06-30 RELEASE 1.1 NEW: * Cache statistics are available as MBean using JConsole. * Deactivated the caching of raster elements to improve performance. DDED: * A central Configuration instance that might be used to adjust settings of the geo-backend. 2010-04-28 RELEASE 1.0 NEW: * Support for MultiLinestring and MultiPolygon detection retrieved by the database. * Spatial queries using LineStrings can be sent to the database. * Sql-cache synchronization after database upates have taken place. A thread is started in a specific time interval. Elements are removed from cache if the sql-statement that has been used to retrieve these elements contains a table that have been updated since the last synchronization. The time interval (in seconds) can be configured via system property 'caching.cleaner.interval' (e.g. caching.cleaner.interval=600 for an interval of 10 minutes). Added: * JavaDoc documentation. 2010-03-08 RELEASE 0.5 2010-01-27 RELEASE 0.4 New: * Experimental Cache for database queries and results of parameterisation: Database queries are transparent against cache. * Support for raster data access to SDE via RasterObject * Added interpolation for bilinear and bicubic spline interpolation on rasters * Improved connection pooling for re-use of connections (#34) * Improved memory consumption of SQL results produced by SDE by over 90% while removing redundancies for objects (especially date objects): e.g. from 256 MB per Interpolation to 15 MB. (#107) 2009-12-17 RELEASE 0.3 New: * !!!! Java6 is mandatory now! Older version are not supported any longer !!! * Added "point on polygon" spatial query support. Fixed: * Avoid index out of bounds exception in some case when accessing database columns that are not provided by the database result set. 2009-11-13 RELEASE 0.2 New: * Added spatial query support for the first use cases. It uses OGC Simple Features for SQL Syntax (SFS) to the inside and OGC WKT (Well Known Text) for geometry respresentations * Enhanced configuration to ArcSDE Backend in Pool-Mechanism for fine-tuning interaction and pooling. * Added support for INNERJOIN, ORDER BY and GROUP BY for spatial queries (needs more testing) * Support for gaps in temporal and spatial data added. Improvements: * Improved memory handling of Backend-results in geo-backend * Stabilized binding to ArcSDE Backend (issue 34), https://roundup-intern.intevation.de/gnv/issue34 2009-10-07 RELEASE 0.1 New: * Imported proto type database access layer. * Made access layer look like java.sql.*
