GeoMesa 1.2.5 Release Notes

Aug 15, 2016

GeoMesa 1.2.5 includes 45+ improvements and bug fixes.

Highlights

Improved Polygon and LineString Indexing

GeoMesa now includes XZ2 and XZ3 indexes for geometries with extents (e.g. non-points)
XZ indexes avoid object duplication and provide multi-level resolution indexing
XZ indexes are now the default for non-point geometries (e.g. LineStrings and Polygons)

Configurable Date Intervals for Z3 and XZ3 Indexes

Z3 and XZ3 indexes can partition data by:
- day/millis
- week/seconds
- month/seconds
- year/minutes
Default indexing is week/seconds
Modifying the date intervals help with queries that are much larger or much smaller than a week

Full Multi-Level Attribute Visibility Support

Updates partial support from 1.2.4
Attributes within a simple feature can have different visibility levels

Jupyter Notebook Documentation
