GeoMesa 1.2.5 Release Notes

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
