Important Notes

GeoMesa Accumulo Runtime Jar Required for Ingest

  • The GeoMesa distributed runtime jar now must be installed on the cluser and configured for VFS classloading prior to ingest
  • Supports pre-computed bounds and statistics

Highlights

Pre-computed statistics & Query Planning

  • GeoMesa now stores statistics about the spatiotemporal bounds and distribution of data at ingest time.
  • Statistics can be used for more accurate index selection during query planning.
  • Pre-computed statistics are available via a REST API that can be configured using the GeoMesa-Ext CatalogListener. 

Keywords Stored in GeoMesa

  • Keywords can be added to the datastores metadata either at SFT creation in Scala or typesafe config or added via command-line tools. 
  • Useful for configuring stealth keywords

Multi-Level Attribute Visibility

  • Draft/first-pass per-attribute visibility controls.
  • Attributes within a simple feature can have different visibility levels

Data SFT/Converters In Tools

  • Common SFT/Converter TypeSafe config definitions now ship with tools (e.g. twitter, geolife, geonames, etc.)
  • Scripts for downloading data are included in tools

Native API View 

  • Domain objects in the Native API can now leverage GeoMesa secondary indexing

Other Notable Changes

  • Kafka Datastore Fixes - Fixed isssue for CQL queries with multiple spatial filters
  • Spark/Scala 2.10 Support - Updates to GeoMesaSpark and continuing work to support Spark/Scala 2.10
  • Updated Documentation - All supported data stores have their own chapters in the User Manual, with installation and GeoServer configuration information. Additional libraries are described in a modules and libraries chapter in the User Manual.
  • Elastic MapReduce (EMR) Scripts -  EMR scripts are now included in the tools
