[geomesa-users] GeoMesa 1.2.3 Released
|
Hi everyone,
The next bugfix release of GeoMesa (1.2.3) is now available! Thanks to
everyone who contributed bug fixes, new features, and ideas for
improving GeoMesa.
New versions of downstream projects including geomesa-ext, geomesa-nifi,
and others will be updated in the next few days.
- Andrew
----------------------------------
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
Upgrading
* GeoMesa 1.2.3 supports upgrade in place from versions 1.1.0.rc.7
through 1.2.2
* Shutdown the geoserver and upgrade the distributed runtime in accumulo
as well as the geomesa jars in the webserver
