## What it is
GeoMesa is an open-source suite of JVM-based tools for large-scale geospatial querying and analytics on distributed computing systems. It provides spatio-temporal indexing over Accumulo, HBase, Cassandra, Redis, and FileSystem data stores, near-real-time stream processing via Kafka, and distributed analytics with Apache Spark, integrating with GeoServer over OGC protocols like WFS and WMS.

## Use cases
- store and query billions of GPS points with spatio-temporal indexes in HBase
- run distributed spatial joins and aggregations with Apache Spark
- stream and process real-time geospatial events through Kafka
- serve massive geospatial datasets to mapping clients via WFS/WMS through GeoServer
- ingest and convert CSV, JSON, Avro, Parquet, and shapefile geodata at scale
- query spatio-temporal data in Cassandra or Redis with Z-curve indexing

## When to choose
- you need petabyte-scale geospatial storage and fast spatio-temporal queries on Hadoop-era infrastructure like Accumulo or HBase
- you want OGC-standard access (WFS/WMS) to big geospatial data through GeoServer
- you need near-real-time spatial stream processing on Kafka
- your team works on the JVM and wants GeoTools-compatible data stores

## When to avoid
- you have small datasets that fit in PostGIS or a single-node spatial database
- you want a lightweight pure-Python or pure-JavaScript geospatial library
- you have no operational capacity to run distributed key-value stores like HBase or Accumulo
- you need a hosted managed service rather than self-operated infrastructure
