Continuous Queries (CQ) allow clients to subscribe to server-side VMware GemFire events using a SQL-like query. When a client registers a CQ, the client will receive all events that modify the query ...
Eviction of entries from a VMware GemFire region allows control over the system resources consumed by any given region. This is a simple example that demonstrates eviction of entries from a region. T...
Expiration of entries from a VMware GemFire region can be used to prevent stale entries from lingering in a region. This is a simple example that demonstrates expiration of entries from a region. Thi...
This example calculates which integers in the region are prime numbers. The determination of the primes occurs inside the server by way of a VMware GemFire function and the client displays the primes...
Durable messaging can be used for subscriptions that you need maintained for your VMware GemFire clients even when your clients are down or disconnected. This example demonstrates VMware GemFire’s Du...
This example demonstrates simple queries on a VMware GemFire region. In this example, two servers host a single partitioned region with entries that represent employee information. The example does q...
This example demonstrates putting values into a VMware GemFire replicated region and retrieving the values using the GemFire REST API. This is a simple example that demonstrates putting values into a...

This example starts a GemFire cluster and uses the JSON-related APIs to convert a JSON string into a JsonDocument. The converted JSON strings are stored as region entry values. The GemFire JSON-relat...
In this example, two VMware GemFire servers host a single partitioned region with entries that represent employee information. The example indexes the first and last names of employees. This example ...
These examples demonstrate how to use GemFire's LuceneSerializer and LuceneQueryProvider APIs to customize how GemFire data is stored and indexed in Lucene. All the examples are run from Example.java...
This example demonstrates an index for OQL queries on a VMware GemFire region. A region can contain objects of arbitrary complexity, including objects that contain other objects. The values of a regi...
This example demonstrates the basic property of partitioning where the data entries are distributed across all VMware GemFire servers that host a region. The distribution is like database sharding, e...
In this example, a VMware GemFire server hosts a partitioned region that stores strings. The example shows entry values being overflowed to disk and removed from memory. This examples demonstrates ho...
This example demonstrates VMware GemFire persistent regions. The data for a region resides in memory in the JVM for the server. When a region is persistent, the data for that region is also preserved...
This example demonstrates publishing metrics from GemFire to a monitoring system comprised of Prometheus and Grafana. Steps to Run and Validate the Example From the gemfire-examples/micrometerMetrics...
This is example demonstrates putting a map of values into a VMware GemFire region, checking the size, and retrieving the values. This example assumes you have installed JDK11 and GemFire. Steps From ...
This is a simple example that illustrates how to colocate the data of two VMware GemFire regions. By default, GemFire selects the data locations for a partitioned region independent of the data locat...
This example demonstrates the use of VMware GemFire transactions to protect consistency during concurrent access and modification of data. This is a simple example that demonstrates the use of transa...
This example demonstrates GemFire support for asynchronous replication between clusters. WAN replication allows remote GemFire clusters to automatically keep their region data consistent through the ...
This example demonstrates GemFire support for asynchronous replication between clusters using Delta objects. This example demonstrates GemFire support for asynchronous WAN replication between cluster...
In this example, a VMware GemFire cache listener is installed and notified of each entry creation and then adds it to a queue of events. This is a simple example that demonstrates the use of a cache ...
This is a simple example that demonstrates loading values using a VMware GemFire CacheLoader. This is a simple example that demonstrates loading values using a CacheLoader. Invoking Region.get() caus...
