Is GemFire distributed cache?
High-performance application cache, a database, and much more. VMware Tanzu GemFire is a distributed, in-memory, key-value store that performs read and write operations at blazingly fast speeds.
What is GemFire cache?
Caches are an abstraction that describe a node in a GemFire distributed system. Application architects can arrange these nodes in peer-to-peer or client/server topologies. Within each cache, you define data regions. A replicated region stores identical copies of the data on each cache member of a distributed system.
What is GemFire and Geode?
GemFire is a distributed data management platform that provides a key-value data grid along with advanced distributed system features, such as event processing, continuous querying, and remote function execution. This guide assumes some familiarity with the commercial Pivotal GemFire or Open Source Apache Geode.
Is GemFire a database?
GemFire is a combined data and compute grid with distributed database capabilities, highly available parallel message queues, continuous availability, and an event-driven architecture that is linearly scalable with a super-efficient data serialization protocol.
What is the use of GemFire cache?
Cache. The cache in the GemFire provides the essential data management services as well as manages the connectivity to other peers.
Is GemFire open source?
Pivotal Gemfire is not free, but if you are not using Gemfire as part of an enterprise, then Apache Geode is the same technology. Currently the newest version of Pivotal Gemfire is based on the open source core of Apache Geode(which as of today is a top level Apache project).
What is GemFire locator?
The locator is a Tanzu GemFire process that tells new, connecting members where running members are located and provides load balancing for server use. You can run locators as peer locators, server locators, or both: Server locators give clients connection information to servers running in the locator’s cluster.
What is a GemFire server?
A GemFire server is a Pivotal GemFire process that runs as a long-lived, configurable member of a cluster (also called a distributed system). The GemFire server is used primarily for hosting long-lived data regions and for running standard GemFire processes such as the server in a client/server configuration.
What is the role of the cache in Gemfire?
The cache in the GemFire provides the essential data management services as well as manages the connectivity to other peers. The cache configuration ( cache.xml) describes how the data will be distributed among different nodes: 3.2. Regions Data regions are a logical grouping within a cache for a single data set.
What kind of data is in Gemfire cluster?
GemFire is a high performance distributed data management infrastructure that sits between application cluster and back-end data sources. With GemFire, data can be managed in-memory, which makes the access faster. Spring Data provides an easy configuration and access to GemFire from Spring application.
How is a cache created in tanzu Gemfire?
Tanzu GemFire has one cache type for managing server and peer caches and one for managing client caches. The cache server process automatically creates its server cache at startup. In your application process, the cache creation returns an instance of the server/peer or client cache.
