Is GemFire open source?
1 Answer. 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 are regions in GemFire?
Within a GemFire cluster, you can define distributed regions and non-distributed regions, and you can define regions whose data is spread across the cluster, and regions whose data is entirely contained in a single member. Your choice of region type is governed in part by the type of application you are running.
How does GemFire store data?
Peer-to-Peer Region Storage and Distribution In a properly configured GemFire installation, you store your data in your local members and GemFire automatically distributes it to the other members that need it according to your cache configuration settings. Once configured, GemFire manages the data automatically.
How does GemFire cache work?
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.

What was the impact of the introduction of Gemfire?
The introduction of GemFire into the company’s web and e-ticketing system made it possible to handle holiday traffic of 15,000 tickets sold per minute, 1.4 billion page views per day, and 40,000 visits per second. This kind of sudden increase in volume for a few days a year is one of the most difficult kinds of spikes to manage.
What makes GemFire an in memory data grid?
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. Today, we call this combination of features an in-memory data grid (IMDG).
Is it possible to use Gemfire as a distributed database?
The answer is “yes” to both of those questions, but it is much more than that. 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.
