Developing with vFabric GemFire

Developing with vFabric GemFire explains main concepts of application programming with vFabric GemFire. It describes how to plan and implement regions, data serialization, event handling, delta propagation, transactions, and more.

• Region Data Storage and Distribution
  The vFabric GemFire data storage and distribution models put your data in the right place at the right time. You should understand all the options for data storage in GemFire before you start configuring your data regions.
• Partitioned Regions
  In addition to basic region management, partitioned regions include options for high availability, data location control, and data balancing across the distributed system.
• Distributed and Replicated Regions
  In addition to basic region management, distributed and replicated regions include options for things like push and pull distribution models, global locking, and region entry versions to ensure consistency across GemFire members.
• Consistency for Region Updates
  GemFire ensures that all copies of a region eventually reach a consistent state on all members and clients that host the region, including GemFire members that distribute region events across a WAN.
• General Region Data Management
  For all regions, you have options to control memory use, back up your data to disk, and keep stale data out of your cache.
• Data Serialization
  Data that you manage in vFabric GemFire must be serialized and deserialized for storage and transmittal between processes. You can choose among several options for data serialization.
• Events and Event Handling
  vFabric GemFire provides versatile and reliable event distribution and handling for your cached data and system member events.
• Delta Propagation
  Delta propagation allows you to reduce the amount of data you send over the network by including only changes to objects rather than the entire object.
• Querying
  vFabric GemFire provides a SQL-like querying language that allows you to access data stored in GemFire regions.
• Continuous Querying
  Continuous querying continuously returns events that match the queries you set up.
• Transactions
  The vFabric GemFire API for distributed transactions has the familiar relational database methods, begin, commit, and rollback.
• Function Execution
  You can write, register, and execute functions for particular use cases.
