Developing with VMware Tanzu GemFire

This topic provides links to documentation that explains main concepts of application programming with VMware Tanzu GemFire. These topics describe how to plan and implement regions, data serialization, event handling, delta propagation, transactions, and more.

For information about Tanzu GemFire REST application development, see Developing REST Applications for VMware Tanzu GemFire.

• Region Data Storage and Distribution

  The Tanzu 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 Tanzu 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 cluster.

• 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 Tanzu GemFire members.

• Consistency for Region Updates

  Tanzu GemFire ensures that all copies of a region eventually reach a consistent state on all members and clients that host the region, including Tanzu GemFire members that distribute region events.

• 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 Tanzu 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

  Tanzu 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

  Tanzu GemFire provides a SQL-like querying language, Object Query Language (OQL), that allows you to access data stored in Tanzu GemFire regions.

• Continuous Querying

  Continuous querying continuously returns events that match the queries you set up.

• Transactions

  Tanzu GemFire provides a transactions API, with begin, commit, and rollback methods. These methods are much the same as the familiar relational database transactions methods.

• Function Execution

  A function is a body of code that resides on a server and that an application can invoke from a client or from another server without the need to send the function code itself. The caller can direct a data-dependent function to operate on a particular dataset, or can direct a data-independent function to operate on a particular server, member, or member group.
