Checkout the NodeJS version of BigIO.

Python and Go versions of BigIO coming soon.

Note: The API has changed with version 1.2 and is not backwards compatible. io.bigio.Speaker has been renamed to io.bigio.BigIO and the boostrap method has been moved into this class. All instances of Speaker speaker = Starter.boostrap(); need to be replaced with BigIO bigio = BigIO.bootstrap();


BigIO is a fast, distributed messaging framework written entirely in Java. The framework can run in a single process or across multiple instances running across a network. Message communication in-VM is extremely fast with upwards of 4.6 million messages per second. Communication across multiple instances on a network happens via TCP or UDP connections. Even across the network, the framework can process around 300,000 messages per second (150,000 messages sent and 150,000 messages received).

One of the newest features is the ability to send and receive fully encrypted messages and/or run over TLS/SSL. The ability to do secure messaging sets BigIO apart from other middleware such as DDS.

To get started using BigIO, download the BigIO runtime, and deploy your jar to the 'components' directory. The API can be used by adding the following to your Maven pom.
