Running with shared network mode ( ThreadingMode.SHARED_NETWORK) reduces the thread count to two: To further improve performance, pin the threads to specific CPU cores. This is the default mode, and best used when performance is a concern and the system has sufficient resources. the Driver Conductor ( driver-conductor in thread dumps, uses conductorIdleStrategy).the Receiver ( receiver in thread dumps, uses receiverIdleStrategy).the Sender ( sender in thread dumps, uses senderIdleStrategy).In the dedicated threading mode ( ThreadingMode.DEDICATED), the Media Driver will use 3 threads, each with a specific idle strategy: It can be highly detrimental to application stability and performance to over allocate resources to the Aeron process beyond those available. Selecting the right resource allocation in the Media Driver should consider both the resources available to the process and the performance requirements. Sets up a Media Driver with the ability to introduce loss Sets up the Media Driver with optimum settings for low latencyįound in the test folder.
Other than the Media Driver, there are two other variants found in the Aeron source code: Typeįound in the samples folder. When running out of process, you can use either the Java or C Media Driver. The Media Driver can either be run embedded or out of process. This folder holds all open publication log buffers.Ĭonfiguration & Runtime Deployment options ¶ Useful for understanding the network behavior over time. This file stores all details of packet loss by Aeron. This folder holds any open images of remote publications It is also the home of the Aeron counters as read by AeronStat. This is the command-and-control memory mapped file shared between the Aeron Client and Media Driver. The Media Driver folder contains: PathĪn empty Log Buffer file, ready to be copied for a new publication The above shows a Media Driver folder with a single IPC Publication open. For more details, see Publications & Subscriptions.
You will need to ensure that the file system has sufficient storage space for all of the images and publications.
