Qatzip Compressor

• :ref:v3 API reference <envoy_v3_api_msg_extensions.compression.qatzip.compressor.v3alpha.Qatzip>

Qatzip compressor provides Envoy with faster hardware-accelerated gzip compression by integrating with Intel® QuickAssist Technology (Intel® QAT) <https://www.intel.com/content/www/us/en/architecture-and-technology/intel-quick-assist-technology-overview.html>_ through the qatlib and QATzip libraries.

Example configuration

An example for Qatzip compressor configuration is:

.. literalinclude:: _include/qatzip.yaml :language: yaml

How it works

If enabled, the Qatzip compressor will:

• attach Qat hardware
• create Threadlocal Qat session context for each worker thread

When a new http request comes, one worker thread will process it using its Qat session context and send the data needed to be compressed to Qat hardware.

Installing and using QATzip

For information on how to build/install and use QATzip see QATzip <https://github.com/intel/QATzip>_.
