MongoDB uses zstd and QATzip

[Microcarft]

I would like to know if, when using MongoDB and switching to the zstd compression algorithm, I can use this plugin to call QAT hardware?

[cfzhux]

Yes, MongoDB can use qat to accelerate the compression

[Microcarft]

是的，MongoDB 可以使用 qat 来加速压缩

Thank you very much for your answer. I'm curious whether I should use QATlib+QATzip or directly use QAT-ZSTD-Plugin after installing the driver.

[cfzhux]

你是想使用QAT加速mongdb中的ZSTD吗？如果是的，不用安装qatzip，需要安装qatlib和qat zstd plugin, 然后参考https://github.com/intel/QAT-ZSTD-Plugin?tab=readme-ov-file#how-to-integrate-qat-sequence-producer-into-applications 这部分添加一些代码

[Microcarft]

Thanks, and I would also like to ask if I need to install both Intel® QAT Driver for Linux* Hardware v2.0 and QATlib? I am using the latest 6.9.7 kernel for testing and I am not sure what will happen next.

it seems that you are using QAT OOT package, you can refer to https://intel.github.io/quickassist/GSG/2.X/installation.html, you don't need to install QATlib(https://github.com/intel/qatlib), it is for QAT In-tree software package

谢谢，我还想问一下我是否需要同时安装英特尔® QAT 驱动程序（适用于 Linux* 硬件 v2.0）和 QATlib？我正在使用最新的 6.9.7 内核进行测试，但不确定接下来会发生什么。

看来你正在使用 QAT OOT 包，你可以参考https://intel.github.io/quickassist/GSG/2.X/installation.html，你不需要安装 QATlib( https://github.com/intel/qatlib )，它是用于 QAT In-tree 软件包

Oh, that's really unfortunate. After installing the qat_4xxx module in the kernel, I tried to install it using the package mentioned in the link.

谢谢，我还想问一下是否需要同时安装英特尔® QAT 驱动程序（适用于 Linux* 硬件 v2.0）和 QATlib？我正在使用最新的 6.9.7 内核进行测试，但不确定接下来会发生什么。

看来你正在使用QAT OOT包，你可以参考https://intel.github.io/quickassist/GSG/2.X/installation.html，你不需要安装QATlib( https://github.com/intel/ qatlib )，它是用于 QAT In-tree 的

Sorry, the problem with ZSTD-Plugin has not been solved yet. I tried to find the three APIs you mentioned in Mongo, but there was no result. It seems that Mongo's WiredTiger does not call these three APIs?

Could you try to use ZSTD_compress2 or ZSTD_compressStream2 to replace the API called by Mongo?

Thanks for your reply! I am trying it as you said. I successfully compiled QAT-ZSTD-Plugin not long ago and got the libqatseqprod.so file. Then I found the source code of zstd1.5.5 in the source code of MongoDB and modified the code according to this instruction:

How to integrate QAT sequence producer into zstd

Then the zstd module was successfully compiled and run.

However, when I performed a simple performance test on the zstd module with QAT-ZSTD-Plugin added, I found that the compression time of multiple test samples was much higher than that of the normal zstd module compiled with the same source code. This is very puzzling, but I still continue to try to compile MongoDB directly to verify whether this set of processes can succeed - even if the performance of the zstd module with QAT is not normal.
