The contribution redirects all image conversion to AWS Lambda. Currently, Nuxeo Lambda used for picture conversion creation. Current implementation uses streaming to download the initial file from Nuxeo. This approach allows to get around with storage limitation at AWS Lambda in many cases.
The contribution exposes Picture.Recompute automation operation. The operation accepts only one parameter - query.
It will recompute all Pictures that satisfies the given query using AWS Lambda. To get more information about calling automation operations
in Nuxeo, please follow our official documentation.
AWS Lambda dramatically speeds up computation time.
Benchmarks show the ability to recompute a thousand of various PSD files (18 - 600MB)in less than 2 minutes.
In the benchmark test, each entry creates 4 picture views of different size.
Currently AWS Lambda limited with:
The contribution contains two parts. In nuxeo-lambda-image-conversion you can find server side contribution. This should be build with regular maven command from the root directory.
mvn clean install
to set up the function name used at your AWS account you need to update nuxeo.conf property nuxeo.lambda.image.conversion. Otherwise nuxeo-lambda-picture name will be used.
aws_lambda_impl contains code ready to use on AWS Lambda. By default AWS has Imagemagick version 6.x. We highly recommend to update it to the 7th version.
To do so, you need to build Imagemagick from source under the same environment used on AWS. You can use the following script:
sr/bin/env bash
yum -y install libpng-devel libjpeg-devel libtiff-devel gcc
-O http://www.imagemagick.org/download/ImageMagick.tar.gz
zxvf ImageMagick.tar.gz
mageMagick
nfigure --prefix=/var/task/imagemagick --enable-shared=no --enable-static=yes
make install
zcvf ~/imagemagick.tgz /var/task/imagemagick/
At the end you will have imagemagick.tgz file. Move it to aws_lambda_impl
To prepare Lambda for upload, use following commands:
ws_lambda_impl
i
-r lambda.zip *
Now, lambda.zip is ready to be uploaded to your AWS Lambda.
If you have not yet created your AWS Lambda, please follow the official
documentation.
Make sure that you configured your function accordingly with your requirements. We suggest to set timeout at least to 2 minutes. Average RAM consumptions is about 700 MB for PSDs under 300MB.
