The AWS CodeGuru Profiler for AWS Lambda Python
I didn’t see a source licence, so here is the incantation to look at it yourself:
curl $(aws lambda get-layer-version-by-arn --arn \ arn:aws:lambda:us-east-1:157417159150:layer:AWSCodeGuruProfilerPythonAgentLambdaLayer:1 \ --query Content.Location --output text) -o python_profiler.zip
It’s worth a read for anyone that does performance critical Python programming. I learned a new trick to automatically garbage collect temporary objects:
Only glaring performance issue I saw was that they aren’t using dictionary compression. If you are goign to analyize your own tracers I would download zstd, and train it:
zstd --train FullPathToTrainingSet/* -o dictionaryName
I would expect at least an additional 25% savings in compression.
Can’t wait to see the Optimyze solution when they roll out their tools for comparison.
