Simple repo to test the performance of the kinesis library.
- Run the command line version via
gradle run - Inspect timing. Takes about 2.3 seconds on my laptop
- build and test locally via
sam build && sam local invoke - Inspect timing. Takes about 2.4 seconds on my laptop
- Deploy:
sam deploy - Invoke via "Test" panel on Lambda console or CLI, as preferred.
- Observe time and log:
