• Reducing Cold Starts on AWS Lambda with Java Runtime - Future Ideas about SnapStart, GraalVM and Co
  1 project | dev.to | 13 Nov 2023

  In the previous 8 parts of our series about AWS Lambda SnapStart we measured the cold starts of Lambda function with Java 11 and 17 runtime first without without and with enabling of SnapStart and also applying various optimization techniques like priming when using SnapStart. You can refer to the cold start times measured with GraalVM Native Image. Current measurements reveal, that the fastest cold start times can be achieved with GraalVM Native Image followed by SnapStart with priming (in case you can apply such optimization for your use case, for example when you’re using DynamoDB as your database of choice), followed by SnapStart without any optimizations. Of course the slowest cold start times you will experience without using GraalVM Native Image and SnapStart. See the summarized measurements in my previous articles of this series or in one of my presentations like this one.

• Measuring Java 11 Lambda cold starts with SnapStart - Part 7 re-measuring
  2 projects | dev.to | 1 Oct 2023

  Now the measurements of cold start times (and overall API Gateway end-to-end latency) make complete sense and I assume that AWS made a fix to display the "Restore Duration" and thefore the entire cold start time correctly. Nethertheless these are still quite big cold start times (especially if you can't prime some invocations to reduce them), comparing to other Lambda runtimes like Node.js and Python. Obviously GraalVM Native Image shipped with Lambda Custom Runtime can provide much better results (see Results from GraalVM Native images running in custom runtime) but with different set of trade-offs. Of course in case of using SnapSart, the snapshot restore times can be improved in the future, so I hope that we can further reduce the cold start times with Java by several hundred additional milliseconds.

• Measuring Java 11 Lambda cold starts with SnapStart - Part 3 Using Quarkus Framework
  4 projects | dev.to | 21 Dec 2022

  If we compare these metrics with AWS Lambda with plain Java (and AWS SDK for Java version 2) and Micronaut Framework with SnapStart enbled we'll notice that using the Micronaut Framework the average cold start with Quarkus is quite comparable with the first and better than the latter. If we compile our application with GraalVM Native Image and deploy our Lambda as Custom Runtime (which is beyond the scope if this article), we can further reduce the cold start to between 450 and 550ms, see the measurements for the comparable application.
