Lambda cold start possible solution?

Question

Is scheduling a lambda function to get called every 20 mins with CloudWatch the best way to get rid of lambda cold start times? (not completely get rid of)...

Will

Answer 1

Among adding more memory for lambda, there is also one more approach to reduce the cold starts: use Graal native-image tool. The jar is translated into byte code. Basically, we would do part of the work, which is done on aws. When you build your code, on loading to AWS - select "Custom runtime", not java8.

Beware:

but it also has its limitations; it does not support dynamic class loading, and reflection support is also limited
