Now GA AWS Lambda SnapStart For Python and .NET Functions
AWS released Lambda SnapStart for Java functions on November 28, 2022, which can increase startup speed by up to ten times
Managing uniqueness: If the content generated by your initialization code is unique and included in the snapshot
AWS advises you to initialize resources that cause startup latency and preload dependencies in your initialization code rather than in the function handler
You can use AWS X-Ray active tracing, Amazon CloudWatch log stream, the Telemetry API to get real-time telemetry data for extensions
When Lambda resumes your function from a snapshot, the connections that your function made during the initialization phase may not be in the same state
Use the get-function-configuration command and enter the version number to verify that SnapStart is enabled for the function version
To update the function configuration, use the AWS CLI command update-function-configuration with the –snap-start option
