v0.52.0

Important news and breaking changes

This releases introduces the feature flag aws-sdk-v2 (by @kgeckhart), which changes YACE networking layer to use the AWS sdk v2 package. Read on for more details and considerations.

• The main benefit of sdk v2 is deserialization/serialization is done via code generation vs reflection which drastically lowers memory/cpu usage for large scrape jobs
• Considerations before enabling sdk v2:
  1. FIPS is not supported in v2 as v2 delegates all URL resolution to the sdk and AWS does not have FIPS compliant endpoints for AutoScaling API and Tagging API. The v1 implementation worked around this by hard coding FIPS URLs where they existed and using non-FIPS URLs otherwise. This work around was not ported to v2 and is unlikely to be ported.
  2. sdk v2 uses regional sts endpoints by default vs global sts which is considered legacy by aws. The sts-region job configuration is still respected when setting the region for sts and will be used if provided. If you still require global sts instead of regional set the sts-region to aws-global.
