Episode notes
EMR Security And S3A Performance Boost
- Amazon EMR now uses Lake Formation fine-grained access control and S3A as the default connector to improve security and performance for big data workloads.
- These changes simplify access management and optimize S3 performance for Hadoop, Spark, and Hive on EMR.
Test New Instance Types Before Swapping
- When a new EC2 instance type like i8g is supported, run tests and validate configurations before swapping instances.
- Benchmark your workload as performance and latency characteristics can differ substantially from previous generations.
Predict Model Costs With Token Counts
- Bedrock's Count Tokens API reveals token counts before inference to improve cost projection and transparency.
- Initial support covers Claude models and will expand to more models and regions over time.
