# flink vs automq

flink and automq share 7 technologies: aws-crt-client, hadoop-common, Hive, s3, org.apache.avro:avro, org.slf4j:slf4j-api, and OpenTelemetry. Both are written in Java.

- [apache/flink](https://seerepo.com/r/apache/flink): Apache Flink
- [AutoMQ/automq](https://seerepo.com/r/AutoMQ/automq): Diskless Kafka® on S3. 10x Cost-Effective. No Cross-AZ Traffic Cost. Autoscale in seconds. Single-digit ms latency. Multi-AZ Availability.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
