• tenzir

  15 612 10.0 C++

  Open source security data pipelines.

  

Project mention: Vector: A high-performance observability data pipeline | news.ycombinator.com | 2024-03-17

We're building something similar at Tenzir, but more for operational security workloads. https://docs.tenzir.com

Differences to Vector:

- An agent has optional indexed storage, so you can store your data there and pick it up later. The storage is based on Apache Feather, Parquet's little brother.

- Pipelines operators both work with data frames (Arrow record batches) or chunks of bytes.

- Structured pipelines are multi-schema, i.e., a single pipeline can process streams of record batches with different schemas.
