When should I use AWS Kinesis instead of Kreuzberg?

Managed real-time data streaming on AWS with per-shard scalability and no Kafka to operate. Teams in the AWS ecosystem needing event streaming integrated with Lambda, Firehose, and Redshift. Serverless stream processing where Kinesis Data Analytics handles SQL or Flink queries

When should I use Kreuzberg instead of AWS Kinesis?

Extracting clean text from PDFs, Office documents, and images for data ingestion pipelines. Document AI pipelines where reliable text extraction is the critical first preprocessing step. Ingesting unstructured document formats into downstream NLP or search indexing workflows

What are the main weaknesses of AWS Kinesis?

Per-shard billing becomes expensive for high-volume or very bursty workloads. Retention is capped at 365 days maximum — Kafka is better for indefinite event log retention. Vendor lock-in: Kinesis API is AWS-specific with no portable alternative

What are the main weaknesses of Kreuzberg?

Text extraction quality varies by document complexity, layout, and scan quality. Heavy system dependencies (Tesseract OCR, LibreOffice) required for full feature coverage. No structured data extraction — text output requires additional NLP parsing downstream

How Python Data Engineers Use These Tools

AWS Kinesis

Python data engineers use `boto3`'s Kinesis client to put records onto a Data Stream from Lambda functions or EC2-based producers. Consumer applications use the Kinesis Client Library (KCL) with Python bindings, or the `amazon-kinesis-client` Python wrapper, to process shards in parallel with automatic checkpointing — a common pattern for real-time log processing and event enrichment.

Kreuzberg

Python data engineers use Kreuzberg to build document ingestion pipelines that extract text from uploaded PDFs, scanned images, and Office files. The async API integrates cleanly into FastAPI-based document processing services — an endpoint accepts a file upload, Kreuzberg extracts the text asynchronously, and the pipeline stores the result in a search index or warehouse for downstream analysis.
