When should I use db2lake instead of Kreuzberg?

Automated data extraction from relational databases to data lake formats (Parquet, Delta Lake). Teams building lakehouse architectures from legacy database sources with minimal custom code. Low-code database-to-lake ingestion without writing custom Spark or SQL extraction jobs

When should I use Kreuzberg instead of db2lake?

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 db2lake?

Small project with limited community documentation and few production references. Connector support is narrower than Airbyte or dlt for diverse or exotic source systems. Limited transformation capabilities — focused on ingestion only with no transform layer

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

Key Features

db2lake

1Tool for migrating relational database data to data lake formats (Parquet, Delta)
2Reads from PostgreSQL, MySQL, Oracle, and SQL Server
3Writes Parquet files with correct schema mapping and partitioning
4Supports full and incremental extraction modes
5Configurable via YAML for repeatable, version-controlled migrations

Kreuzberg

1Python library for extracting text from PDFs, images, Office documents, and HTML
2Async-first API for non-blocking document processing in Python services
3Uses Tesseract OCR for image-based text extraction
4Returns structured text with metadata about the source document
5Minimal configuration — sensible defaults for common document types

How Python Data Engineers Use These Tools

db2lake

Python data engineers use db2lake to bootstrap data lake migration projects — extracting historical data from relational databases and writing it as partitioned Parquet files to S3 or HDFS. Once the initial migration is done, incremental extractions keep the lake in sync, and Python-based PySpark or DuckDB pipelines take over for ongoing processing.

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.
