Data engineering for AI

AI Data Pipeline Development

An AI data pipeline pulls data from your source systems, cleans and validates it, and delivers it reliably to machine learning models, RAG systems and analytics. Context Studios, an AI-native development studio in Berlin, builds such pipelines to fit your data landscape, from concept to production operation.

What is AI data pipeline development?

AI technology

AI data pipeline development covers extracting, transforming and delivering data for machine learning models, RAG systems and analytics. Unlike classic ETL, it adds feature engineering, embedding generation, automated quality checks and consistency between training and inference.

ETL/ELT, feature stores, embedding pipelines, data quality
Technologies
Apache Spark, dbt, Airflow, Kafka, Prefect
Target group
Companies with complex data landscapes and AI plans
Project duration
Typically 4–14 weeks depending on data volume and sources
Compliance
GDPR-compliant data storage, data lineage, auditability

Which data pipeline services do we offer?

From raw data extraction to an AI-ready feature store

(01)

ETL/ELT pipelines

Scalable extraction, transformation and loading pipelines with dbt, Spark or Polars, from batch processing for data warehouses to streaming pipelines with Apache Kafka for real-time features.

(02)

Embedding pipelines & vectorisation

Specialised pipelines for RAG systems: document extraction, chunking, embedding generation and incremental updates of vector databases, tuned to document types and embedding models.

(03)

Feature store & feature engineering

Central feature stores that provide consistent features for training and inference, plus automated feature engineering with domain-specific transformations and time-series aggregations.

(04)

Data quality & validation

Automated checks with Great Expectations or dbt tests, schema validation and anomaly detection, so your AI models work on clean, consistent data.

(05)

Data observability & lineage

Traceability of every record from source to model, with lineage graphs, impact analyses and alerts on unexpected data changes.

(06)

Incremental & real-time pipelines

Change data capture and streaming architectures that only process changed data, for cost-efficient updates even with very large datasets.

Frequently asked questions about AI data pipelines

(01)How does an AI data pipeline differ from a normal ETL pipeline?
AI data pipelines have additional requirements: feature engineering for ML models, embedding generation for vector databases, incremental processing for real-time features, data drift detection and their own quality metrics. They also have to ensure that training and inference use identically prepared data; otherwise models degrade unnoticed.
(02)Do we need real-time or batch processing?
That depends on the use case: recommendation systems and fraud detection need real-time streaming, while reporting, model training and historical analyses work well in batch. Many systems combine both in a lambda or kappa architecture. We choose the simplest solution that meets your latency requirement, because streaming means more operational effort.
(03)How large can the data volumes be?
Our pipelines scale from a few gigabytes into the terabyte range. Apache Spark distributes large batch jobs across many machines, and streaming platforms such as Kafka handle high event rates. We optimise costs through partitioning, incremental processing and suitable storage classes so they do not grow faster than the benefit.
(04)How do you ensure data quality?
With automated quality gates at every pipeline step: schema validation, constraint checks, statistical anomaly detection, duplicate detection and referential integrity checks. Great Expectations or dbt tests document the expectations for the data and automatically hold back faulty records before they distort models or reports.
(05)How much does it cost to run a data pipeline?
The running costs of a cloud pipeline depend mainly on data volume, update frequency and the services chosen. We quantify them concretely during scoping and reduce them with incremental processing, spot instances and low-cost storage classes. For the development itself: fixed price after scoping, proposal within 48 hours.
(06)Can existing data warehouses be integrated?
Yes. We integrate common data warehouses such as Snowflake, BigQuery, Redshift and Databricks as well as on-premise databases. Existing dbt models can be extended, Airflow DAGs added to and existing data models used as the basis for AI features. That way we build on your previous investments instead of starting from scratch.
(07)How is the GDPR complied with in data pipelines?
Through privacy by design: detection of personal data and automatic masking or pseudonymisation in the pipeline, column-level access controls, deletion workflows for data subject requests and audit logging of all data access. Data lineage documents the complete data flow and makes it easier to answer questions from data protection officers and authorities.
(08)What is a feature store and do we need one?
A feature store is a central repository for ML features. It keeps training and inference consistent, allows features to be reused and provides point-in-time correct values for historical training data. It makes sense when several models use the same features or real-time features are needed; for a single model a simpler solution is often enough.
(09)How long does it take to build a data pipeline?
A single ETL pipeline with one source and one target is typically implemented in 2–4 weeks. A complete data platform with several sources, a feature store, a streaming component and monitoring usually takes 8–14 weeks. We recommend an iterative build: the most business-critical pipeline first, then extend step by step.
(10)Can we process unstructured data such as PDFs and emails?
Yes. Our pipelines combine OCR, LLM-based extraction and document parsers for PDFs, emails, Word files and other formats. The extracted content is structured, converted into embeddings and, depending on the purpose, stored in the data warehouse, a vector database or both, including a reference to the original document.
