Data Lake Development Services by GroupBWT
A data lake is a central repository that stores raw and historical data (structured and unstructured) for audit, analytics, and AI.
As a data lake development services company, we deliver the full lifecycle: discovery, architecture, build, hardening, and handover.
Data Ingestion Frameworks
We implement ingestion that survives real-world failures: schema drift, API limits, partial loads, late-arriving data, and failed runs. This prevents “missing days” in reports when upstream systems misbehave.
- Batch ingestion (API/export) with replay support
- Streaming ingestion for telemetry and events
- CDC ingestion for operational databases when the application database must stay the source of truth. This keeps analytics current without putting extra load on production.
Data Lake Architecture Design
We design for durability, predictable cost, and a clear separation between “captured” and “trusted” data. This keeps BI and ML teams from building on raw, unreliable files.
- Storage + catalog + access control baseline (cloud-native)
- Lakehouse-friendly table formats when BI or ML teams need shared governance
- Clear data zones and lifecycle policies
We provide custom data lake implementation solutions on AWS, Azure, or Google Cloud while keeping the same architectural patterns.
Real-Time Data Processing
When you truly need real-time, we design for backpressure, replay, and “catch-up” instead of fragile point-to-point jobs. This helps you avoid gaps and wrong numbers during traffic spikes.
- Stream backbone + consumers (operational + analytics)
- Event-time handling and deduplication strategies
Data Lake Governance and Security
Governance is a product decision, not a checkbox. In plain terms: you decide who can see what, and you can prove it in an audit.
- IAM/RBAC, encryption at rest/in transit, key management
- Dataset ownership, naming standards, retention policies
- Audit logs and access reviews for sensitive domains
BI and Analytics Integration
A lake only creates value when it feeds decisions. We publish curated BI datasets and consistent KPI definitions so teams stop arguing over metrics.
- Curated BI datasets (your “gold” outputs) with stable definitions
- Semantic layer / KPI definitions to stop metric drift
- Integration with tools like Power BI, Tableau, Looker, and modern SQL engines
The myth we challenge is simple: storing everything is not a strategy. At GroupBWT, we start from the 3–5 business questions you must answer, then design the minimum architecture that can answer them today and scale tomorrow. This keeps the scope tight and shows value early.

FAQ
What is the difference between a data lake and a data warehouse?
A data lake keeps raw/historical data flexibly; a warehouse keeps curated, structured data optimised for reporting.
Will my application read directly from the lake?
Usually no. Apps need low-latency operational stores; the lake is for durable history, replay, audit, and analytics.
How do you prevent a “data swamp”?
Ownership + purpose + lifecycle: we only promote data when there’s a consumer and a quality bar.
Do you support AWS, Azure, and Google Cloud?
Yes—core patterns stay the same; managed services change.
When is a data lake the wrong choice?
If you only need a small set of stable BI metrics from clean sources, a warehouse-first approach can be simpler.
How do you handle schema changes?
We design for evolution: additive changes, versioned datasets for breaking changes, and curated contracts for BI.
You have an idea?
We handle all the rest.
