Data Lake Implementation · Swansea
Data Lake Implementation in Swansea
Data lakes for Swansea organisations holding volumes or formats a warehouse handles badly — logs, sensor readings, documents, images. The failure mode is well known enough to have a name: without catalogue, schema and ownership, a data lake becomes a data swamp within about a year.
Why this comes up
The problem
Data is accumulating in cloud storage because keeping it is cheap. Nobody knows what is there, what format it is in, or whether any of it can still be read.
What you get
What we deliver
- Zoned storage — raw, cleaned and curated, so quality is knowable from location
- A table format such as Delta or Iceberg, giving schema and transactions over files
- A catalogue, since undiscoverable data has no value regardless of volume
- Retention and lifecycle rules, because storing everything forever is a choice
- Access control and personal data classification, which cheap storage encourages neglecting
- A query path, so analysts reach the data without engineering help

Data Lake Implementation in Swansea — common questions
- Lake or warehouse?
- A warehouse for structured business data answering known questions — most reporting. A lake for volume, semi-structured formats and data whose use is not yet decided. Many organisations need both, and conflating them produces something that serves neither well.
- How do lakes become swamps?
- By accumulating data with no catalogue, no schema enforcement and no owner. Storage is cheap enough that nobody says no, and two years later the contents are undocumented files in formats whose meaning left with the person who wrote them.
- Why use a table format over plain files?
- Delta and Iceberg add schema enforcement, transactions and time travel over object storage. Without them you have files that different tools interpret differently, and a partial write leaves data in a state nothing can read reliably.
- Should we keep everything?
- No, and treating cheap storage as a reason to is how the problem starts. Retention needs deciding per dataset, particularly for anything containing personal data, where indefinite retention is a compliance exposure rather than an asset.
- Do you work with businesses across Swansea?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Swansea and the surrounding Swansea area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Swansea businesses do you usually work with?
- Bilingual public-facing systems for institutional clients, and seasonal booking for the Gower tourism trade. Beyond that we work across Higher Education, Healthcare, Manufacturing, Tourism and Public Sector.
- Do you cover the areas around Swansea?
- Yes — we work throughout Wales, including Cardiff, Newport. Swansea is an urban area of roughly 240,000+, and we take on work across the wider Swansea region rather than the city boundary alone.
