ClickHouse Implementation in Swansea

Implementing ClickHouse for Swansea organisations, where the sorting key does the work a set of indexes would do elsewhere. Data is physically ordered by it, so queries that filter along that ordering are extraordinarily fast and queries that do not read far more than they should — which makes the key choice the design decision that matters most.

Why this comes up

The problem

The table is sorted by insertion time, every query filters by customer, and each one reads the entire table.

What you get

What we deliver

  • Sorting key chosen from the filters your queries actually apply
  • Partitioning used at a sensible granularity, since too many partitions hurt
  • Table engine selected for the behaviour you need rather than the default
  • Materialised views used where the same aggregation is repeatedly computed
  • Insert batching designed, as frequent small inserts create merge pressure
  • Compression and codecs considered for the columns where they pay

ClickHouse Implementation in Swansea — common questions

How is the sorting key chosen?
From the columns your queries filter on, ordered by selectivity. It determines the physical layout, so a query aligned with it reads a small fraction of the data while one that is not effectively scans — and unlike a conventional index, you get one arrangement.
Can we just add indexes instead?
Not in the way other databases offer. There are skip indexes for specific cases and they complement rather than replace the sorting key, so the design conversation is about physical ordering rather than about which columns to index afterwards.
Why does insert frequency matter?
Because each insert creates parts that must be merged in the background. Many small inserts generate merge work that competes with queries, so batching — thousands of rows at a time rather than one — is a requirement rather than an optimisation.
When are materialised views appropriate?
Where the same aggregation is computed repeatedly over the same data. They calculate on insert rather than on query, which turns a recurring expensive scan into a lookup — at the cost of the aggregation being fixed at write time.
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.
