ClickHouse Implementation in Belfast
Implementing ClickHouse for Belfast 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 Belfast — 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 County Antrim?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Belfast and the surrounding County Antrim area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Belfast businesses do you usually work with?
- Fintech and security-accredited systems, plus trading platforms that handle the specific customs position on goods. Beyond that we work across Fintech, Cyber Security, Film & Media, Manufacturing and Higher Education.
- Do you cover the areas around Belfast?
- Yes — we work throughout Northern Ireland, including Lisburn, Bangor, Newry. Belfast is an urban area of roughly 345,000+, and we take on work across the wider County Antrim region rather than the city boundary alone.
