As always, the priority remains the same: **reproducible, accurate data first**, and it has to be fast. With the database now north of **100 GB**, individual tables exceeding **30 million rows**, and creeping towards **a billion individual data points**, keeping things responsive is… non-trivial. At this scale, every additional chart is basically an argument with physics. Most of the wait-time issues are now largely handled via an army of background cache workers that pre-compute things *before* you ask for them. The end result is that almost everything on the site now loads close to instantly, which is generally preferable to staring at a spinner questioning your life choices. As the most frequent data is made available once per month, I can afford to cache it all and only cache again when there is new data to offer you. ### **EPC** Mostly speed improvements here. EPC now has its own section and also integrates into individual property searches where a valid certificate exists. Worst case, finding an EPC takes around **980 ms**, depending on your connection, slightly slower on mobile, as this data can’t be fully cached without doing something truly unpleasant. ### **Property Dashboard** Now fully cached. Therefore fast. As much information as the Land Registry realistically provides is summarised here. It’s not rich data, but everything it *does* contain is now surfaced in one place without unnecessary waiting. ### **Property Area Search** A new section, and now fully cached. This allows Land Registry data to be viewed by area, from smallest to largest: - Locality - Town / City - District - County You can find the search [here](../property/search). It is quicker than before, which is the main point. ### **Individual Property Search** Tidied up and reorganised based on suggestions. It was already fast, but now it should at least *look* like it knows what it’s doing. ### **Prime, Ultra Prime and Outer Prime** These pages have been expanded to include everything usable from the Land Registry data, including price breakdowns by property type: - Flats - Detached - Semi-detached - Terraced Additional charts now show: - Existing vs new-build sales - Leasehold vs freehold sales The **Top 3 Sales** chart is now properly interactive, you can hover over each point and see full details, including the postcode, should you feel the urge to investigate further. ### **Repossessions** Yes, fine, I got too clever and built an over-engineered dashboard that nobody liked. Clearly my fault. This has now been rebuilt and simplified. There’s a clean summary view with high-level data, plus a search box that lets you drill down into **Local Authority level** figures. That’s the lowest level the data supports, so no, you can’t go smaller. ### **General Tidying** - The **House Price Index (HPI)** section has been cleaned up with simpler, more readable charts covering the UK, England, Wales, Scotland and Northern Ireland. - The **new-build comparison** has been simplified to show total new-build vs existing sales, plus whether each increased or decreased year-on-year. No unnecessary decoration. ### **Not really relevant, but I’ll say it anyway** I’ve also built a new admin dashboard that lets me update all market-stress indicators quickly as soon as new data drops. Nobody will ever see this, but it makes my life easier, which matters. That’s the last week covered. More updates/changes are coming next week.
