Pepperwind, a fictional company dataset with 223 tables and 79M rows

Hi HN. I'm a software engineer, building Misata Studio.

Pepperwind Trading Co, is a fictional spice and tea trader from Kochi, selling in India, Europe and the US for three years. It has a storefront, a subscription club, a warehouse, ledgers in 3 currencies, support, CRM, marketing, product analytics, HR, payroll and company mail. It is around 223 tables, 79 M rows that is around 7GB of parquet files. It was made with the help of the backend engine behind misata studio.

What I found while I was researching about the synthetic dataset needs was that products that is being built for interconnected systems or analytical solutions that serve organisations often lack a real usable test dataset that is realistic enough to verify the performance and workflows accurately. And most of the time synthetic datasets don't care about entity resolution, same customers existing in different places and in different IDs, FKs pointing at rows that doesnt exist, the values might not match exactly and this is a mess when it comes to finances of the datasets. There are plenty out there, but a single heavy and massive dataset is rare. It was from a similar pain that the idea behind building misata was born.

Some things I was focussed on while building Pepperwind was for it to have unique and valuable usability for different usecases, like: - The books balance in the ledger. - 20 incidents planted in. Courier failure in Diwali, Dutch VAT charged on EU invoices, a referral fraud, price rise that pushes subscription churn etc. I made these incidents consistent across the systems. - It ships with 92 KPIs and their values each month, along with 420 questions that can be asked against the dataset.

Misata is a from scratch multi-table synthetic data generation project with an open-source python library and a web tool I am developing for prompt to dataset generation. I had posted about this in December and have come a long way since then https://news.ycombinator.com/item?id=46289055.

The page lets you explore a small slice of the dataset in your browser and you can follow a single customer through every system. The preview is free and the full version is paid for now, to cover the building cost ($30). Listed in huggingface under CC by 4.0 license: https://huggingface.co/datasets/misatadata/pepperwind .

I would like to reach out to people across dozens of use cases. What would you use it for and how could this or another dataset similar to this help you build your product/solution?

Windows

Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Previous and Next buttons read up and down the list in the same window.

A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Previous and Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

The list

The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

Collections are named lists of stories. Story > Add to collection files the story in front into one or more of them, and the Collections feed shows them all or one at a time; the menu that chooses collections also creates, renames, and deletes them. A note is your own text on a story. Choose Add note in a story's toolbar to write one; it saves as you type. Rows with a note carry the note mark, and the Notes feed lists every noted story and searches the text of your notes.

Browsing view

View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page is a one-off action that does not change your saved default. Use the Windowed selector to return an article to a window. Direct page links always open as pages.

Applets

The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser anonymously and is included in retained applet state when signed in.

Find

Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

About

YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Without a YAVCHN account, your data stays in this browser. When signed in, pins, collections, notes, blocked domains, and retained reading state are stored with your account and synchronized across devices. Hidden stories and layout stay in this browser. The privacy policy has the details.
