Team Data Warehouse

OKR Q4

Objective

PostHog users can effortlessly bring their business data to PostHog and analyze it 🟢

• Key Results:
  • Be able to import data into data warehouse in one click from most popular SaaS tools (X, Y, Z connectors built)
  • 5 happy users/teams who have imported external data
  • Data Warehouse queries are compatible with insights hogQL

PostHog is moved over to whatever CH infrastructure we will be using for the next 1 year (at least) 🟡

• Key Results:
  • We are either on new infrastructure for EU that we host or on ClickHouse Cloud
  • Queries for large customers are performing faster
  • We can scale more easily (without James bespoke effort)

Retro

Product

• Build and test stripe connector for one click data import/sync
• Work through pricing plan for data import. (Necessary because the costs could runaway if we don't charge from the onset)

Infra

• Develop ability to feature flag / switch cluster a query is dispatched to based on team
• Further testing 720GiB x 3 cluster after downscaling
• Move over one team for testing 👀
• Cleanups from CH issues last week

High priority

Product

• Get the pricing and stripe connector through the door and deployed for beta users. All of it should be implemented by end of week
• Work through a few more connectors (TBD which ones are important)

Infra

• Complete required performance improvements with ClickHouse.cloud
• Remove EBS volumes on Prod US cluster for cost savings
