## Context We currently have a race condition when dealing with datasource creation. This happen when multiple queries arrive at the same time (for example graphql dataloaders) and the datasource is not created yet. Since the datasource is stored in memory this can happen more often as well and they were all triggering the datasource creation at the same time. I'm trying to fix the issue with promise memoization. Now, instead of caching the datasource only, we also want to cache the promise of the datasource creation and make the creation itself synchronous. More info about promise memoization in this article for example: https://www.jonmellman.com/posts/promise-memoization Co-authored-by: Charles Bochet <charlesBochet@users.noreply.github.com>

Figma
We’ve spent thousands of hours grappling with traditional CRMs like Pipedrive and Salesforce to align them with our business needs, only to end up frustrated — customizations are complex and the closed ecosystems of these platforms can feel restrictive.
We felt the need for a CRM platform that empowers rather than constrains. We believe the next great CRM will come from the open-source community. We’ve packed Twenty with powerful features to give you full control and help you run your business efficiently.

📊 Data, Your Way: The days when the role of CRM platforms was to shift manual data entries to a database are over. Now, the data is already there. CRM 2.0 should be built around your data, allowing you to access and visualize any existing sources, not forcing you to retrofit your data into predefined objects on a remote cloud.
🎨 Effortlessly Intuitive: We set out to create something that we ourselves would always enjoy using. The main application draws inspiration from Notion, a tool known for its user-friendly interface and customization capabilities.
