# Introduction Refactored the api `validateBuildAndRunWorkspaceMigration` to be require less configuration but to infer required args dynamically depending on provided metadata maps to compare ## `inferDeletionFromMissingEntities` Is not dynamically computed avoiding any miss configuration issue and any missleading devxp ## Maps computation Making only one call to redis to build both dependency and to be compared entity maps. It does not matter to avoid passing a about to compared flat entity maps to could also be a depedency, it's handled directly in the builder setup optimistic cache logic Please note that the flat maps used for the service input transpilation might differ from the one that we will dynamically compute and inject in the builder. Leading to do 2 redis calls but also race condition prone validation error We prefer that this occurs at the builder rather than at the runner level as the pg instance is not cache and reflect the real state of a given workspace In a nutshell, there's a possible race condition between cache invalidation and computation in both service input transpilers and builder but we're totally ok with that

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
