Terms in this definition
- Immutability
An optional setting for OneLake diagnostics that locks diagnostic logs as write-once, read-many for a chosen retention period, so nobody can edit or delete them. Once set, the period cannot be reduced or undone.
- CRUD
Shorthand for create, read, update and delete, the four basic things you do with data. Data-plane roles in Azure Cosmos DB, for instance, authorise those operations on items.
