A caching option set per VM disk. ReadOnly is the data-disk default and safe for reads, ReadWrite risks losing cached writes if the host fails, and None suits write-heavy disks.
- New-AzResourceLock
Locks a subscription, resource group or resource; choose
ReadOnlyorCanNotDeletewith-LockLevel. - Resource locks
Locks, at ReadOnly or CanNotDelete level, that stop management-plane changes. They place no limits on where resources go or how large they are, and data-plane work such as blob reads and writes carries on regardless.
- Table-valued parameter
A parameter, based on a user-defined table type, that sends a set of rows to a stored procedure or function in a single call. It can only be read, so it has to be marked READONLY.
