Terms in this definition
- Standard deployment type
A Foundry deployment type billed per token that keeps processing of prompts and responses inside the Azure geography of the resource, meeting data residency needs at lower volumes.
- Domain
A way of grouping workspaces by area of the business, in support of a data mesh approach. Items take on their workspace's domain, letting you filter the OneLake catalog by it, and certain tenant settings can be passed to domain admins; domains have no effect on access permissions.
- Digital signature
Produced by applying the sender's private key to a hash of a message. Anyone holding the matching public key can then confirm both the sender and that nothing was altered, although the content itself stays readable.
- OVER
Gives a T-SQL window function its window: PARTITION BY, ORDER BY and, if wanted, a ROWS or RANGE frame. Rankings and running totals can then be worked out while every row is kept.
- Recipient
The Unity Catalog object for an individual or organisation that is given access to OpenSharing shares. Properties set on it can be checked with
CURRENT_RECIPIENT()to filter what that party sees.
Related terms
- DMARC
A standard that builds on SPF and DKIM: it confirms the domain shown in the From address lines up with what they checked. Domain owners use it to say how receiving servers should treat messages that fail, and where to send reports about them.
- SPF
A DNS TXT record naming which sources may send email for a domain, so receiving servers can catch spoofing. DMARC and DKIM complement it.
