Share

In the Ultra Transcenders books

DP-750

Each book explains Share in context, with comparison tables and the common traps.

Terms in this definition

• OpenSharing

  An open protocol and platform from Azure Databricks for sharing data and AI assets securely, whether with another metastore (Databricks-to-Databricks) or with recipients who don't use Databricks (open sharing).

• Container

  Something that groups data. Blob Storage containers sit inside a storage account and hold blobs much as folders hold files; Cosmos DB containers hold items and set the scope for partitioning and throughput.

• 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.

• Metastore

  The highest-level Unity Catalog container, holding metadata and permissions for a single cloud region. Each region has only one, which every workspace in that region shares, and it is not meant to be the usual boundary for isolating data.

• Architecture Definition Document

  A key deliverable bringing together the main architecture artifacts across the four domains for every relevant state: baseline, transition and target. It sets out, in qualitative terms, what the architect intends.

• Schema

  The middle part of a Unity Catalog name (catalog.schema.table), grouping tables, views, volumes, functions and models inside a catalog. A grant on it covers everything in it now and later, and nothing inside can be reached without USE SCHEMA.

• ALL

  A DAX function that ignores any filters and gives back every row of a table or every value of the named columns. Used within CALCULATE, it works as a modifier that clears filters, although REMOVEFILTERS states that intent more clearly where it is available.

Related terms

• Access-based enumeration

  When turned on for an SMB share or a DFS namespace, users only see the files, folders and links they're allowed to read; everything else is hidden from them.

• Accuracy (classification metric)

  Overall measure for a classification model: the share of all test cases it predicts correctly.

• Active committer

  How GHAS for Azure DevOps is charged. Each person counts once if they've pushed to any repository with it switched on within 90 days, even when several organisations share one Azure subscription.

• Allow gateway transit

  Peering option set on the hub, which owns the gateway, so that peered VNets can share its ExpressRoute or VPN gateway. The spoke sets Use remote gateways to match; on a VNet lacking a gateway the option has no effect.

• Authoritative upload

  Option for an Azure File Sync server endpoint pre-seeded with the share's data, letting the server's files overwrite the cloud copy on upload.

• Azure Backup reports

  Reporting for Azure Backup, fed by diagnostic settings on each vault. Log Analytics workspaces receiving the data may be in any region, whereas a storage account target has to share the vault's region.

• Azure Files backup

  Azure Backup for file shares, using a Recovery Services vault that must share the storage account's region. Schedules are either daily or hourly; hourly ones repeat every 4, 6, 8 or 12 hours, with 1 and 2 added in newer policies.

• Azure Files OAuth over REST

  Capability allowing Microsoft Entra users, groups and managed identities to use OAuth tokens against the FileREST data API. The roles that grant it carry readFileBackupSemantics or writeFileBackupSemantics; the SMB share roles don't apply.
