Modifies an existing table or view index (rowstore, columnstore, or XML) by disabling, rebuilding, or reorganizing the index; or by setting options on the index.
The Index Entry Offset Table (IEOT) is used to help address the CPU cost of loading the index by enabling multi-threading the process of converting cache entries from the on-disk format to the in-memory format. The signature for this extension is { 'I', 'E', 'O', 'T' }. ...

Navigate to the Delta table you want to use. Click the Create button at the upper-right, and select Vector search index from the drop-down menu. Use the selectors in the dialog to configure the index. Name: Name to use for the online table in Unity Catalog. The name requires a three...
Large numbers of indexes on a table affect the performance of INSERT, UPDATE, DELETE, and MERGE statements because all indexes must be adjusted appropriately as data in the table changes. For example, if a column is used in several indexes and you execute an UPDATE statement that modi...
Another index stores the temperature delta and the maximum temperature. The result of the delta is sorted in descending order. A query could use this index to quickly find table rows where the temperature delta is less than 20 and the maximum temperature is greater than 75. ...

Change in BMI at age = t as a function of prior level of cognitive ability can thus be written as: $$\Delta_{BMIt} = \alpha_{BMI} \times BMI_{s} + \beta_{BMI} \times BMI_{t - 1} + \gamma_{COG \to BMI} \times COG_{t - 1}$$ ...
Database Mirroring (preview)Users can connect to and continuously replicate data from an external database into Fabric OneLake via Delta tables. Once in OneLake, users can operationalize the data (i.e., run analytics with Spark, execute notebooks, visualize through Power BI Reports, etc.). Th...
