With Apache Spark Declarative Pipelines, engineers describe what their pipeline should do using SQL or Python, and Apache Spark handles the execution.

If a database driver supports the visualization of the execution plan, you can see the execution plan of the current query (under cursor) by pressing Ctrl+Shift+E or clicking Explain execution plan on ...

If a database driver supports the visualization of the execution plan, you can see the execution plan of the query by pressing Ctrl+Shift+E or clicking the Explain execution plan button on the main ...

For this reason, SQL Server stores execution plans in a cache (called the plan cache), so that the stored execution plan is reused for subsequent executions of a given query.

The results show that TQP achieves query execution time speedups of up to 20x over CPU-only systems and up to 5x over specialized GPU solutions. TQP also accelerates queries mixing ML predictions and ...

The execution plan is the series of logical steps that the database engine creates and uses to return the results of a given query. Reading these plans allows an administrator to identity ...

Old-school approaches to query optimization have typically considered the problem in a static context — i.e., the optimizer works independently to come up with an optimal plan that is then ...
