| Presentation: | How Power Query Thinks: Taking the Mystery Out of Streaming and Query Folding |
| Date: | June 6th |
| Time: | 6:30 – 8:30 PM ET |

| Overview: | How does Power Query produce the table data your expressions ask it to output? Query folding is one key concept—where behind the scenes, part or all of your M code may be rewritten into the data source’s native query language then offloaded to the source for execution. Streaming, though perhaps a less familiar term, is even more fundamental, as it describes how table data (as well as list and binary data) flows between functions in M.
Understand these concepts, and you’ll be better positioned to write more efficient mashups, debug problems and avoid unexpected variability in results. Join this session to learn about these key concepts—in a nutshell, to learn about How Power Query Thinks when you ask it to produce table data!
