Incremental refresh settings clarification
Is this the correct interpretation of my setting: keep the past 10 years data look for the rows created in the past 1 year of the past 1 year data, refresh rows where updated column changedNot exactly. What is actually means is
- keep 8 or 9 static (cold) yearly partitions
- no warm partitions (as there is no granularity difference)
- 1 or 2 hot yearly partitions. 2023 will be refreshed as long as parts of it are still "within one calendar year from today". NOTE: Incremental refresh only works with regular calendar boundaries
"Detect Data Changes" will incur additional storage cost as your partitions will be canaried (duplicated) so the Power BI service can decide when to update them. Not recommended.
"Only refresh complete years" will exclude the current year from refresh. Not sure why you would want that.
