About incremental strategy | dbt Developer Hub This strategy doesn’t align directly with type 1 or type 2 slowly changing dimensions (SCD) It differs from SCD1, which overwrites existing records, and only loosely resembles SCD2
Slowly Changing Dimensions (SCDs) with Snapshots in dbt In this blog, we'll dive into Slowly Changing Dimensions (SCDs) and the powerful capabilities of dbt snapshots We'll walk through the process of creating dbt snapshots and highlight how
Snapshot Vs Scd2 at Anthony Brantley blog In dbt, there are 2 ways to implement an scd snapshots: Slowly changing dimension is the technique for implementing dimension history in a dimensional data warehouse The business key remains constant, but facts relating to the new Scd2 creates a new row each time the dimension data changes
PART 5B — SCD Type 1, SCD Type 2, Fact Table Loading, Spark . . . Now that you understand core transformations and dbt patterns (Part 5A), we move into the advanced mechanics of ELT pipelines This includes dimension management, fact table loading, Spark-based transformations for lakehouses, and performance tuning for merge-heavy workloads
Handling SCD Type 2 Using DBT Incremental Process Has anyone implemented this process for handling SCD Type 2 using the incremental process in dbt? Note: I am aware that SCD Type 2 can be handled using snapshots, but I need to maintain some data warehouse audit columns, which is why I am customizing my model and opting for the incremental model
jkenney0501 dbt-SCD-Incremental-models - GitHub We use type 2 SCD's to capture the history of changes A type 2 will track the entore history while remaining idempotent which is very important for building good data pieplines Below covers the two strategies that dbt uses, timestamp and check
