After reading "change-data-capture-another-way-to-implement-the-incremental-load2" article I have a simple question: Is it possible to use more than one "State name" for the same table? In this case, if I want to define more than one state into "cdc_states" table for the "employee" table, may I define CDC_State1, CDC_State2, and so on to feed unified data into more than one stagins tables? May I use this approach to feed data into different targets as different "processed ranges"?
Thank in advance if anybody can shed a light.

In response to your question, yes, it is possible to use multiple "State names" for the same table in the context of Change Data Capture (CDC). By defining multiple states, such as CDC_State1, CDC_State2, and so on, within the "cdc_states" table for the "employee" table, you can effectively feed unified data into multiple staging tables or different targets based on distinct "processed ranges."
This approach allows you to partition and manage the data based on specific criteria or processing requirements. Each state can represent a different subset or range of data, enabling you to perform targeted operations or transformations on those subsets.
Implementing multiple states in CDC can be beneficial for scenarios where you need to distribute or process data differently based on various conditions or criteria. It provides flexibility and scalability in handling incremental loads and managing data changes.
However, it's important to design and configure the CDC solution carefully, ensuring proper synchronization and data consistency across the different states and targets. Considerations should be made for maintaining the integrity of the data and managing the relationships between the various state tables.
Overall, using multiple "State names" in CDC offers a versatile approach to handle incremental data processing and enables you to efficiently distribute and manage data across different staging tables or targets based on specific ranges or criteria.
