The following example loads raw JSON data into a single landing table named raw. Two tasks query table streams created on the raw table and insert subsets of rows into multiple tables. Because each task consumes the change data capture records in a table stream, multiple streams are required....

The buffer workers temporarily store data before sending it to Snowflake, acting as intermediaries to handle the data stream more efficiently. Adjust this value based on system performance and data transmission requirements. 256 Query Mode Allows you to choose between synchronous or asynchronous request...

Snowflake File format is a named database object that can be used to simplify the process of accessing the staged data and streamlines loading data into and unloading data out of database tables. A Snowflake File format encapsulates information of data files, such as file type (CSV, JSON,...
Similar to water flowing in a stream, data in a dynamic table pipeline flows from the root downstream toward the leaf dynamic table: DT2 is described as downstream of DT1 because it depends on that dynamic table, and as upstream of DT3, which depends on it. DT3 is downstream of both ...
