For example, DDL statements that affect the source object during a cloning operation can alter the outcome or cause errors. Cloning is not instantaneous, particularly for large objects (databases, schemas, tables), and does not lock the object being cloned. As such, a clone does not reflect a...
Before we dive into an example pipeline, we’ll briefly go over the concept ofChange Data Capture(CDC). CDC is the process of tailing the database’s change logs, turning database events such as inserts, updates, deletes, and relevant DDL statements into a stream of immutable events, and...
transaction, avoid DDL statements on the same object in different sessions for the duration of the transaction. For example, don’t run INSERT statements on a table in one session while simultaneously running a DDL statement that changes the data type of a column in the table in a different ...

For example, don’t use a mix of base_table, schema.base_table, and database.schema.base_table in the same select_statement. Instead, choose one of these forms (e.g. database.schema.base_table), and use this consistently throughout the select_statement. Do not query stream objects in...
