How can I run a streaming query on a new table with tbl property: change data feed enabled?

New Contributor

In Databricks on AWS, I am trying to run a streaming query (trigger=Once) with delta.enableChangeDataFeed=true in the table definition as instructed, but this always fails with :

ERROR: Some streams terminated before this command could finish!
com.databricks.sql.transaction.tahoe.DeltaAnalysisException: Error getting change data for range [0 , 0] as change data was not recorded for version [0]. If you\'ve enabled change data feed on this table, use `DESCRIBE HISTORY` to see when it was first enabled.
Otherwise, to start recording change data, use `ALTER TABLE table_name SET TBLPROPERTIES

I tried:

  • removing checkpoints for streaming query
  • recreating the table
  • adding "": "true" to spark_conf of the compute

None of those fixed the issue. This is quite puzzling as this setting works for other tables.

What is precisely recreating a table? Maybe delta files are in the old version, which is not supporting CDC. Please also share your code.

Please first just read CDC not as a stream but as SELECT * FROM table_changes(table)

Hi @daniel e​ 

Can you try running the select command on table changes from 0th version and see if you get output?

SELECT * FROM table_changes('tableName', 0)

Also, Please share the streaming query that you are running.
