Troubleshooting
Context Deadline Exceeded Error
ERROR CODE
rpc error: code = DeadlineExceeded desc = context deadline exceeded
This issue may be caused by extracting data over an extended timeframe. Use WHERE
or LIMIT
clauses in your SQL query to manage the size and scope of the data extraction.
- Use
WHERE
to specify the date range.SELECT * FROM your_table WHERE date_column BETWEEN '202X-01-01' AND '202X-01-31';
- Use
LIMIT
to specify the specify the maximum number of records to return.SELECT * FROM your_table LIMIT 1000;
- Combine
WHERE
andLIMIT
for more precise control. The query in this example will return the first 1000 records where the date is after January 1, 202X.SELECT * FROM your_table WHERE date_column > '202X-01-01' LIMIT 1000;
