Why might Data Explorer in Panther crash or freeze when running a query?
Issue
When running certain queries, the Data Explorer will crash or freeze up. If I close the tab and then look at my query history, I see the query succeed, but navigating to the query results will crash again.
Resolution
To resolve this issue, try running your query again, but with the following adjustments
- Add a reasonable
LIMIT
, for exampleLIMIT
10
- If you are using
SELECT * FROM
, try to select specific columns instead for exampleSELECT specificColumn FROM
- If you are already selecting specific columns, try to reduce the number of columns returned.
Cause
This behavior is commonly caused by either a large amount of rows returned, or by a large amount of data within a row. If there is a large amount of data in a row, this can be reduced by adjusting your SELECT
statement to only include the columns that you need.
The most common scenario where this issue occurs is if you try to perform a SELECT * FROM panther_monitor.public.classification_failures
table because this table has a payload column which can contain a lot of data.
