--------------------------------
Summary: The system reports error when the number of models
exported exceeds 256 at a time
Key: KYLIN-5796
URL: https://issues.apache.org/jira/browse/KYLIN-5796
Project: Kylin
Issue Type: Bug
Reporter: zhimin wu
### Root Cause
The root cause of the issue is that the size of the list passed from the
frontend exceeds the maximum limit allowed for form-urlencoded requests in
Spring. The default limit for the growth of arrays and collections in Spring's
DataBinder class is set to 256:
```java
public static final int DEFAULT_AUTO_GROW_COLLECTION_LIMIT = 256;
```
To address this issue, you may need to adjust the configuration related to the
form-urlencoded request handling in Spring to accommodate larger list sizes
being passed from the frontend. This could involve increasing the maximum limit
for auto-growing collections or implementing alternative solutions to handle
larger input data efficiently.
If you need further assistance or guidance on how to modify the configuration
to resolve this issue, please let me know.
