URL: https://github.com/apache/shardingsphere/issues/11462
# Input
ADD RESOURCE resource_3 (
URL="jdbc:mysql://localhost:3306/db3?serverTimezone=UTC&useSSL=false",
USER=root,
PASSWORD=123456,
PROPERTIES("maxPoolSize"=10)
);
# Steps
- Start proxy
- Execute the distSQL above
- Stop proxy and restart
- Proxy start fail
# Exception's log

# Root cause analysis
Data in zookeeper after executing the distSQL. Pay attention to the
maxPoolSize attribution. It has a string value not a integer. It makes the
issue happened.
