[GitHub] [shardingsphere] TeslaCN opened a new issue, #26016: All tables' row counts in shardingsphere.sharding_table_statistics are always 0
TeslaCN opened a new issue, #26016:
URL: https://github.com/apache/shardingsphere/issues/26016
## Bug Report
### Which version of ShardingSphere did you use?
5.3.2
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Row counts in `shardingsphere.sharding_table_statistics` are equal to `information_schema.tables`.
### Actual behavior
### Reason analyze (If you can)
`org.apache.shardingsphere.sharding.metadata.data.ShardingStatisticsTableCollector` didn't handle logic data source and physical data source properly while using ShardingRule + ReadwriteSplittingRule.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
