1. statement_info is account-level accessable, but all account's data is in one phy table. Hard to count each account's storage usage, and also leads to scan others accounts' data.

2. current index is `cluster by (request_at, account)`, while the correct one shoulde be `cluster by(account, request_at)` or `cluster by (request_at)`

Why is this needed ?

solution 1

seprate accounts' data into individul table.

solustion 2

corrent the cluster by index define

基于 mo 1.3.0 不兼容升级，重构相关的 cluster by 或 partition key

18936 先忽略 system.statement_info, system_metrics.metric 的schema 校验.

等待 mo 1.3 完成不兼容升级，再重新打开。
