multi-level catalog 多级目录
Notice that data from all fragments is sorted together to form table level statistics, which is encoded and stored in the system catalog sysdistrib.
注意,来自所有片段的数据被一同存储,形成了表级别的统计数据,被编码并存储到系统目录sysdistrib中。
Consider increasing logical logs to account for the additional fragment-level statistics rows in the sysfragdist catalog.
考虑增加逻辑日志来存放sysfragdist目录中额外的片段级统计行。
Users can look up the procedure attributes such as routine schema, specific name, number of parameters, deterministic, external action, and access level using the SYSCAT.ROUTINESFEDERATED catalog.
用户可以使用 SYSCAT.ROUTINESFEDERATED 编目查找过程属性,比如例程模式、特定名称、参数数量、确定性、外部动作和访问级别。
