问:mysql中,对database和table的数量有限制吗?
答:没有限制,不过会受到文件系统最大文件数限制。
原文:
C.10.2 Limits on Number of Databases and Tables
MySQL has no limit on the number of databases. The underlying file system may have a limit on the number of directories.
MySQL has no limit on the number of tables. The underlying file system may have a limit on the number of files that represent tables. Individual storage engines may impose engine-specific constraints. InnoDB permits up to 4 billion tables.
本文探讨了MySQL中关于数据库和表格数量的限制问题。实际上,MySQL本身并未设定明确的数量限制,但会受到底层文件系统最大文件数的约束。InnoDB存储引擎允许高达40亿个表格。
