customize their ShardingSphere just like building with LEGO blocks. ShardingSphere became an Apache Top‐Level Project on April 16, 2020. Welcome to interact with community via the official mail list and shadow database and so on. The user‐defined feature can be fully customized and extended for the top‐level interface defined by Apache ShardingSphere without changing kernel codes. 3.4. Pluggable Architecture not support rownum + BETWEEN pagination for now. • SQLServer Support TOP + ROW_NUMBER() OVER pagination: SELECT * FROM (SELECT TOP (?) ROW_NUMBER() OVER (ORDER BY o.order_id DESC) AS rownum, * FROM t_order

ingSphere provides distributed database solutions that can scale out computing and stor‐ age levels on top of the underlying database. Dis‐ tributed Trans‐ action Transactional capability is key to ensuring the databases’core technologies. ShardingSphere provides distributed transaction ca‐ pability on top of a single database, which can achieve data security across underlying data sources.

?) WHERE rownum > ? 目前不支持 rownum + BETWEEN 的分页方式。 • SQLServer 支持使用 TOP + ROW_NUMBER() OVER 配合进行分页： SELECT * FROM (SELECT TOP (?) ROW_NUMBER() OVER (ORDER BY o.order_id DESC) AS rownum, * FROM t_order 的方式进行分页。由于 Hibernate 自动生成的 SQLServer 分 页语句使用了 WITH 语句，因此目前并不支持基于 Hibernate 的 SQLServer 分页。目前也不支持使用两 个 TOP + 子查询的方式实现分页。 • MySQL, PostgreSQL MySQL 和 PostgreSQL 都支持 LIMIT 分页，无需子查询： SELECT * FROM t_order o ShardingSphere- Proxy 共同使用。 # 默认值：logic_db schemaName (?): mode: dataSources: rules: - !FOO_XXX ... - !BAR_XXX 5.1.
