sp_changearticlecolumndatatype 用于替代受支持的发布服务器类型(Oracle 和 SQL Server)之间的默认数据类型映射。 若要查看这些默认数据类型映射,请执行 sp_getdefaultdatatypemapping。 sp_changearticlecolumndatatype 仅Oracle 发布服务器支持。 针对 SQL Server 发布执行此存储过程会导致错误。 sp_changearticlecolumn...
Learn about change data capture (CDC) in SQL Server and Azure SQL Managed Instance, which records insert, update, and delete activity that applies to a table.
IBUF_PAGE_SIZE_PER_FREE_SPACE 是 32 // page_size / IBUF_PAGE_SIZE_PER_FREE_SPACE 就是 512 bytes,可以看出这里只是粗糙 // 的统计 max_ins_size 是 512 bytes 的几倍,max_ins_size / 512: // - 大于 3(max_ins_size > 2048):IBUF_BIT...

其他配置:batchSize、MaxAwaitTime等。 Change Stream创建后,driver将会发送封装第一个stage为$changestream的aggreate命令给MongoDB,服务端建立成功后返回cursor给客户端。客户端调用getNext获取下一条event事件,对应driver实现是查看当前缓存队列中是否还有event,有则拉出第一条直接返回给上层,没有则发送getMore命令,然后...
