there maybe meet some errant operation while maintain working. When errant transaction happened on source database, the data will be lost both at source/target database with processing CDC replication .
during maintain some bank systems, customer need that CDC have the more flexible configuration to support the time-deployed replication for some subscription.
If CDC can support time-delayed replication, support set the delay timeslot by configuration, for example config 3-5 hours by customer, the lost data for source and target database can be found at target database and restore back to source database quickly and system will rework quickly, instead of back from backup system or other way with long time, so the data can be recovered and got from target database.
this feature will helpful to customer maintain working, for example, some application configuration data or period updating data in business system which not oftenly changing or updating. very helpful to position CDC with easy using and flexible replication option.
|Who would benefit from this IDEA?||all IBM key customers using CDC as data replication platform.|
|Priority Justification||in production, the requirement of CDC is very helpful because the cycle of changing/updating is more frequent iterations. very good feature to support new seller and expand CDC more scenarios in customer environment.|
|Client Name||China MinSheng Bank， and other China Banks for example People Bank of China etc.|
How should it work?
need CDC have the more flexible configuration option to support the time-deployed replication for some subscription. If CDC can support time-delayed replication, support set the delay timeslot by configuration, for example config 3-5 hours by customer, the lost data can be found at target database and restore back quickly, instead of back from backup system or other way with long time, so the data can be recovered and got from target database.
