Database Transmission Service (DTS) performs various checks on databases before creating or configuring migration or synchronization tasks for Elasticsearch. This topic introduces the details of check items.
Item | Database type | Check scope | Level | Check content | Remarks |
Data connectivity | Target database | All synchronization | Error | Check if connecting to the target database Elasticsearch succeeds. | None |
Elasticsearch instance version | Target database | All synchronization | Error | Check whether the Elasticsearch instance version is greater than or equal to 6.0. If it is less than 6.0, the pre-check fails. | None |
Target database index | Target database | All synchronization | Warn | Check whether the indexes already exist in the target database Elasticsearch. | None |
Elasticsearch health status | Target database | All synchronization | Error | Check the health status of the target database Elasticsearch. If the state is Red, pre-check fails. | None |
