Call the ModifyDBEndpointReadWriteDelayThreshold API to modify the read-only latency threshold of an endpoint.
Request type
Synchronous request.
Precautions
- Read/Write separation function of the connected endpoint is enabled.
- This API only applies to the default endpoint, as read/write separation is supported only on the default endpoint.
Debug
API Explorer
You can initiate calls online through API Explorer without paying attention to the signature generation process and quickly obtain the call results.
Request parameters
