Tunnel Service provides tunnels for full and incremental data consumption, orderly incremental data consumption, consumption latency monitoring, and horizontal scaling of data consumption capabilities.
Tunnels for full and incremental data consumption
Tunnel Service allows you to consume incremental data, full data, and full and incremental data simultaneously.
Orderly incremental data consumption
Tunnel Service sequentially distributes incremental data to one or more logical partitions based on the write time. Data in different partitions can be consumed simultaneously.
Consumption latency monitoring
Tunnel Service allows you to call the DescribeTunnel operation to view the latency (time point) of the consumed data on each client. Tunnel Service also allows you to monitor data consumption of tunnels in the Tablestore console.
Horizontal scaling of data consumption capabilities
Tunnel Service supports automatic load balancing among logical partitions. With this feature, you can add more tunnel clients to accelerate data consumption.
