Transferring Logs to DIS

DIS provides both log storage and big data analysis. It can perform offline analysis, and transmit a large number of log files to the cloud for backup, query, and machine learning. You can also use it for data recovery and fault analysis on data losses or exceptions. During transfer, a large number of small text files can be merged into large files to accelerate data processing. Select DIS to transfer logs based on your service scenario.
  • You are advised to transfer logs to DMS.
  • Currently, this function is available only in regions CN North-Beijing4, CN North-Beijing1, CN East-Shanghai2, CN South-Guangzhou, CN-Hong Kong, and AP-Singapore. For other regions, you need to submit a service ticket to DIS. For details, see Submitting a Service Ticket.

Prerequisites

    You will be billed for the storage you use in DIS. For details, see Product Pricing Details.
