    This document describes how to create and view an instance in the CKafka Console.


    Creating instance

    1. Log in to the CKafka Console.
    2. On the CKafka instance list page, click Create to enter the instance purchase page.
    3. On the CKafka instance purchase page, set the configuration information for purchase.
      • Billing Mode: pay-as-you-go billing is supported.
      • Region: select a region close to the physical partition
      • AZ: select a purchasable partition
      • Product Specification: select an appropriate model based on the peak bandwidth and disk capacity
      • Message Retention: a period in minutes ranging from 1 minute to 90 days


        After the message retention period is set, messages will be deleted after expiration. Messages are deleted in batches based on CKafka segments but not immediately. Currently, the segment size is 1 GB, and if a segment is less than 1 GB, it will not be deleted. Therefore, if the retention period is set to 1 minute, but the data size of the segment cannot be accumulated to 1 GB in 1 minute, this period will not take effect, and you are recommended to increase the period depending on the speed of data accumulation.

      • Quantity: 1–20
    4. Click Buy Now to complete the instance creation process.
