    Capacity Estimation

    After selecting the cluster type, you need to estimate instance specifications actually needed by your business, including the compute and storage specifications.
    Compute specifications: In TDMQ for Apache Pulsar Pro, the compute specifications refer to the upper limits of TPS for receiving and sending messages and bandwidth for this cluster instance. You need to select appropriate compute specifications based on actual business operations.
    Storage specifications: You can estimate the required storage space based on your projected message volume and size. In a pro cluster with a fixed storage form, the storage capacity is fixed with a monthly subscription. In a pro cluster with an elastic storage form, storage can be used on a pay-as-you-go basis, but it should be noted that the maximum storage limit varies among different cluster specifications.
    The message storage in TDMQ for Apache Pulsar Pro defaults to a 3 replica mode. Be aware during estimation.
