Example 1: Creating a DCS Redis Instance Scenario This section describes how to create a DCS Redis instance by calling APIs. For details about how to call APIs, see Calling APIs. A 2 GB single-node DCS Redis 5.0 instance is used as an example. The instance uses the Arm CPU architecture
Common Issues of Creating DCS Instances Using an API This topic describes common issues that may occur when you create DCS instances using APIs. Table 1 Common issues of creating DCS instances Issue Solution Setting the Replica Quantity When Purchasing an Instance Using an API If
This course is intended for Huawei Cloud Developers and will introduce BCS theoretical and practice.
Blockchain Service (BCS)Service Level Agreement Print All Huawei Cloud Service Level Agreement General Terms This Service Level Agreement (this “SLA”) is an integral part of your Huawei Cloud Customer Agreement (the “Customer Agreement”). Capitalized terms used in this SLA are as
What Underlying Framework Is Used for Huawei Cloud BCS? Huawei Cloud BCS uses the Hyperledger open-source framework. Hyperledger is a blockchain open-source project hosted by the Linux Foundation to establish an underlying architecture for the distributed ledger platform oriented
Querying Big Keys and Hot Keys in a DCS Redis Instance Big keys and hot keys are common issues. This section describes the big key and hot key analysis function on the DCS console. This function monitors the key that occupies most space of a Redis instance, or that is most frequently
Commands Supported and Disabled by DCS for Memcached (Discontinued) DCS for Memcached is no longer provided. You can use DCS Redis instances instead. Memcached supports the TCP-based text protocol and binary protocol. Any clients compatible with a Memcached protocol can access DCS
Does DCS for Redis Provide Backend Management Software? No. To query Redis configurations and usage information, use redis-cli. If you want to monitor DCS Redis instance metrics, go to the Cloud Eye console or perform the following operations. Procedure Log in to the DCS console.
Can I Recover Deleted Data of a DCS Instance? If you have backed up the DCS instance, you can restore its data from the backup. However, the restoration will overwrite the data written in before the restoration. You can restore backup data to a master/standby, cluster, or read/write
Does DCS for Redis Support the INCR and EXPIRE Commands? Yes. For more information about Redis command compatibility, see Redis Command Compatibility. Parent topic: Redis Commands
Are DCS Instances Stopped or Restarted During Specification Modification? No. Specification modifications can take place while the instance is running, and do not require disabling instance resources or restarting instances. Parent topic: Instance Scaling and Upgrade
How Do I Reduce the Capacity of a DCS Instance? Table 1 lists scaling options supported by different DCS instances. Table 1 Scaling options supported by different instances Cache Engine Single-Node Master/Standby Redis Cluster Proxy Cluster Read/Write Splitting Redis 3.0 Scaling up
What Data Structures Does DCS for Memcached Support? Only the key-value structure is supported. Parent topic: Memcached Usage
What Are the Differences Between DCS for Memcached and Self-Hosted Memcached? Table 1 describes the differences between DCS for Memcached and self-hosted Memcached. Table 1 Comparing DCS for Memcached and self-hosted Memcached Item DCS for Memcached Self-Hosted Memcached Deployment
What Are the Differences Between Arm-based and x86-based DCS for Redis? DCS Redis instances support Arm and x86 CPU architectures. Arm-based Redis and x86-based Redis have the same functions and client compatibility. x86-based Redis provides higher single-CPU performance than Arm-based
Do DCS Redis Instances Limite Data Quantity? No, but the data volume cannot exceed the memory of a DCS instance. Parent topic: Feature
Does DCS for Redis Support SSL Encrypted Transmission? By default, SSL is disabled for DCS Redis 6.0 and 7.0 basic edition instances. To enable it, see . For public access to DCS Redis 3.0 instances, you can enable TLS encryption with Stunnel. For details, see the instructions on
What Do I Do If the ACS Is Acting Abnormal? Do as follows for troubleshooting: Check the hard terminal version. Log in to the web interface of the hard terminal, choose Help > Version, and check whether the software running on your hard terminal is of the recommended version. If it
Can Multiple ECSs Connect to the Same GaussDB Instance? Within the limits of database capability, multiple ECSs can connect to the same GaussDB instance. Parent topic: About GaussDB
Example 3: Deleting DCS Redis Instances in Batches Scenario This section describes how to delete DCS Redis instances in batches by calling APIs. For details about how to call APIs, see Calling APIs. Involved APIs Call APIs to perform the following steps required to delete DCS Redis
