弃用

主动-主动数据库持久性

用于主动-主动数据库数据持久性的快照选项将在 Redis Enterprise Software 的未来版本中弃用。如果您有使用快照暂留的主动-主动数据库，请切换到 AOF 暂留。用crdb-cli为此，请执行以下作：

crdb-cli crdb update --crdb-guid <CRDB_GUID> --default-db-config '{"data_persistence": "aof", "aof_policy":"appendfsync-every-sec"}'

TLS 1.0 and TLS 1.1

TLS 1.0 and TLS 1.1 connections are considered deprecated in favor of TLS 1.2 or later.

Please verify that all clients, apps, and connections support TLS 1.2. Support for the earlier protocols will be removed in a future release.

Certain operating systems, such as RHEL 8, have removed support for the earlier protocols. Redis Enterprise Software does not support connection protocols that are not supported by the underlying operating system.

3DES encryption cipher

The 3DES encryption cipher is considered deprecated in favor of stronger ciphers like AES.

Please verify that all clients, apps, and connections support the AES cipher. Support for 3DES will be removed in a future release.

Certain operating systems, such as RHEL 8, have already removed support for 3DES. Redis Enterprise Software cannot support cipher suites that are not supported by the underlying operating system.

Known limitations

Feature limitations

  • RS54131 Running the QUIT command on a TLS connected database closes connection and does not return a +OK reply

  • An intermittent issue can occur where a CRDB process becomes stuck in a restart loop. If this issue occurs while upgrading to Redis Enterprise Software version 6.2.18, please upgrade to the latest version 6.4.2-69 or contact support.

  • RS40641 - API requests are redirected to an internal IP in case the request arrives from a node which is not the master. To avoid this issue, use rladmin cluster config to configure handle_redirects or handle_metrics_redirects.

  • RS51144, RS102128 - Active-Active: To start successfully, the syncer (crdt-syncer) must connect to all sources. In multi-cluster configurations (more than 2 A-A clusters participating), in some cases, if one or more of the clusters is not available, A-A replication will be down.

Installation limitations

Several Redis Enterprise Software installation reference files are installed to the directory /etc/opt/redislabs/ even if you use custom installation directories.

As a workaround to install Redis Enterprise Software without using any root directories, do the following before installing Redis Enterprise Software:

  1. Create all custom, non-root directories you want to use with Redis Enterprise Software.

  2. Mount /etc/opt/redislabs to one of the custom, non-root directories.

Upgrade limitations

Before you upgrade a cluster that hosts Active-Active databases with modules to v6.2.18, perform the following steps:

  1. Use crdb-cli to verify that the modules (modules) and their versions (in module_list) are as they appear in the database configuration and in the default database configuration:

    crdb-cli crdb get --crdb-guid <crdb-guid>

  2. From the admin console's redis modules tab, validate that these modules with their specific versions are loaded to the cluster.

  3. If one or more of the modules/versions are missing or if you need help, contact Redis support before taking additional steps.
