Field Description
id string

ID of the Redis cluster. This ID is assigned by MDB at creation time.
folderId string

ID of the folder that the Redis cluster belongs to.
createdAt string (date-time)

Creation timestamp in RFC3339 text format.

String in RFC3339 text format.
name string

Name of the Redis cluster. The name is unique within the folder. 3-63 characters long.
description string

Description of the Redis cluster. 0-256 characters long.
labels object

Custom labels for the Redis cluster as key:value pairs. Maximum 64 per cluster.
environment string

Deployment environment of the Redis cluster.

  • PRODUCTION: Stable environment with a conservative update policy: only hotfixes are applied during regular maintenance.
  • PRESTABLE: Environment with more aggressive update policy: new versions are rolled out irrespective of backward compatibility.
monitoring[] object

Description of monitoring systems relevant to the Redis cluster.
monitoring[].
name		 string

Name of the monitoring system.
monitoring[].
description		 string

Description of the monitoring system.
monitoring[].
link		 string

Link to the monitoring system charts for the Redis cluster.
config object

Configuration of the Redis cluster.
config.
version		 string

Version of Redis server software.
config.
resources		 object
config.
resources.
resourcePresetId		 string

ID of the preset for computational resources available to a host (CPU, memory etc.). All available presets are listed in the documentation.
config.
resources.
diskSize		 string (int64)

Volume of the storage available to a host, in bytes.
config.
redisConfig_5_0		 object
config.
redisConfig_5_0.
effectiveConfig		 object

Effective settings for a Redis 5.0 cluster (a combination of settings defined in userConfig and defaultConfig).

Fields and structure of RedisConfig reflects Redis configuration file parameters.
config.
redisConfig_5_0.
effectiveConfig.
maxmemoryPolicy		 string

Redis key eviction policy for a dataset that reaches maximum memory, available to the host. Redis maxmemory setting depends on Managed Service for Redis host class.

All policies are described in detail in Redis documentation.

  • VOLATILE_LRU: Try to remove less recently used (LRU) keys with expire set.
  • ALLKEYS_LRU: Remove less recently used (LRU) keys.
  • VOLATILE_LFU: Try to remove least frequently used (LFU) keys with expire set.
  • ALLKEYS_LFU: Remove least frequently used (LFU) keys.
  • VOLATILE_RANDOM: Try to remove keys with expire set randomly.
  • ALLKEYS_RANDOM: Remove keys randomly.
  • VOLATILE_TTL: Try to remove less recently used (LRU) keys with expire set and shorter TTL first.
  • NOEVICTION: Return errors when memory limit was reached and commands could require more memory to be used.
config.
redisConfig_5_0.
effectiveConfig.
timeout		 integer (int64)

Time that Redis keeps the connection open while the client is idle. If no new command is sent during that time, the connection is closed.
config.
redisConfig_5_0.
effectiveConfig.
password		 string

Authentication password.

Value must match the regular expression [a-zA-Z0-9@=+?*.,!&#$^<>_-]{8,128}.
config.
redisConfig_5_0.
userConfig		 object

User-defined settings for a Redis 5.0 cluster.

Fields and structure of RedisConfig reflects Redis configuration file parameters.
config.
redisConfig_5_0.
