  read_timeout
  
  integer default: 2000 between: 0 2147483646
  
  An integer representing a timeout in milliseconds. Must be between 0 and 2^31-2.
  
  username
  
  string referenceable
  
  Username to use for Redis connections. If undefined, ACL authentication won’t be performed. This requires Redis v6.0.0+. To be compatible with Redis v5.x.y, you can set it to default.
  
  password
  
  string referenceable encrypted
  
  Password to use for Redis connections. If undefined, no AUTH commands are sent to Redis.
  
  sentinel_username
  
  string referenceable
  
  Sentinel username to authenticate with a Redis Sentinel instance. If undefined, ACL authentication won’t be performed. This requires Redis v6.2.0+.
  
  sentinel_password
  
  string referenceable encrypted
  
  Sentinel password to authenticate with a Redis Sentinel instance. If undefined, no AUTH commands are sent to Redis Sentinels.
  
  database
  
  integer default: 0
  
  Database to use for the Redis connection when using the redis strategy
  
  keepalive_pool_size
  
  integer default: 256 between: 1 2147483646
  
  The size limit for every cosocket connection pool associated with every remote server, per worker process. If neither keepalive_pool_size nor keepalive_backlog is specified, no pool is created. If keepalive_pool_size isn’t specified but keepalive_backlog is specified, then the pool uses the default value. Try to increase (e.g. 512) this value if latency is high or throughput is low.
  
  keepalive_backlog
  
  integer between: 0 2147483646
  
  Limits the total number of opened connections for a pool. If the connection pool is full, connection queues above the limit go into the backlog queue. If the backlog queue is full, subsequent connect operations fail and return nil. Queued operations (subject to set timeouts) resume once the number of connections in the pool is less than keepalive_pool_size. If latency is high or throughput is low, try increasing this value. Empirically, this value is larger than keepalive_pool_size.
  
  sentinel_master
  
  string
  
  Sentinel master to use for Redis connections. Defining this value implies using Redis Sentinel.
  
  sentinel_role
  
  string Must be one of: master, slave, any
  
  Sentinel role to use for Redis connections when the redis strategy is defined. Defining this value implies using Redis Sentinel.
  
  sentinel_nodes
  
  array of type record len_min: 1
  
  Sentinel node addresses to use for Redis connections when the redis strategy is defined. Defining this field implies using a Redis Sentinel. The minimum length of the array is 1 element.
  
  host
  
  string required default: 127.0.0.1
  
  A string representing a host name, such as example.com.
  
  port
  
  integer default: 6379 between: 0 65535
  
  An integer representing a port number between 0 and 65535, inclusive.
  
  cluster_nodes
  
  array of type record len_min: 1
  
  Cluster addresses to use for Redis connections when the redis strategy is defined. Defining this field implies using a Redis Cluster. The minimum length of the array is 1 element.
  
  ip
  
  string required default: 127.0.0.1
  
  A string representing a host name, such as example.com.
  
  port
  
  integer default: 6379 between: 0 65535
  
  An integer representing a port number between 0 and 65535, inclusive.
  
  ssl
  
  boolean default: false
  
  If set to true, uses SSL to connect to Redis.
  
  ssl_verify
  
  boolean default: false
  
  If set to true, verifies the validity of the server SSL certificate. If setting this parameter, also configure lua_ssl_trusted_certificate in kong.conf to specify the CA (or server) certificate used by your Redis server. You may also need to configure lua_ssl_verify_depth accordingly.
  
  server_name
  
  string
  
  A string representing an SNI (server name indication) value for TLS.
  
  cluster_max_redirections
  
  integer default: 5
  
  Maximum retry attempts for redirection.
