All Implemented Interfaces:

Enclosing class:
RedisProxy.ConnPoolSettings
public static enum RedisProxy.ConnPoolSettings.ReadPolicy extends Enum<RedisProxy.ConnPoolSettings.ReadPolicy> implements com.google.protobuf.ProtocolMessageEnum
 ReadPolicy controls how Envoy routes read commands to Redis nodes. This is currently
 supported for Redis Cluster. All ReadPolicy settings except MASTER may return stale data
 because replication is asynchronous and requires some delay. You need to ensure that your
 application can tolerate stale data.
Protobuf enum envoy.extensions.filters.network.redis_proxy.v3.RedisProxy.ConnPoolSettings.ReadPolicy

  • Enum Constant Details

    • MASTER

      public static final RedisProxy.ConnPoolSettings.ReadPolicy MASTER
       Default mode. Read from the current primary node.
      MASTER = 0 [(.udpa.annotations.enum_value_migrate) = { ... }

    • PREFER_MASTER

      public static final RedisProxy.ConnPoolSettings.ReadPolicy PREFER_MASTER
       Read from the primary, but if it is unavailable, read from replica nodes.
      PREFER_MASTER = 1 [(.udpa.annotations.enum_value_migrate) = { ... }

    • REPLICA

      public static final RedisProxy.ConnPoolSettings.ReadPolicy REPLICA
       Read from replica nodes. If multiple replica nodes are present within a shard, a random
 node is selected. Healthy nodes have precedent over unhealthy nodes.
      REPLICA = 2;

    • PREFER_REPLICA

      public static final RedisProxy.ConnPoolSettings.ReadPolicy PREFER_REPLICA
       Read from the replica nodes (similar to REPLICA), but if all replicas are unavailable (not
 present or unhealthy), read from the primary.
      PREFER_REPLICA = 3;

    • ANY

      public static final RedisProxy.ConnPoolSettings.ReadPolicy ANY
       Read from any node of the cluster. A random node is selected among the primary and
 replicas, healthy nodes have precedent over unhealthy nodes.
      ANY = 4;

    • UNRECOGNIZED

      public static final RedisProxy.ConnPoolSettings.ReadPolicy UNRECOGNIZED

  • Field Details

    • MASTER_VALUE

      public static final int MASTER_VALUE
       Default mode. Read from the current primary node.
      MASTER = 0 [(.udpa.annotations.enum_value_migrate) = { ... }
      See Also:

    • PREFER_MASTER_VALUE

      public static final int PREFER_MASTER_VALUE
       Read from the primary, but if it is unavailable, read from replica nodes.
      PREFER_MASTER = 1 [(.udpa.annotations.enum_value_migrate) = { ... }
      See Also:

    • REPLICA_VALUE

      public static final int REPLICA_VALUE
       Read from replica nodes. If multiple replica nodes are present within a shard, a random
 node is selected. Healthy nodes have precedent over unhealthy nodes.
      REPLICA = 2;
      See Also:

    • PREFER_REPLICA_VALUE

      public static final int PREFER_REPLICA_VALUE
       Read from the replica nodes (similar to REPLICA), but if all replicas are unavailable (not
 present or unhealthy), read from the primary.
      PREFER_REPLICA = 3;
      See Also:

    • ANY_VALUE

      public static final int ANY_VALUE
       Read from any node of the cluster. A random node is selected among the primary and
 replicas, healthy nodes have precedent over unhealthy nodes.
      ANY = 4;
