Enum RedisClusterTransactions

java.lang.Object
java.lang.Enum<RedisClusterTransactions>
io.vertx.redis.client.RedisClusterTransactions
All Implemented Interfaces:
Serializable, Comparable<RedisClusterTransactions>
public enum RedisClusterTransactions extends Enum<RedisClusterTransactions>
Define how Redis transactions are handled in a clustered Redis client.

This is only meaningful in case of a cluster Redis client.

  • Enum Constant Details

    • DISABLED

      public static final RedisClusterTransactions DISABLED
      Redis transactions are not supported in the cluster. Transaction commands lead to an error.

    • SINGLE_NODE

      public static final RedisClusterTransactions SINGLE_NODE
      Redis transactions are supported in the cluster, but only when they target a single node. The MULTI command is queued and is only issued when the next command is executed. This next command binds the connection to the corresponding node of the Redis cluster (so it should have keys, otherwise the target node is random). All subsequent commands are targeted to that node. If some of the subsequent commands have a key that belongs to another node, the command fails on the server side.

      If WATCH is used before MULTI, its key(s) determine to which node the connection is bound and the subsequent MULTI is not queued. If WATCH keys belong to multiple nodes, the command fails on the client side.

  • Method Details

    • values

      public static RedisClusterTransactions[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static RedisClusterTransactions valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
