    • Method Detail

      • hasOpTimeout

        boolean hasOpTimeout()
         Per-operation timeout in milliseconds. The timer starts when the first
 command of a pipeline is written to the backend connection. Each response received from Redis
 resets the timer since it signifies that the next command is being processed by the backend.
 The only exception to this behavior is when a connection to a backend is not yet established.
 In that case, the connect timeout on the cluster will govern the timeout until the connection
 is ready.
        .google.protobuf.Duration op_timeout = 1 [(.validate.rules) = { ... }
        Returns:
        Whether the opTimeout field is set.

      • getOpTimeout

        com.google.protobuf.Duration getOpTimeout()
         Per-operation timeout in milliseconds. The timer starts when the first
 command of a pipeline is written to the backend connection. Each response received from Redis
 resets the timer since it signifies that the next command is being processed by the backend.
 The only exception to this behavior is when a connection to a backend is not yet established.
 In that case, the connect timeout on the cluster will govern the timeout until the connection
 is ready.
        .google.protobuf.Duration op_timeout = 1 [(.validate.rules) = { ... }
        Returns:
        The opTimeout.

      • getEnableHashtagging

        boolean getEnableHashtagging()
         Use hash tagging on every redis key to guarantee that keys with the same hash tag will be
 forwarded to the same upstream. The hash key used for determining the upstream in a
 consistent hash ring configuration will be computed from the hash tagged key instead of the
 whole key. The algorithm used to compute the hash tag is identical to the `redis-cluster
 implementation <https://redis.io/topics/cluster-spec#keys-hash-tags>`_.
 Examples:
 * '{user1000}.following' and '{user1000}.followers' **will** be sent to the same upstream
 * '{user1000}.following' and '{user1001}.following' **might** be sent to the same upstream
        bool enable_hashtagging = 2;
        Returns:
        The enableHashtagging.

      • getEnableRedirection

        boolean getEnableRedirection()
         Accept `moved and ask redirection
 <https://redis.io/topics/cluster-spec#redirection-and-resharding>`_ errors from upstream
 redis servers, and retry commands to the specified target server. The target server does not
 need to be known to the cluster manager. If the command cannot be redirected, then the
 original error is passed downstream unchanged. By default, this support is not enabled.
        bool enable_redirection = 3;
        Returns:
        The enableRedirection.

      • getMaxBufferSizeBeforeFlush

        int getMaxBufferSizeBeforeFlush()
         Maximum size of encoded request buffer before flush is triggered and encoded requests
 are sent upstream. If this is unset, the buffer flushes whenever it receives data
 and performs no batching.
 This feature makes it possible for multiple clients to send requests to Envoy and have
 them batched- for example if one is running several worker processes, each with its own
 Redis connection. There is no benefit to using this with a single downstream process.
 Recommended size (if enabled) is 1024 bytes.
        uint32 max_buffer_size_before_flush = 4;
        Returns:
        The maxBufferSizeBeforeFlush.

      • hasBufferFlushTimeout

        boolean hasBufferFlushTimeout()
         The encoded request buffer is flushed N milliseconds after the first request has been
 encoded, unless the buffer size has already exceeded ``max_buffer_size_before_flush``.
 If ``max_buffer_size_before_flush`` is not set, this flush timer is not used. Otherwise,
 the timer should be set according to the number of clients, overall request rate and
 desired maximum latency for a single command. For example, if there are many requests
 being batched together at a high rate, the buffer will likely be filled before the timer
 fires. Alternatively, if the request rate is lower the buffer will not be filled as often
 before the timer fires.
 If ``max_buffer_size_before_flush`` is set, but ``buffer_flush_timeout`` is not, the latter
 defaults to 3ms.
        .google.protobuf.Duration buffer_flush_timeout = 5;
        Returns:
        Whether the bufferFlushTimeout field is set.

      • hasMaxUpstreamUnknownConnections

        boolean hasMaxUpstreamUnknownConnections()
         ``max_upstream_unknown_connections`` controls how many upstream connections to unknown hosts
 can be created at any given time by any given worker thread (see ``enable_redirection`` for
 more details). If the host is unknown and a connection cannot be created due to enforcing
 this limit, then redirection will fail and the original redirection error will be passed
 downstream unchanged. This limit defaults to 100.
        .google.protobuf.UInt32Value max_upstream_unknown_connections = 6;
        Returns:
        Whether the maxUpstreamUnknownConnections field is set.

        boolean getEnableCommandStats()
         Enable per-command statistics per upstream cluster, in addition to the filter level aggregate
 count. These commands are measured in microseconds.
        bool enable_command_stats = 8;
        Returns:
        The enableCommandStats.

        int getReadPolicyValue()
         Read policy. The default is to read from the primary.
        .envoy.extensions.filters.network.redis_proxy.v3.RedisProxy.ConnPoolSettings.ReadPolicy read_policy = 7 [(.validate.rules) = { ... }
