        `<https://www.elastic.co/guide/en/elasticsearch/reference/8.4/ccr-put-auto-follow-pattern.html>`_

        :param name: The name of the collection of auto-follow patterns.
        :param remote_cluster: The remote cluster containing the leader indices to match
            against.
        :param follow_index_pattern: The name of follower index. The template {{leader_index}}
            can be used to derive the name of the follower index from the name of the
            leader index. When following a data stream, use {{leader_index}}; CCR does
            not support changes to the names of a follower data stream’s backing indices.
        :param leader_index_exclusion_patterns: An array of simple index patterns that
            can be used to exclude indices from being auto-followed. Indices in the remote
            cluster whose names are matching one or more leader_index_patterns and one
            or more leader_index_exclusion_patterns won’t be followed.
        :param leader_index_patterns: An array of simple index patterns to match against
            indices in the remote cluster specified by the remote_cluster field.
        :param max_outstanding_read_requests: The maximum number of outstanding reads
            requests from the remote cluster.
        :param max_outstanding_write_requests: The maximum number of outstanding reads
            requests from the remote cluster.
        :param max_read_request_operation_count: The maximum number of operations to
            pull per read from the remote cluster.
        :param max_read_request_size: The maximum size in bytes of per read of a batch
            of operations pulled from the remote cluster.
        :param max_retry_delay: The maximum time to wait before retrying an operation
            that failed exceptionally. An exponential backoff strategy is employed when
            retrying.
        :param max_write_buffer_count: The maximum number of operations that can be queued
            for writing. When this limit is reached, reads from the remote cluster will
            be deferred until the number of queued operations goes below the limit.
        :param max_write_buffer_size: The maximum total bytes of operations that can
            be queued for writing. When this limit is reached, reads from the remote
            cluster will be deferred until the total bytes of queued operations goes
            below the limit.
        :param max_write_request_operation_count: The maximum number of operations per
            bulk write request executed on the follower.
        :param max_write_request_size: The maximum total bytes of operations per bulk
            write request executed on the follower.
        :param read_poll_timeout: The maximum time to wait for new operations on the
            remote cluster when the follower index is synchronized with the leader index.
            When the timeout has elapsed, the poll for operations will return to the
            follower so that it can update some statistics. Then the follower will immediately
            attempt to read from the leader again.
        :param settings: Settings to override from the leader index. Note that certain
            settings can not be overrode (e.g., index.number_of_shards).
