  [%%
   %% Networking
   %% ====================
   %%
   %% Related doc guide: http://www.rabbitmq.com/networking.html.

%% By default, RabbitMQ will listen on all interfaces, using
   %% the standard (reserved) AMQP port.
   %%
   %% {tcp_listeners, [5672]},

%% To listen on a specific interface, provide a tuple of {IpAddress, Port}.
   %% For example, to listen only on localhost for both IPv4 and IPv6:
   %%
   %% {tcp_listeners, [{"127.0.0.1", 5672},
   %%                  {"::1",       5672}]},

%% TLS listeners are configured in the same fashion as TCP listeners,
   %% including the option to control the choice of interface.
   %%
   %% {ssl_listeners, [5671]},

%% Number of Erlang processes that will accept connections for the TCP
   %% and TLS listeners.
   %%
   %% {num_tcp_acceptors, 10},
   %% {num_ssl_acceptors, 1},

%% Maximum time for AMQP 0-8/0-9/0-9-1 handshake (after socket connection
   %% and TLS handshake), in milliseconds.
   %%
   %% {handshake_timeout, 10000},

%% Set to 'true' to perform reverse DNS lookups when accepting a
   %% connection. Hostnames will then be shown instead of IP addresses
   %% in rabbitmqctl and the management plugin.
   %%
   %% {reverse_dns_lookups, false},

%%
   %% Security, Access Control
   %% ========================
   %%
   %% Related doc guide: http://www.rabbitmq.com/access-control.html.

%% The default "guest" user is only permitted to access the server
   %% via a loopback interface (e.g. localhost).
   %% {loopback_users, [<<"guest">>]},
   %%

%% Choose the available SASL mechanism(s) to expose.
   %% The two default (built in) mechanisms are 'PLAIN' and
   %% 'AMQPLAIN'. Additional mechanisms can be added via
   %% plugins.
   %%
   %% Related doc guide: http://www.rabbitmq.com/authentication.html.
   %%
   %% {auth_mechanisms, ['PLAIN', 'AMQPLAIN']},

%% Select an authentication database to use. RabbitMQ comes bundled
   %% with a built-in auth-database, based on mnesia.
   %%
   %% {auth_backends, [rabbit_auth_backend_internal]},

%% Configurations supporting the rabbitmq_auth_mechanism_ssl and
   %% rabbitmq_auth_backend_ldap plugins.
   %%
   %% NB: These options require that the relevant plugin is enabled.
   %% Related doc guide: http://www.rabbitmq.com/plugins.html for further details.

%% The RabbitMQ-auth-mechanism-ssl plugin makes it possible to
   %% authenticate a user based on the client's TLS certificate.
   %%
   %% To use auth-mechanism-ssl, add to or replace the auth_mechanisms
   %% list with the entry 'EXTERNAL'.
   %%
   %% {auth_mechanisms, ['EXTERNAL']},

%% The rabbitmq_auth_backend_ldap plugin allows the broker to
   %% perform authentication and authorisation by deferring to an
   %% external LDAP server.
   %%
   %% For more information about configuring the LDAP backend, see
   %% http://www.rabbitmq.com/ldap.html.
   %%
   %% Enable the LDAP auth backend by adding to or replacing the
   %% auth_backends entry:
   %%
   %% {auth_backends, [rabbit_auth_backend_ldap]},

%% This pertains to both the rabbitmq_auth_mechanism_ssl plugin and
   %% STOMP ssl_cert_login configurations. See the rabbitmq_stomp
   %% configuration section later in this file and the README in
   %% https://github.com/rabbitmq/rabbitmq-auth-mechanism-ssl for further
   %% details.

   %% To use the TLS cert's CN instead of its DN as the username
   %%
   %% {ssl_cert_login_from, distinguished_name},

%% TLS handshake timeout, in milliseconds.
   %%
   %% {ssl_handshake_timeout, 5000},

%% Makes RabbitMQ accept SSLv3 client connections by default.
   %% DO NOT DO THIS IF YOU CAN HELP IT.
   %%
   %% {ssl_allow_poodle_attack, false},

%% Password hashing implementation. Will only affect newly
   %% created users. To recalculate hash for an existing user
   %% it's necessary to update her password.
   %%
   %% When importing definitions exported from versions earlier
   %% than 3.6.0, it is possible to go back to MD5 (only do this
   %% as a temporary measure!) by setting this to rabbit_password_hashing_md5.
   %%
   %% To use SHA-512, set to rabbit_password_hashing_sha512.
   %%
   %% {password_hashing_module, rabbit_password_hashing_sha256},

%% Configuration entry encryption.
   %% Related doc guide: http://www.rabbitmq.com/configure.html#configuration-encryption
   %%
   %% To specify the passphrase in the configuration file:
   %%
   %% {config_entry_decoder, [{passphrase, <<"mypassphrase">>}]}
   %%
   %% To specify the passphrase in an external file:
   %%
   %% {config_entry_decoder, [{passphrase, {file, "/path/to/passphrase/file"}}]}
   %%
   %% To make the broker request the passphrase when it starts:
   %%
   %% {config_entry_decoder, [{passphrase, prompt}]}
   %%
   %% To change encryption settings:
   %%
   %% {config_entry_decoder, [{cipher,     aes_cbc256},
   %%                         {hash,       sha512},
   %%                         {iterations, 1000}]}

%%
   %% Default User / VHost
   %% ====================
   %%

%% On first start RabbitMQ will create a vhost and a user. These
   %% config items control what gets created. See
   %% http://www.rabbitmq.com/access-control.html for further
   %% information about vhosts and access control.
   %%
   %% {default_vhost,       <<"/">>},

   %% {default_user_tags, [administrator]},

%%
   %% Additional network and protocol related configuration
   %% =====================================================
   %%

%% Sets the default AMQP 0-9-1 heartbeat timeout in seconds.
   %% Values lower than 6 can produce false positives and are not
   %% recommended.
   %%
   %% Related doc guides:
   %%
   %%  * http://www.rabbitmq.com/heartbeats.html
   %%  * http://www.rabbitmq.com/networking.html
   %%
   %% {heartbeat, 60},

%% Set the max permissible size of an AMQP frame (in bytes).
   %%
   %% {frame_max, 131072},

%% Set the max frame size the server will accept before connection
   %% tuning occurs
   %%
   %% {initial_frame_max, 4096},

%% Set the max permissible number of channels per connection.
   %% 0 means "no limit".
   %%
   %% {channel_max, 0},

%% Set the max permissible number of client connections to the node.
   %% `infinity` means "no limit".
   %%
   %% This limit applies to client connections to all listeners (regardless of
   %% the protocol, whether TLS is used and so on). CLI tools and inter-node
   %% connections are exempt.
   %%
   %% When client connections are rapidly opened in succession, it is possible
   %% for the total connection count to go slightly higher than the configured limit.
   %% The limit works well as a general safety measure.
   %%
   %% Clients that are hitting the limit will see their TCP connections fail or time out.
   %%
   %% Introduced in 3.6.13.
   %%
   %% Related doc guide: http://www.rabbitmq.com/networking.html.

%%
   %% Resource Limits & Flow Control
   %% ==============================
   %%
   %% Related doc guide: http://www.rabbitmq.com/memory.html, http://www.rabbitmq.com/memory-use.html.

%% Memory-based Flow Control threshold.
   %%
   %% {vm_memory_high_watermark, 0.4},

%% Alternatively, we can set a limit (in bytes) of RAM used by the node.
   %%
   %% {vm_memory_high_watermark, {absolute, 1073741824}},
   %%
   %% Or you can set absolute value using memory units (with RabbitMQ 3.6.0+).
   %%
   %% {vm_memory_high_watermark, {absolute, "1024M"}},
   %%
   %% Supported units suffixes:
   %%
   %% k, kiB: kibibytes (2^10 bytes)
   %% M, MiB: mebibytes (2^20)
   %% G, GiB: gibibytes (2^30)
   %% kB: kilobytes (10^3)
   %% MB: megabytes (10^6)
   %% GB: gigabytes (10^9)

%% Fraction of the high watermark limit at which queues start to
   %% page message out to disc in order to free up memory.
   %% For example, when vm_memory_high_watermark is set to 0.4 and this value is set to 0.5,
   %% paging can begin as early as when 20% of total available RAM is used by the node.
   %%
   %% Values greater than 1.0 can be dangerous and should be used carefully.
   %%
   %% One alternative to this is to use durable queues and publish messages
   %% as persistent (delivery mode = 2). With this combination queues will
   %% move messages to disk much more rapidly.
   %%
   %% Another alternative is to configure queues to page all messages (both
   %% persistent and transient) to disk as quickly
   %% as possible, see http://www.rabbitmq.com/lazy-queues.html.
   %%
   %% {vm_memory_high_watermark_paging_ratio, 0.5},

%% Selects Erlang VM memory consumption calculation strategy. Can be `allocated`, `rss` or `legacy` (aliased as `erlang`),
   %% Introduced in 3.6.11. `rss` is the default as of 3.6.12.
   %% See https://github.com/rabbitmq/rabbitmq-server/issues/1223 and rabbitmq/rabbitmq-common#224 for background.
   %% {vm_memory_calculation_strategy, rss},

%% Interval (in milliseconds) at which we perform the check of the memory
   %% levels against the watermarks.
   %%
   %% {memory_monitor_interval, 2500},

%% The total memory available can be calculated from the OS resources
   %% - default option - or provided as a configuration parameter:
   %% {total_memory_available_override_value, "5000MB"},

%% Set disk free limit (in bytes). Once free disk space reaches this
   %% lower bound, a disk alarm will be set - see the documentation
   %% listed above for more details.
   %%
   %% {disk_free_limit, 50000000},
   %%
   %% Or you can set it using memory units (same as in vm_memory_high_watermark)
   %% with RabbitMQ 3.6.0+.
   %% {disk_free_limit, "50MB"},
   %% {disk_free_limit, "50000kB"},
   %% {disk_free_limit, "2GB"},

%% Alternatively, we can set a limit relative to total available RAM.
   %%
   %% Values lower than 1.0 can be dangerous and should be used carefully.
   %% {disk_free_limit, {mem_relative, 2.0}},

%%
   %% Clustering
   %% =====================
   %%

%% Queue master location strategy:
   %%   * <<"min-masters">>
   %%   * <<"client-local">>
   %%   * <<"random">>
   %%
   %% Related doc guide: https://www.rabbitmq.com/ha.html#queue-master-location
   %%
   %% {queue_master_locator, <<"client-local">>},

%% Batch size (number of messages) used during eager queue mirror synchronisation.
   %% Related doc guide: https://www.rabbitmq.com/ha.html#batch-sync. When average message size is relatively large
   %% (say, 10s of kilobytes or greater), reducing this value will decrease peak amount
   %% of RAM used by newly joining nodes that need eager synchronisation.
   %%
   %% {mirroring_sync_batch_size, 4096},

%% Enables flow control between queue mirrors.
   %% Disabling this can be dangerous and is not recommended.
   %% When flow control is disabled, queue masters can outpace mirrors and not allow mirrors to catch up.
   %% Mirrors will end up using increasingly more RAM, eventually triggering a memory alarm.
   %%
   %% {mirroring_flow_control, true},

%% Additional server properties to announce to connecting clients.
   %%
   %% {server_properties, []},

%% How to respond to cluster partitions.
   %% Related doc guide: http://www.rabbitmq.com/partitions.html
   %%
   %% {cluster_partition_handling, ignore},

%% Mirror sync batch size, in messages. Increasing this will speed
   %% up syncing but total batch size in bytes must not exceed 2 GiB.
   %% Available in RabbitMQ 3.6.0 or later.
   %%
   %% {mirroring_sync_batch_size, 4096},

%% Make clustering happen *automatically* at startup - only applied
   %% to nodes that have just been reset or started for the first time.
   %% Related doc guide: http://www.rabbitmq.com/clustering.html#auto-config
   %%
   %% {cluster_nodes, {['rabbit@my.host.com'], disc}},

%% Interval (in milliseconds) at which we send keepalive messages
   %% to other cluster members. Note that this is not the same thing
   %% as net_ticktime; missed keepalive messages will not cause nodes
   %% to be considered down.
   %%
   %% {cluster_keepalive_interval, 10000},

%%
   %% Statistics Collection
   %% =====================
   %%

%% Set (internal) statistics collection granularity.
   %%
   %% {collect_statistics, none},

%% Statistics collection interval (in milliseconds). Increasing
   %% this will reduce the load on management database.
   %%
   %% {collect_statistics_interval, 5000},

%% Enables vhosts tracing.
   %%
   %% {trace_vhosts, []},

%% Explicitly enable/disable HiPE compilation.
   %%
   %% {hipe_compile, false},

%% Number of delegate processes to use for intra-cluster communication.
   %% On a node which is part of cluster, has more than 16 cores and plenty of network bandwidth,
   %% it may make sense to increase this value.
   %%
   %% {delegate_count, 16},

%% Number of times to retry while waiting for internal database tables (Mnesia tables) to sync
   %% from a peer. In deployments where nodes can take a long time to boot, this value
   %% may need increasing.
   %%
   %% {mnesia_table_loading_retry_limit, 10},

%% Amount of time in milliseconds which this node will wait for internal database tables (Mnesia tables) to sync
   %% from a peer. In deployments where nodes can take a long time to boot, this value
   %% may need increasing.
   %%
   %% {mnesia_table_loading_retry_timeout, 30000},

%% Size in bytes below which to embed messages in the queue index.
   %% Related doc guide: http://www.rabbitmq.com/persistence-conf.html
   %%
   %% {queue_index_embed_msgs_below, 4096},

%% Maximum number of queue index entries to keep in journal
   %% Related doc guide: http://www.rabbitmq.com/persistence-conf.html.
   %%
   %% {queue_index_max_journal_entries, 32768},

%% Number of credits that a queue process is given by the message store
   %% By default, a queue process is given 4000 message store credits,
   %% and then 800 for every 800 messages that it processes.
   %%
   %% {msg_store_credit_disc_bound, {4000, 800}},

%% Minimum number of messages with their queue position held in RAM required
   %% to trigger writing their queue position to disk.
   %%
   %% This value MUST be higher than the initial msg_store_credit_disc_bound value,
   %% otherwise paging performance may worsen.
   %%
   %% {msg_store_io_batch_size, 4096},

%% Number of credits that a connection, channel or queue are given.
   %%
   %% By default, every connection, channel or queue is given 400 credits,
   %% and then 200 for every 200 messages that it sends to a peer process.
   %% Increasing these values may help with throughput but also can be dangerous:
   %% high credit flow values are no different from not having flow control at all.
   %%
   %% Related doc guide: https://www.rabbitmq.com/blog/2015/10/06/new-credit-flow-settings-on-rabbitmq-3-5-5/

%% Number of milliseconds before a channel operation times out.
   %%
   %% {channel_operation_timeout, 15000},

%% Number of queue operations required to trigger an explicit garbage collection.
   %% Increasing this value may reduce CPU load and increase peak RAM consumption of queues.
   %%
   %% {queue_explicit_gc_run_operation_threshold, 1000},

%% Number of lazy queue operations required to trigger an explicit garbage collection.
   %% Increasing this value may reduce CPU load and increase peak RAM consumption of lazy queues.

%% Milliseconds to wait between disk monitor retries on failures.
   %%
   %% {disk_monitor_failure_retry_interval, 120000},

%% Whether or not to enable background periodic forced GC runs for all
   %% Erlang processes on the node in "waiting" state.
   %%
   %% Disabling background GC may reduce latency for client operations,
   %% keeping it enabled may reduce median RAM usage by the binary heap
   %% (see https://www.erlang-solutions.com/blog/erlang-garbage-collector.html).

   %% One of
   %%   - false (no logging is performed)
   %%   - true (verbose logging of the logic used by the plugin)
   %%   - network (as true, but additionally logs LDAP network traffic)
   %%
   %% Defaults to false.

%% Pattern to convert the username given through AMQP to a DN before
   %% binding
   %%
   %% {user_dn_pattern, "cn=${username},ou=People,dc=example,dc=com"},

%% Alternatively, you can convert a username to a Distinguished
   %% Name via an LDAP lookup after binding. See the documentation for
