Comparing RabbitMQ AMQP-0-9-1 with Open-Source RabbitMQ
DMS for RabbitMQ of the AMQP-0-9-1 version is message-oriented middleware using the highly available distributed architecture. This version is compatible with open-source RabbitMQ clients. DMS for RabbitMQ addresses message stacking, split-brain, and other stability issues in open-source RabbitMQ. In addition, DMS for RabbitMQ features high concurrency, distributed deployment, and flexible scaling.
The following section describes the comparison by function, stability, exchange, and queue.
Functions
Function |
AMQP-0-9-1 |
Open Source |
---|---|---|
Client SDKs |
Open-source SDKs of all languages and versions are supported. |
Open-source SDKs are supported. |
Scheduled messages |
Can be scheduled at any time, precise in seconds, and stacked massively. |
By plug-ins or message time-to-live (TTL). |
Transactional messages |
Not supported. |
Supported. |
Ordered messages |
Not supported. |
Supported. |
Message priority |
Supported. |
Supported. |
Message retry mechanism |
Supported. Messages will be re-delivered if no response is received within a specified period of consumption. Retry intervals: 1 minute. Maximum of retries: 16. Messages will be discarded or sent to dead letter exchanges later. |
Not supported. |
Monitoring metrics |
Rich metrics of virtual host, exchange, and queue. |
The following two schemes are supported:
|
Message tracing |
A whole message lifecycle can be traced and displayed on a white screen. Messages can be indexed by queue, message ID, and message processing duration. |
Message traces are stored by text in the log file on servers. Querying or locating may be inefficient. |
Stability
Function |
AMQP-0-9-1 |
Open Source |
---|---|---|
Message stacking |
Massive messages are allowed to be stacked. High performance is not affected. |
Stacked messages easily cause memory-induced breakdown. |
Scalability |
An architecture of distributed clusters without masters supports rapid scale-out of clusters. |
Expansions and reductions by changing machine specifications. |
Service availability |
99.95% achieved by distributed clusters across availability zones (AZs). |
Developed by Erlang. Experiential O&M. Stability issues remain unresolved. |
Data reliability |
Data in triple replicas, which does not affect the TPS performance. |
Increasing replicas deteriorates TPS performance. |
Inspection |
Dead locks or breakdowns can be automatically detected and rectified. |
None. |
Exchange
Function |
AMQP-0-9-1 |
Open Source |
---|---|---|
Exchange type |
Direct, fanout, headers, topic, x-delayed-message and x-consistent-hash. |
Direct, fanout, headers, topic, x-delayed-message and x-consistent-hash. |
Persistence |
Enabled by default. |
Can be configured. |
Automatic deletion |
Supported. |
Supported. |
Internal |
Not supported. |
Supported. |
Alternate exchange |
Not supported. |
Supported. |
Consistent hash exchange |
Supported. |
Supported. |
Queue
Function |
AMQP-0-9-1 |
Open Source |
---|---|---|
Queue type |
Distributed high availability clusters by default. |
The following types can be configured:
|
Node |
O&M-free by default. |
Needs to be configured. |
Persistence |
Enabled by default. |
Persistence or non-persistence is supported. |
Max length |
By default, massive messages can be stacked. |
Needs to be configured to avoid system breakdowns due to message stack-induced memory issues. |
Max length bytes |
By default, massive messages can be stacked. |
Needs to be configured to avoid system breakdowns due to message stack-induced memory issues. |
Max in memory length |
By default, massive messages can be stacked. |
Needs to be configured to avoid system breakdowns due to message stack-induced memory issues. |
Max in memory bytes |
By default, massive messages can be stacked. |
Needs to be configured to avoid system breakdowns due to message stack-induced memory issues. |
Delivery limit |
Fixed, 16 by default. |
Needs to be configured. |
Dead letter exchange |
Supported. |
Supported. |
Dead letter routing key |
Supported. |
Supported. |
Single active consumer |
Not supported. |
Supported. |
