CMQ provides finance-grade message transmission with high reliability and high data persistence while ensuring strong data consistency.
CKafka is suitable for scenarios that require higher throughput and lower reliability (such as log aggregation). In addition, CKafka is compatible with existing Kafka users, enabling migration at zero cost with full instance exclusivity.
Currently, CKafka is fully compatible with open-source Kafka API 0.9, 0.10, 1.1, and 2.4, allowing users to migrate data to the cloud at zero cost.
The current CKafka is based on Apache Kafka 0.10, 1.1, and 2.4. We recommend using an SDK for production and consumption according to the Apache Kafka's version.
CKafka does not expose ZooKeeper or its address.
Currently, CKafka transfers data over the private network by default. As public network access runs the risk of issues such as delay and network environment security, we do not recommend long-term use of public network transfer.
If you have a temporary need for public network transfer, please contact your Tencent Cloud account manager for evaluation and assistance.
Currently, CKafka supports open-source Snappy and LZ4 message compression formats. Because gzip compression consumes more CPU resources, it is currently not supported.
We recommend disabling message compression when testing.
Configuration Method: in the configuration file of the producer, set the
compression.type parameter to
lz4. The default value is
none, indicating that the feature is disabled.
CKafka is compatible with open-source Kafka 0.9, 0.10, 1.1, and 2.4. You can connect to the message center via a Kafka client and deploy codes to Tencent Cloud services to produce or consume messages.
Different instance specifications have different restrictions on peak throughput, disk capacity, number of topics at the instance level, and number of partitions at the instance level. For more information, see Billing Overview.
CKafka guarantees security by using following features:
