KAFKA VS GOOGLE CLOUD PUBSUB: 2020 COMPARISON

Feature Confluent Cloud Kafka Google Cloud Pubsub Notes Data Retention Set retention per topic in Confluent Cloud, including unlimited retention with log compaction. Retains unacknowledged messages in persistent storage for 7 days from the moment of publication. There is no limit on the number of retained messages. Have to write custom subscriber/publisher to save beyond 7 days [L] + ongoing BAU [S] Replay A consumer request an “offset”, however the retention period is dictated by the broker config “Snapshots” can be created for later replay by these are limited to 7 days as per retention policy. As per above, a custom subscriber/publisher to save/replay message. [L] + ongoing BAU [S] Message Ordering Yes, within a partition, In general, messages are written to the broker in the same order that they are received by the producer client. No, Pub/Sub provides a highly-available, scalable message delivery service. The tradeoff for having these properties is that the order in which messages are received by subscribers is not guaranteed. While the lack of ordering may sound burdensome, there are very few use cases that actually require strict ordering. Delivery Semantics Exactly-once delivery semantics At-least-once, exactly once possible with dataflow Latency Advertised at being able to “Achieve sub 30 ms latency at scale”, no mention of this in SLA. Pub/Sub does not guarantee message delivery latency Uptime “Service Level” Monthly Uptime Percentage of at least 99.95%.Is this 99.95% of GCP’s 99.95%? “Service Level Objective” Monthly Uptime Percentage to Customer of at least 99.95% Both offer credits to account if not met but this is unlikely to be suitable for an enterprise org Schema Registry Yes for Avro schemas and very new (GA August 2019) No, Data Catalog is in beta and could be used to build one [XL] IAM / ACL “Preview” for Role/SAML, ACLs You are provided auth keys that you need to store/share/rotate. These could be stored in Cloud KMS, however, this would need to be automated [XL] + ongoing BAU [M] Standard Google IAM Encryption Yes in transit and at rest with NO payload encryption. Clients are responsible for writing custom encryption/decryption connecting to (e.g) Cloud KMS.
