What does Atlan crawl from Redpanda Kafka?
Atlan crawls and maps the following assets and properties from Redpanda Kafka.
Once you've crawled Redpanda Kafka, you can use connector-specific filters for quick asset discovery. The following filters are currently supported for these assets:
- Topics - Message count, size (MB), partition count, and cleanup policy filters
- Consumer groups - Member count and topic name filters
Topics
Atlan maps topics from Redpanda Kafka to its KafkaTopic asset type.
| Source property | Atlan property |
|---|---|
| Topic | name |
| PartitionCount | kafkaTopicPartitionsCount |
| ReplicationFactor | kafkaTopicReplicationFactor |
| segment.byte | kafkaTopicSegmentBytes |
| compression.type | kafkaTopicCompressionType |
| cleanup.policy | kafkaLogTopicCleanupPolicy |
| isInternal | kafkaTopicIsInternal |
| sizeInBytes | kafkaTopicSizeInBytes |
| recordCount | kafkaTopicRecordCount |
| retention.ms | kafkaTopicRetentionTimeInMs |
Consumer groups
Atlan maps consumer groups from Redpanda Kafka to its KafkaConsumerGroup asset type.
Did you know?
Consumer groups are most likely to show up only in streaming scenarios. This is because if a topic is not being consumed actively, Redpanda Kafka will purge the consumer group. So, if a consumer group is inactive while the workflow runs in Atlan, it will not be cataloged as an asset.
| Source property | Atlan property |
|---|---|
| GROUP | name |
| memberCount | kafkaConsumerGroupMemberCount |
| ReplicationFactor | kafkaTopicReplicationFactor |
| topic_names | kafkaTopicNames |
| TOPIC | kafkaConsumerGroupTopicConsumptionProperties.topicName |
| PARTITION | kafkaConsumerGroupTopicConsumptionProperties.topicPartition |
| LAG | kafkaConsumerGroupTopicConsumptionProperties.topicLag |
| CURRENT-OFFSET | kafkaConsumerGroupTopicConsumptionProperties.topicCurrentOffset |
