Examples with UpdateMetadataPartitionState org.apache.kafka.common.message.UpdateMetadataRequestData.UpdateMetadataPartitionState used on opensource projects

Example 1 with UpdateMetadataPartitionState

use of org.apache.kafka.common.message.UpdateMetadataRequestData.UpdateMetadataPartitionState in project kafka by apache.

the class UpdateMetadataRequestTest method testTopicPartitionGroupingSizeReduction.

Example 2 with UpdateMetadataPartitionState

use of org.apache.kafka.common.message.UpdateMetadataRequestData.UpdateMetadataPartitionState in project kafka by apache.

the class UpdateMetadataRequestTest method testVersionLogic.

/**
 * Verifies the logic we have in UpdateMetadataRequest to present a unified interface across the various versions
 * works correctly. For example, `UpdateMetadataPartitionState.topicName` is not serialiazed/deserialized in
 * recent versions, but we set it manually so that we can always present the ungrouped partition states
 * independently of the version.
