oldPoliciesCompatible

public static OffloadPoliciesImpl oldPoliciesCompatible(OffloadPoliciesImpl nsLevelPolicies,
 Policies policies)

This method is used to make a compatible with old policies.

The filed Policies.offload_threshold is primitive, so it can't be known whether it had been set. In the old logic, if the field value is -1, it could be thought that the field had not been set.

参数:

nsLevelPolicies - namespace level offload policies

policies - namespace policies

返回:

offload policies

mergeConfiguration

public static OffloadPoliciesImpl mergeConfiguration(OffloadPoliciesImpl topicLevelPolicies,
 OffloadPoliciesImpl nsLevelPolicies,
 Properties brokerProperties)

Merge different level offload policies.

policies level priority: topic > namespace > broker

参数:

topicLevelPolicies - topic level offload policies

nsLevelPolicies - namespace level offload policies

brokerProperties - broker level offload configuration

返回:

offload policies
