Method Detail

partitionResolver

public BuilderT partitionResolver(java.util.function.Function<ContextT,java.lang.String> contextToPartition)

Add a resolver from context to a partition name. Multiple resolvers may be added and will be processed in order with this first non-null value response used as the partition name. If all resolvers return null then the unknown partition is used

Parameters:

contextToPartition -

Returns:

Chainable builder

partition

public BuilderT partition(java.lang.String name,
                          double percent)

Specify percentage of limit guarantees for a partition. The total sum of partitions must add up to 100%

Parameters:

name -

percent -

Returns:

Chainable builder

partitionRejectDelay

public BuilderT partitionRejectDelay(java.lang.String name,
                                     long duration,
                                     java.util.concurrent.TimeUnit units)

Delay introduced in the form of a sleep to slow down the caller from the server side. Because this can hold off RPC threads it is not recommended to set a delay when using a direct executor in an event loop. Also, a max of 100 threads may be delayed before immediately returning

Parameters:

name -

duration -

units -

Returns:

Chainable builder

maxDelayedThreads

public BuilderT maxDelayedThreads(int maxDelayedThreads)

Set the maximum number of threads that can be held up or delayed when rejecting excessive traffic for a partition. The default value is 100.

Parameters:

maxDelayedThreads -

Returns:

Chainable builder

hasPartitions

protected boolean hasPartitions()
