Method Detail

partitionByLookup

public BuilderT partitionByLookup(java.util.function.Function<ContextT,java.lang.String> contextToGroup,
                                  java.util.function.Consumer<LookupPartitionStrategy.Builder<ContextT>> configurer)

Configure the strategy for partitioning the limit.

Parameters:

contextToGroup - Mapper from the context to a name group associated with a percentage of the limit

configurer - Function through which the value set support by the func may be assigned a percentage of the limit

Returns:
