# if supervisor.slots.ports is null, 
# the port list will be generated by cpu cores and system memory size 
# for example, 
# there are cpu_num = system_physical_cpu_num/supervisor.slots.port.cpu.weight
# there are mem_num = system_physical_memory_size/(worker.memory.size * supervisor.slots.port.mem.weight) 
# The final port number is min(cpu_num, mem_num)

# enable supervisor use cgroup to make resource isolation
# Before enable it, you should make sure:
# 	1. Linux version (>= 2.6.18)
# 	2. Have installed cgroup (check the file's existence:/proc/cgroups)
#	3. You should start your supervisor on root
# You can get more about cgroup:

### Netty will send multiple messages in one batch  
### Setting true will improve throughput, but more latency
# storm.messaging.netty.transfer.async.batch: true

### if this setting  is true, it will use disruptor as internal queue, which size is limited
### otherwise, it will use LinkedBlockingDeque as internal queue , which size is unlimited
### generally when this setting is true, the topology will be more stable,
### but when there is a data loop flow, for example A -> B -> C -> A
### and the data flow occur blocking, please set this as false
# topology.buffer.size.limited: true
 
### default worker memory size, unit is byte
# worker.memory.size: 2147483648

# Metrics Monitor
# topology.performance.metrics: it is the switch flag for performance 
# purpose. When it is disabled, the data of timer and histogram metrics 
# will not be collected.
# topology.alimonitor.metrics.post: If it is disable, metrics data
# will only be printed to log. If it is enabled, the metrics data will be
# posted to alimonitor besides printing to log.
# topology.performance.metrics: true
# topology.alimonitor.metrics.post: false

# Following is an example of multicluster UI configuration
