Thx @haoch @RalphSu. I thought we set async for kafka producer and what we
need to change is using callback rather than future wait, it is wrong, thanks
for pointing out.
I have updated the code to add kafka_client_config (list of name/value map)
to specify kafka producer configurations.
By default, I only set producer.type=async.
For batch.num.messages, queue.buffering.max.ms and
queue.buffering.max.messages, I think we can use kafka producer default
values.
The only difference for default value is batch.num.messages, it is 200 if
not specified. Could u please share with us what is your reason to set it to
3000?
the kafka producer properties could be defined in publish properties as
follows:
{
"name": "***",
"properties" : {
"kafka_broker": "***",
"topics": "***",
"kafka_client_config" : [
{
"name" : "request.requrie.acks",
"value": 1
},
{
"name" : "producer.type",
"value": "async"
},
...
]
}
}
