kafka offset 设置

http://stackoverflow.com/questions/36579815/kafka-python-how-do-i-commit-a-partition
from kafka import KafkaConsumer
from kafka import TopicPartition
from kafka.structs import OffsetAndMetadata
...
topic = ‘your_topic‘
partition = 0
tp = TopicPartition(topic,partition)
kafkaConsumer = KafkaConsumer(config here...)
kafkaConsumer.assign([tp])
offset = 15394125
kafkaConsumer.commit({
    tp: OffsetAndMetadata(offset, None)
})

meta = consumer.partitions_for_topic(topic)
options = {}
options[partition] = OffsetAndMetadata(message.offset, meta)
consumer.commit(options)

如果consumer.commit()不可以，可以使用seek()，使用seek()，如果有多个partition，需要为每个partition都手动进行consumer assign.

topic_partition = TopicPartition("TOPIC_TEST", 1)
# 格式为topic, partition, 1表示partition 1.
consumer.assign([topic_partition])

consumer.seek(topic_partition, 1660000)
同样的代码，有些用commit可以，有些不可以，用seek()就可以。
