Python AWS 库 Boto3:kinesis.get_records(shard_iterator)
我无法处理从 boto3 库运动函数 get_records(ShardIterator=shard_iterator,Limit=123) 获取的记录。
我得到的数据看起来像 b '\xe0\x01\x00\xea\xee\x01\xe4\x81\x83\xde\x01\xdf\x87\xbe\x01\xdb\x8dqldbStreamArn\x8arecordType\x87payload\x8cblockAddress\x88strandId\x8aseequenceNo\x8dtransactionId\ x8e\x8eblockTimestamp\x89blockHash\x8bentriesHash\x8e\x91previousBlockHash\x8e\x8fentriesHashList\x8e\x8ftransactionInfo\x8astatements\x89statement\x89startTime\x8e\x8f statementsDigest\xde\x03\xe5\x8a\x8e\xcdarn:aws:qldb:ap-southeast-1:417160253190:stre上午/钱包/5vHof6xwrwr2hzc2tw6HYw\x8b\x8dBLOCK_SUMMARY\x8c\xde\x03\x82\x8d\xde\x9d\x8 e\x8e\x96G8ijftVQqbp6Azm3UptzGq\x8f"\x1b\xa9\x90\x8e\x96EVaGqOlkbkwB9mBuOkdKTI\x91k\ x80\x0f\xe6\x83\x87\x89\x8c\x96\xc3\x01\r\x92\xae\xa0\x99R\xbe\xcba\xc5\xbc\xef\xcdd \xc2am\xc0\xb8Ro\xf3\x88\xa3tz\x94o\x8a\x98\x15`h@\x18\x93\xae\xa0\xee\xf2\x9d\xf5@*e\x13\x82 \xd5\xee\x88\x018\xc2\xc4\xa3\x15\xc9\x85 \xe7\xea\xbf\xb0\x1eU\xf0\x124w\x94\xae\xa0\x94\x1b@\x11V\x90S\xe7\x1b\x8ei\xf7\xc5\xba}\x0cJ\x10\xe9Rx\x9 1q\x14\x8c\x02`\x0b\xdc+\x13\xcb\x95\xbe\xc5\xae\xa0u/\xc6M\xb4\x97\xf8\xa9\xa4&1\xb7*\xb2\x17\x1dB \xc 6c\x92\x9d\xcc\xecP2\r\xcf\xfa\xf8\x1f\x0f\x85\xa0\xae\xa0\xe9}\x7f\xc0>\xdf\xf5-\x8f\x9d\xa6kg\xa8 \xf0 \xbfHybS,\x83\xbc\x8f\xbe\x1bG\x07\xd1\xbf{:\x96\xde\x01\x87\x97\xbe\x01\x83\xde\x01\x80\x98\x8e\xcdSELECT VALUE 名称来自 information_schema.user_tables WHERE status = \'活动\'\x99k\x80\x0f\xe6\x83\x87\x89\x8c\x96\xc3\x00\xdd\x9a\xae\xa0\xaf\xbd\xae\x00 \xbf\xb8ds\xb3\xf4\xa1\xd3tL\x9f\xe8R=\x12\xe2\xc5*\xbcwx\x98\xb1\xa37(\x1c\xcb'

请帮助我处理此类数据。

Please help me out to process these kind of data.

遵循 Kinesis.Client< /a> 文档,您必须提供一个分片迭代器,并且在迭代可用记录之后可以继续使用下一个分片迭代器。
以下是自某个时间点以来记录迭代的基本示例:
查看 文档了解更多详细信息。
Following the Kinesis.Client documentation you have to provide a shard iterator and after iteration of the available records can proceed with next shard iterator.
Here is a basic example of iteration of the records since some point in time:
Check out the documentation for more details.
您需要执行如下操作:
You need to do something like the following:
