Subject Re: Kafka data log timestamp
Date Thu, 10 Jan 2019 10:18:38 GMT
You can use kafkacat to examine the timestamp (and other metadata). Here's
an example of calling it, and two sample output records:

$ kafkacat -b localhost:9092 -t mysql_users -C -c2 -f '\nKey (%K bytes):
%k\t\nValue (%S bytes): %s\nTimestamp: %T\tPartition: %p\tOffset: %o\n--\n'

Key (1 bytes): 1
Value (79 bytes):
{"uid":1,"name":"Cliff","locale":"en_US","address_city":"St
Louis","elite":"P"}
Timestamp: 1520618381093        Partition: 0    Offset: 0
--

Key (1 bytes): 2
Value (79 bytes):
{"uid":2,"name":"Nick","locale":"en_US","address_city":"Palo
Alto","elite":"G"}
Timestamp: 1520618381093        Partition: 0    Offset: 1
