Kafka data log timestamp

[Parth Gandhi <pa...@excellenceinfonet.com>]

Hi,

Does kafka record the timestamp of the incoming message in its data log? I
checked one of the partition log and I can see the message without any
timestamp. Also there are few special characters in the message log. IS
that normal?

Here is a sample log: pastebin.com/hStyCW13

Thanks,

Thatns Robin. Can you send reference to it? Also can it be used for log
file stored locally (not in DB)?

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
