What happened?

Hi,
We are facing an issue in parsing the log field 'sent-request-id'.
The data type defined by ETCD is uint64. But after a certain time, the value of the 'sent-request-id' field exceeds the uInt64 range, and we face an error while parsing such value.
We request you to let us know if ETCD can change the data type of 'sent-request-id' to string in order to handle the above scenario.

Example:
'sent-request-id':12752936093112128921

{'timestamp':'2023-06-07T17:33:12.218Z','level':'warn','caller':'etcdserver/v3_server.go:840','sent-request-id':12752936093112128921,'retry-timeout':'500ms','ts':'2023-06-07T17:33:12.218Z','@Version':'1','msg':'waiting for ReadIndex response took too long, retrying','metadata':{'pod_uid':'5c313bfb-4ec5-46f7-971e-cd4ac8b12767','node_name':'node-1','container_name':'ab','namespace':'ns','pod_name':'abc'}

What did you expect to happen?

We expect the value of 'sent-request-id' to be in the range of uint64, and not exceed the same.

How can we reproduce it (as minimally and precisely as possible)?

Just by performing normal installation and parsing the mentioned JSON field.

Anything else we need to know?

Hi @ankitg-03 - Thanks for raising this question.

I might be missing something but uint64 is the set of all unsigned 64-bit integers (0 to 18446744073709551615). Refer to https://go.dev/ref/spec#Numeric_types.

The example you have provided, 12752936093112128921 is ~5 quintillion less than 18446744073709551615?
