Providers for LoggingEvents - Sequence

[alvhartanto]

Hi, does sequence option have reset feature for every new trace id (e.g. spring sleuth trace id)?

If not, does sequence option have maximum values?

Thank you in advance

No, the log sequence id is unrelated to trace id / span id.

The trace id / span id are usually put into the MDC, and included in the json output along with other values in the MDC via the mdc provider.

does sequence option have maximum values?

The maximum sequence id is Long.MAX_VALUE, which is 2^63 - 1, which is 9,223,372,036,854,775,807

Hi @philsttr , thank you for the prompt answers, I got several questions again regarding sequence if you don't mind

1. So, the only way to reset the sequence is restarting the service itself?
2. What happened when sequence value reached Long.MAX_VALUE? Does it make the application crash?

Thank you in advance :)

1. yes
2. It will roll over to Long.MIN_VALUE, but keep in mind that if the application logs a message every micro second, it will take close to 300 thousand years before it rolls over
