History Service data granularity

Camunda 7 Topics Discussion & Questions
1

Hi,

I’m using the historyService.createHistoricProcessInstanceQuery call to get historic events.
However, I’m only able to get up to seconds granularity, not milliseconds. Is seconds the most I can get?
It would be nice to get milliseconds, for many reasons.

Thanks,
Galen

Hi Philipp,

We are using Camunda 7.7.0, and MySQL 5.5.40.

Thanks,

Hi Galen,

it’s because of the MySQL database. Since version 5.6.4, MySQL also supports milliseconds.
Please see the details at CAM-5183.

Best regards,
Philipp

Thanks! We can confirm we do see milliseconds in later versions of the database.
