Hello,

with TimescaleDB it is good idea to Override item history period:

 

For numeric history it's OK to delete after few weeks, because data stays in trends for years.

But with strings like software versions or serial numbers it makes more sense using "discards when unchanged" and keep at least few months.

 

Unfortunately both are set by same override.

I propose a separate override value for trends-enabled-type item histories and different override value for trends-less-type item histories.
