TDEngineTarget.The possible timestamp precisions in TDEngine are:
See:
https://docs.tdengine.com/tdengine-reference/sql-manual/data-types/#timestamp
https://docs.tdengine.com/tdengine-reference/sql-manual/manage-databases/#create-database
We previously supported only ms - TDEngine's default.
The precision is set for the whole database. It is stored in the metadata database:
https://docs.tdengine.com/tdengine-reference/sql-manual/metadata/#ins_databases
Note: the ns precision is not natural in Python, so I do not expect it to be used.
I tested it while running an MLRun system test, and it works.
