Inconsistent Vector Size When Writing Historical Data

Forum / Questions & Answers

Hey Guys,

I'm fairly new to Canary, and I'm struggling to understand how Vectors work. The only documentation I found says the Vector size should be based on data type. However, I am using an Ignition script (system.tag.storeTagHistory) to push historical data into Canary, and it gives me these wildly varying Vector sizes, despite being the same data type.

Any idea what causes this?

Thanks,

Christian

    Hi christian. pionke ,

    The vector size is really irrelevant to the end user, but the fact that you are inserting historical data into the archive is going to force these vector sizes to change size and possibly even split as there is a limit as to how much data we store in a single vector.
