Vector search FAQs

This topic describes some common issues that may occur when using vector search, as well as their causes and solutions.

Must all rows in a vector column have the same data dimensionality?

Yes. A data dimensionality must be specified when a vector column is defined, and the dimensionality must be verified when vector data is written into the column.

What is the maximum number of rows of vector data that can be written?

Unlimited. It depends on the database memory resources.

How do I create an index on a vector with more than 4096 dimensions?

You need to compress the data to within 4096 dimensions before creating an index.
