This topic describes the general issues that may occur when you use vector search, as well as their causes and solutions.
Which mode supports vector search?
Vector search is supported only in the MySQL mode of OceanBase Database.
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.
How many rows of vector data can be written at most?
That depends on the memory resources of the tenant.
How do I create an index on a vector column with more than 2,000 dimensions?
You must first reduce the dimensionality of the column to 2000 or lower.
Does OceanBase Database provide built-in embedding methods and modeling algorithms?
Not at present. We are planning to provide built-in embedding methods and modeling algorithms in later versions of OceanBase Database.
