only a single field is supported as a partition key, which can be a primary key or not, a table can only have one partition key, each record will be hashed and mapped to diffrent partition, unsupport field with type: BOOL、FLOAT、DOUBLE、FLOAT_VECTOR

auto_increment: bool

is autoincreament, only applicable to primary key fields of type UINT64

not_null: bool

primary key field, partition key field, secondary index key field and vector field cannot be nullable

dimension: Option<u32>

vector dimension. This parameter needs to be specified only when the data type is FLOAT_VECTOR.
