Does vaex data frame support data generation?

i have a dataset with schema,

Now i would like to generate the data from 28,70,764 to some 3,28,70,764 i.e generating around 30 Million rows so as in pandas we can use the below method.

val = 2870764
df3['POLICY_ID'] = range(val ,val+30000000) 

but as it is huge data pandas can't generate, so is there any approach to solve this problem by doing it in Vaex.

But Vaex throws me an error

ValueError: range(2870764, 5870764) is not of string or Expression type, 
but <class 'range'>

Could anyone suggest whether can we do in this way in Vaex?

Yes, vaex has a function called vrange that does exactly what you're looking for, with no memory usage.

Example:

import vaex

df = vaex.example()
df

Here is a dataframe with 330,000 rows (using the example dataset at the time of writing). We can generate a new column, POLICY_ID using vaex.vrange

df["POLICY_ID"] = vaex.vrange(0, len(df))
