import numpy as np
df = pd.DataFrame({'a':[1,2,3,4]})
df.head()

> 1 2
> 2 3
> 3 4
conditions = [(df['a'] <=2...
Are there any plans / capabilities in place or approaches people are using for writing (logging) records failing constraint requirements to separate tables when using Delta Live Tables? Also, are there any plans / capabilities in place or approaches ...
According to the language reference documentation, I do not believe quarantining records is possible right now out of the box. But there are a few workarounds under the current functionality. Create a second table with the inverse of the expectations...
If you have familiarity with Scala you can use Tika. Tika is a wrapper around PDFBox. In case you want to use it in Databricks I suggest you to go through this blog and Git repo. For python based codes you may want to use PyPDF2 as a pandas UDF in S...

Replacing max_iter with n_iter resolves the error. Thnx!

I am able to load data for single container by hard coding, but not able to load from multiple containers. I used for loop, but data frame is loading only last container's last folder record only.Here one more issue is I have to flatten data, when I ...
for sure function (def) should be declared outside loop, move it after importing libraries,logic is a bit complicated you need to debug it using display(Flatten_df2) (or .show()) and validating json after each iteration (using break or sleep etc.)
Hi as it is transaction tables (there are history commits and snapshot). I would not store there images or videos as it can be saved few times and you will have high storage costs, it can also be slow when data is big.I would definitely store images,...

Modern Spark operates by a design choice to separate storage and compute. So saving a csv to the river's local disk doesn't make sense for a few reasons:the worker nodes don't have access to the driver's disk. They would need to send the data over to...
