In order toiterate over columns,we need to create a list of DataFrame columns and iterating through that list to pull out the DataFrame columns. retrieve the fifth element of the column. # Iterating over columns
strings, floating-point numbers, Python objects, etc.). Series stores data in sequential order. It is one-column information. Series can take any type of data, but it should be consistent throughout the series (all values in a series should have the same type). You can create a series ...
Data Tiering is an extremely powerful approach to optimize your data in the most cost-effective manner. With the SAP HANA Native Storage Extension, we are providing the capability to dynamically off-load data from SAP HANA’s in-memory storage to provide capacity for more frequently accesse...

Ibis is a Python dataframe library that decouples the API from the execution engine. Most Python dataframes (pandas, Polars, PySpark, Snowpark, etc.) tightly couple these -- resulting in slight differences in API and a lot of overhead in converting between them. Ibis instead uses an ...
