8 Ways to Optimize AWS Glue Jobs in a Nutshell

Image
  Improving the performance of AWS Glue jobs involves several strategies that target different aspects of the ETL (Extract, Transform, Load) process. Here are some key practices. 1. Optimize Job Scripts Partitioning : Ensure your data is properly partitioned. Partitioning divides your data into manageable chunks, allowing parallel processing and reducing the amount of data scanned. Filtering : Apply pushdown predicates to filter data early in the ETL process, reducing the amount of data processed downstream. Compression : Use compressed file formats (e.g., Parquet, ORC) for your data sources and sinks. These formats not only reduce storage costs but also improve I/O performance. Optimize Transformations : Minimize the number of transformations and actions in your script. Combine transformations where possible and use DataFrame APIs which are optimized for performance. 2. Use Appropriate Data Formats Parquet and ORC : These columnar formats are efficient for storage and querying, signif

2 Best Ways to Concatenate Strings in Python

Concatenation of strings in Python is possible by using the plus and join method. You can also do it in other ways. But in my point of view, these two are the best methods.

What are Strings?


A string represents in quotes. Let us see the data. It can have all kinds of data. A lot you can do by manipulating strings. Concatenation is one.


Example for strings 

Stringa='Uncle'
Stringb='is'
Stringc='Married'


Above example, you can see three strings. To make all these strings into a single, you need the concept of concatenation.

What is string concatenation?


String concatenation is a frequent activity in data science. Knowing this concept is helpful in your project and interviews as well.

You can do it using the two best methods. One is you can use plus operator. For the other one, you can use the join method.


#1: Using the plus operator


Stringa='Uncle'
Stringb='is'
Stringc='Married'
print(Stringa + ' ' + Stringb + ' ' + Stringc)


Result:

Uncle is Married


#2: Using the join method with separator.


Stringa='Uncle'
Stringb='is'
Stringc='Married'
a=' '.join([Stringa, Stringb, Stringc])
print(a)


Result:

Uncle is Married
