8 Ways to Optimize AWS Glue Jobs in a Nutshell

-

  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

How to Understand Pickling and Unpickling in Python

Here are the Python pickling and unpickling best examples and the differences between these two. These you can use to serialize and deserialize the python data structures. The concept of writing the total state of an object to the file is called  pickling,  and to read a Total Object from the file is called  unpickling. Pickle and Unpickle The process of writing the state of an object to the file (converting a class object into a byte stream) and storing it in the file is called pickling. It is also called object serialization . The process of reading the state of an object from the file ( converting a byte stream back into a class object) is called unpickling.  It is an inverse operation of pickling. It is also called object deserialization .  The pickling and unpickling can implement by using a pickling module since binary files support byte streams. Pickling and unpickling should be possible using binary files. Data types you can pickle Integers Booleans Complex numbers Floats Nor
