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

Top features of HPCC -High performance Computing Cluster

Hadoop Jobs
[Hadoop Jobs]
HPCC (High-Performance Computing Cluster) was elaborated and executed by LexisNexis Risk Solutions. The creation of this data processing program started in 1999 and applications remained in manufacture by belated 2000. 

The HPCC style as well uses product arrays of equipment operating the Linux Operating System. Custom configuration code and Middleware parts remained elaborated and layered on the center Linux Operating System to supply the implementation ecosystem and dispersed filesystem aid needed for data-intensive data processing. LexisNexis as well executed a spic-and-span high-level lingo for data-intensive data processing.
  • The ECL (data-centric program design language)|ECL program design lingo is a high-level, declarative, data-centric, Implicit parallelism|implicitly collateral lingo that permits the software coder to determine what the information handling effect ought to be and the dataflows and transformations that are required to attain the effect. 
  • The ECL lingo contains encompassing abilities for information description, filtrating, information administration, and information alteration, and delivers an encompassing set of integrated purposes to handle on records in datasets that may contain user-defined alteration purposes. ECL programmes are assembled in to enhanced C++ origin code, that is afterward assembled in to workable code and dispersed to the nodes of a handling array.
To address either lot and on the web facets data-intensive data processing applications, HPCC contains 2 clearly different array surroundings, every one of that may be enhanced separately for its collateral information handling aim. The Thor program is a array whose aim is to be a information refinery for handling of huge masses of rare information for applications such like information cleansing and sanitation, withdraw, change, fill (ETL), record connecting and being resolve, extensive Ad Hoc examination of information, and formation of Keyed information and guides to aid high-performance organized requests and information storage applications. 

A Thor configuration is alike in its equipment arrangement, purpose, implementation ecosystem, filesystem, and abilities to the Hadoop MapReduce program, however delivers developed execution in equal arrangements. The Roxie program delivers an on the web high-performance organized request and examination configuration either information storage providing the collateral information access handling conditions of on the web applications via Web facilities interactions helping 1000s of concurrent requests and consumers with sub-second reply periods. 

A Roxie configuration is alike in its purpose and abilities to Hadoop with HBase and Apache Hive|Hive abilities appended, however delivers an enhanced implementation ecosystem and filesystem for high-performance on the web handling. Both Thor and Roxie setups use the similar ECL program design lingo for executing applications, expanding software coder efficiency.
