Google Cloud offers a comprehensive data and machine learning workflow that specifies the functions to be performed at each step. It offers storage options, creates machine learning models with a particular focus on their life cycle, and covers the entire data and machine learning processes.

Using native cloud based tools helps a lot with ETL process. Like AWS Glue which is native to aws and using pyspark flavor we can ETL any type of data format to any format or data stores.

I'm exploring SQL Server Integration Services (SSIS) as a solution for data loading and transformation needs. SSIS is indeed a powerful and flexible ETL (Extract, Transform, Load) tool provided by Microsoft as part of the SQL Server suite. It's facilitate the integration of data from various sources into SQL Server or other data warehouses, along with the capability to transform and clean the data during the process. but for the end user I discover also an opensource solution call it knime a powerfull tool for both data engineer and data scientiste

A must have experience and skillset for Teams leveraging big data for Data Science and Analytics in cloud. All major Cloud providers offer services that enable these frameworks easily. Databricks and AWS EMR are popular ones.

When it comes to handling large volumes of data, we have options like Apache Spark, Dask, and Ray, which are powerful frameworks for distributed computing. These tools allow us to process, analyze massive amounts of data in parallel, offering flexibility, scalability. However they do require more technical expertise and infrastructure management compared to cloud-based solutions. It's essential to weigh the benefits of these frameworks against the resources and skills available within your organization. While they provide greater control, they also demand a higher level of configuration and coding skills. Ultimately, the choice between these frameworks and cloud-based ETL services depends on the specific needs and capabilities of your team.

Open-source distributed computing engines like Apache Spark, Flink, and Beam empower large-scale parallel data processing across clusters of machines. Auto-scaling of clusters adapts to workloads seamlessly. These frameworks also offer rich APIs and libraries for data pipelines, streaming analytics, ML, graph processing - all accessible via popular languages like Python and Java. However, the flexibility comes at the cost of provisioning, configuring and managing the underlying infrastructure

Distributed computing simply means the use of multiple computers to process data in parallel which is the opposite of using a simple computer to process data sequentially which was pretty much the traditional method of computing many years ago. Distributed computing is crucial for processing big data because it gives room for the job to done in an efficient and effective manner. It achieves this by dividing large data sets into smaller chunks for easier processing across multiple nodes thereby speeding up the processing speed and creating room for scalability.

A partir do advento do Big Data, iniciando com Hadoop e seus sucessores Data Lakes em nuvem, se fez necessário o uso de estruturas de computa??o distribuída como o Spark, Flink, Beam, Storm, Kafka, além do próprio MapReduce para viabilizar o processamento e a análise de dados em grande escala. Essas ferramentas, além de trazer um alto poder de processamento, trouxeram também uma alta flexibilidade quanto às linguagens de programa??o, podendo-se normalmente utilizar Python, Java, Scala ou mesmo o tradicional SQL. Essas s?o as principais ferramentas utilizadas quando se fala em engenharia de dados e a sua escolha deve ser pensada levando-se em considera??o a arquitetura de dados existente e a necessidade de negócio a ser resolvida.

Dependencies between jobs, triggers, retries, etc. can be configured to handle failures. They also equip users with graphical monitoring, logging, and alerting capabilities. Integrations exist for both cloud-based ETL services as well as for execution frameworks that perform the actual extract, load and transform

SQL based ETL tools like SSIS, snowflake, Bigquery are some example which are being used for data processing. These tools are user friendly and person with knowledge of SQL can easily adapt and leavrage these.

The smooth integration of SQL-based ETL solutions with well-known data lakes and warehouses, including BigQuery, Snowflake, Redshift, and others, is one of their main benefits. Through this interface, customers can take use of these platforms' strength and scalability for effective data processing, storing, and analysis. Furthermore, data validation, testing, and documentation functions are frequently included in SQL-based ETL systems, which can assist guarantee the accuracy and dependability of the converted data.

SSIS is one of the most powerful tool for ETL.It has rich features to handle structured data. Easily manageable and easy to use. With the help of SSIS wizard, easily perform the data transformation and export in all the formats.

I believe SQL based ETL tools are the most user friendly ones. A person without a technical background can start using it with minimum training.

In my experience SQL (Big query) does wonders in ETL processes, since it handles large volumes of data and responding to queries in seconds. There are other SQL tools like PostgreSQL, SQL Server, Oracle, or non-relational databases like MongoDB or data from APIs. SQL queries are used to extract specific datasets or tables from these sources.

Python-based tools indeed hold a special place among developers, given their widespread acceptance. Spark's integration with Python, notably through PySpark, has witnessed tremendous growth. The adoption of PySpark, leveraging the powerful combination of Spark with Python, has surged notably.

Despite these challenges, Python-based ETL tools can be a valuable option for organizations that have the necessary skills and resources. By carefully evaluating your team's expertise and capabilities, you can determine if Python-based ETL tools are the right choice for your organisation.

Python ETL: My secret weapon! Wrangling data from spaghetti western to graceful ballet. ?? Diverse sources, Pandas power, open-source freedom, flexible scheduling, and a supportive community keep data flowing like a well-oiled machine. Ditch the blues, embrace the revolution!

Python based tools like Pyspark, Pandas, etc. are more flexible to use and currently are in trend in market. They can be integrated with cloud based applications easily.

For easy handling of the large volume of data in ETL processes, we can start using the combinations/mix of multiple things than the single approach., For example if we take Azure data bricks- we can benefit from cloud(azure), distributed computing(spark), language to work with spark-SQL, Pyspark and automated workflow orchestration (data bricks/ADF). This makes easy to work with benefits like unified & collaborative analytics platform and less/no maintenance on infra end. In this way, we can also enhance scalability, security and efficiency in DE workflows.

Selecting the right data integration tool is always a challenging task. Without a scalable and secure platform underneath it, the tool would solve only one problem: ease the use. The key is to determine the value they bring to ensure that they modernize the organization's analytics.

In my opinion, tools to be used should be based on the use cases for what the ETL will be used. it should consider the downstream usage / the kind of consumption layer required/ tools that will be used for consuming data / the infra on where the data will be stored / the security & encryption needs. Be it SQL based, or python based or cloud it is necessary to evaluate and determine the data needs to decide on the approach and tools

Es ist sinnvoll, die Gesamtarchitektur zu betrachten und das bestm?gliche Tool für sich zu finden um gro?e Datenvolumina zu verarbeiten. Auch, wenn ich aus der SAP Landschaft komme, gibt es Tools wie Syniti, die ebenfalls eine Daseinsberechtigung haben im Rahmen einer S/4HANA Transformation oder Erweiterung zu einer cloudbasierten L?sung.
