Matillion Interview Questions And Answers

Matillion Basic Interview Questions:

1) What is ETL?

ETL (extraction, transformation, & loading)  is a three-step data processing methodology wherein the data gets extracted from the source and extracted data will be converted into the required format, and in the final stage the data will be dumped into a targeted location.  ETL plays a key role in the data engineering space. 

2) What is ELT?

ELT stands for Extract, Load, and Transform and is used for processing data. In this method, it extracts data from the source and loads it directly into the destination i.e. data lake or data warehouse. The transformation process takes place at the end.

3) What is Matillion?

Matillion is a cloud-based data integration platform that offers powerful features required to perform end-to-end data transformation operations. It is built for the cloud and is flexible to work with all three top cloud data warehouse platforms such as  Redshift, Snowflake, Google BigQuery, Delta Lake, and Azure Synapse.

Matillion is a modern ETL/ELT cloud platform that comes with an easy-to-interact browser-based user interface. Moreover, it comes with advanced connectors to connect to different data sources.

4) What is Orchestration?

Data orchestration is an automatic method that connects various data sources either cloud or legacy systems and organizes information that is useful for analytics.

5) What is a data Pipeline?

In data engineering data pipeline is a data transportation mechanism from source to destination. A pipeline can ingest data from source systems and this data goes through multiple stages in the pipeline and is then stored in the target location. Majorly there are two types of pipelines available which are batch data pipelines, and streaming data pipelines.

6) What is Change Data Capture (CDC)?

Change Data Capture (CDC) is a method that helps users to have access to accurate information. CDC identifies the changes made to the database and updates the same in the downstream process. This will eliminate data mismatch issues.
