It is a huge responsibility, working with data, because there can be conflicts, it can become corrupted by other sources and so on. Data engineering experts worth their mettle will know how to test and plan systems out in order to find, and filter the junk data, eradicate duplicate data and manage incompatibility. They will also be able to preserve the clarity of the data when encrypting sensitive information. You should definitely look for someone who is proficient in Scala/Java and Python and DevOps.
Further, a knowledge of NoSQL and SQL databases is ideal along with MapReduce and similar concepts. Knowledge of data storage frameworks and technologies is also ideal for building pipelines.
Data pipelines can be fragile in nature and ideal Data engineers will be able to foresee these probable problems and pre-plan a solution route for them beforehand.
Here are a few factors that most good Data engineering experts would keep in mind:
The source data changes need to be kept in mind, so that the data pipelines remain clean. Keeping in mind the ...
... changing criteria of schemes and structures and adapting accordingly.
Unexpected outcomes can be avoided with the help of pipelines as they transform the output of one process into the input of the upcoming process.
Since the regular modifications of pipelines can cause downstream issues, ETL engineers make sure to keep monitoring and testing in order to catch hold of any errors.
Inaccurate data and errors can lead to breakage of pipelines, so data engineers need to have access to reliable tools in order to be able to find an resolve such issues.
With increasing data size, the complexity of pipelines also increases which in turn leads to slowed down speeds for processing. Data engineers have a set process to assess, improve and optimize performance.
Data engineers deal with scaling a pipeline, processing steps, input data size, parallelized data and 3rd party service invocations.
