Top Data Lake Tools/Solution for Data Science Research in 2022

Most of the data is kept in a “data lake,” a centralized and unprocessed area. A data lake uses a flat design and object storage to store the data instead of a hierarchical data warehouse, which arranges the data into files and folders. Data is stored in object storage with metadata tags and a unique identifier, which enhances performance and makes it simpler to find and retrieve data across regions. Data lakes make it possible for numerous apps to use the data by utilizing open standards and cheap object storage.

Although data warehouses offer businesses very effective and scalable analytics, they are costly, proprietary, and unable to handle the current use cases that most companies are looking to address. As a result of data warehouses’ shortcomings, data lakes were created. Data lakes enable storing all of an organization’s data in a single, central location where it can be preserved “as is,” in contrast to a data warehouse which imposes a schema up front, which is a structured arrangement of the data.

All data types, including unstructured and semi-structured data like images, audio, video, and documents, may be processed by data lakes, which is crucial for today’s machine learning and advanced analytics use cases. A data lake can hold data at all phases of the refinement process, including intermediate data tables created during the refinement of raw data. Along with an organization’s structured, tabular data sources, unstructured data can be ingested and stored (such as database tables). As opposed to the majority of databases and data warehouses, this.

The purpose of using a data lake

A data lake is an obvious choice for data storage due to its unique capacity to absorb raw data in several formats (structured, unstructured, and semi-structured), as well as the other advantages mentioned. Customers are less likely to be forced to adopt a proprietary solution like a data warehouse because data lakes are open-format, which is more crucial in modern data infrastructures. Because they can grow and use object storage, data lakes are also very affordable and durable. Additionally, sophisticated analytics and machine learning on unstructured data is among businesses’ top strategic concerns.

Infor Data Lake

The Infor Data Lake solution gathers data from many sources and ingests it into a structure that immediately begins to extract value from it.

Key characteristics of Infor Data Lake:

• Infinite scrolling of the store would still allow for the most intelligent choices to be made using the most enriched data that can be included in ML algorithms.
• It won’t ever become a swamp where your data is stored. Your data should be intelligently cataloged to guarantee that understanding is never lost.
• The relational layer created by Infor’s Data Lake Metagraph creates extensive connections between multiple data types and datasets. In the latter stages, this can be used to draw a wise conclusion.

Intelligent Data Lake

With the help of Informatica’s Intelligent Data Lake, users can get the most out of their Hadoop-based data lake.

Other data solutions are supported, including Microsoft Azure SQL Database, AWS Redshift, Amazon’s Aurora, and SQL Data Warehouse.

Key characteristics of Intelligent Data Lake

• Using large-scale data searches won’t require much coding because of the underlying Hadoop framework.
• Detail relations between various data sets can be constructed using a graph-based processing engine to provide more clarity about the entities that are essential to your organization.

Cloudera data lake service

A big data processing platform built in the cloud called Cloudera Data Lake Service aids in businesses’ efficient management, processing, and analysis of enormous amounts of data. ETL, data warehousing, machine learning, and streaming analytics are just a few of the workloads for which the platform is well suited because of its ability to manage both organized and unstructured data.

Additionally, Cloudera offers the Cloudera Data Platform (CDP), a managed service that makes it simple to install and maintain data lakes in the cloud. Because it provides a wide range of features and services, it is one of the best cloud data lake options.

Key characteristics of Cloudera data lake service

• Petabytes of data and thousands of different users can be handled using CDP.
• Cloudera governance and data log features transform metadata into information assets, which also increase its usefulness, dependability, and value over the course of its life cycle.
• Users can control encryption keys, and data can be encrypted at rest and while in motion.
• In addition to defining and enforcing configurable, role- and attribute-based security rules, Cloudera Data Lake Service also prevents and audits illegal access to sensitive or restricted data.
• End users can access the platform with just one sign-on (SSO) through the secure access gateway of Apache Knox.

Google BigLake
