Is Hdfs a data lake?
A data lake is an architecture, while Hadoop is a component of that architecture.
In other words, Hadoop is the platform for data lakes.
For example, in addition to Hadoop, your data lake can include cloud object stores like Amazon S3 or Microsoft Azure Data Lake Store (ADLS) for economical storage of large files..
Can I use Kafka as database?
The main idea behind Kafka is to continuously process streaming data; with additional options to query stored data. Kafka is good enough as database for some use cases. However, the query capabilities of Kafka are not good enough for some other use cases.

Is Kafka a data warehouse?
Kafka is rapidly becoming the storage of choice for streaming data, and it offers a scalable messaging backbone for application integration that can span multiple data centers. Fundamental to Kafka is the concept of the log; an append-only, totally ordered data structure.
What is the difference between a data lake and a data warehouse?
A data lake is a vast pool of raw data, the purpose for which is not yet defined. A data warehouse is a repository for structured, filtered data that has already been processed for a specific purpose. The two types of data storage are often confused, but are much more different than they are alike.
What exactly is a data lake?
A data lake is a centralized repository that allows you to store all your structured and unstructured data at any scale.
Is Kafka Big Data?
Kafka is used for real-time streams of data, to collect big data, or to do real time analysis (or both). Kafka is used with in-memory microservices to provide durability and it can be used to feed events to CEP (complex event streaming systems) and IoT/IFTTT-style automation systems.
Is Snowflake a data lake?
Snowflake and Data Lake Architecture By mixing and matching design patterns, you can unleash the full potential of your data. With Snowflake, you can: Leverage Snowflake as your data lake to unify your data infrastructure landscape on a single platform that handles the most important data workloads.
Is a data lake a database?
Database and data warehouses can only store data that has been structured. A data lake, on the other hand, does not respect data like a data warehouse and a database. It stores all types of data: structured, semi-structured, or unstructured.
Can Kafka be used for ETL?
Companies use Kafka for many applications (real time stream processing, data synchronization, messaging, and more), but one of the most popular applications is ETL pipelines. … You can use Kafka connectors to read from or write to external systems, manage data flow, and scale the system—all without writing new code.
Why is it called a data lake?
Data Lake. Pentaho CTO James Dixon has generally been credited with coining the term “data lake”. He describes a data mart (a subset of a data warehouse) as akin to a bottle of water…”cleansed, packaged and structured for easy consumption” while a data lake is more like a body of water in its natural state.
Can Kafka replace ESB?
Apache Kafka: An Open Source Event Streaming Platform Integration and Stream Processing are still key functionality but can be realized in real time natively instead of using additional ETL, ESB or Stream Processing tools.
