In the previous blog posts in this series, we introduced the N etflix M edia D ata B ase ( NMDB ) and its salient “Media Document” data model. NMDB is built to be a highly scalable, multi-tenant, media metadata system that can serve a high volume of write/read throughput as well as support near real-time queries.
In terms of data analysis, as soon as the front-end visualization or BI tool starts accessing the data, the CDW Hive virtual warehouse will spin up cloud computing resources to combine the persisted historical data from the cloudstorage with the latest incremental data from Kafka into a transparent real-time view for the users.
We recently completed a project with IMAX, where we learned that they had developed a way to simplify and optimize the process of integrating Google CloudStorage (GCS) with Bazel. In this blog post, we’ll dive into the features, installation, and usage of rules_gcs , and how it provides you with access to private resources.
Foundational to the data fabric are metadata driven pipelines for scalability and resiliency, a unified view of the data from source through to the data products, and the ability to operate across a hybrid, multi-cloud environment. . The post Demystifying Modern Data Platforms appeared first on Cloudera Blog.
In the case of CDP Public Cloud, this includes virtual networking constructs and the data lake as provided by a combination of a Cloudera Shared Data Experience (SDX) and the underlying cloudstorage. Further auditing can be enabled at a session level so administrators can request key metadata about each CML process.
It serves as a foundation for the entire data management strategy and consists of multiple components including data pipelines; , on-premises and cloudstorage facilities – data lakes , data warehouses , data hubs ;, data streaming and Big Data analytics solutions ( Hadoop , Spark , Kafka , etc.);
The architecture is three layered: Database Storage: Snowflake has a mechanism to reorganize the data into its internal optimized, compressed and columnar format and stores this optimized data in cloudstorage. Snowflake allows the loading of both structured and semi-structured datasets from cloudstorage.
DataHub 0.8.36 – Metadata management is a big and complicated topic. DataHub is a completely independent product by LinkedIn, and the folks there definitely know what metadata is and how important it is. If you haven’t found your perfect metadata management system just yet, maybe it’s time to try DataHub!

This activity is rather critical of migrating data, extending cloud and on-premises deployments, and getting data ready for analytics. In this all-encompassing tutorial blog, we are going to give a detailed explanation of the Copy activity with special attention to datastores, file type, and options. can be ingested in Azure.
One is data at rest, for example in a data lake, warehouse, or cloudstorage and from there they can do analytics on this data and that is predominantly around what has already happened or around how to prevent something from happening in the future.
To prevent the management of these keys (which can run in the millions) from becoming a performance bottleneck, the encryption key itself is stored in the file metadata. Each file will have an EDEK which is stored in the file’s metadata. However, we can continue without enabling TLS for the purpose of this blog.
If you want to follow along and execute all the commands included in this blog post (and the next), you can check out this GitHub repository , which also includes the necessary Docker Compose functionality for running a compatible KSQL and Confluent Platform environment using the recently released Confluent 5.2.1.
