Data lakes and datawarehouses are two of the most important data storage and management technologies in a modern data architecture. Data lakes store all of an organization’s data, regardless of its format or structure. Delta Lake doesn’t have a specific concept for incremental queries.
Complex queries, on the other hand, refer to large-scale data processing and in-depth analysis based on petabyte-level datawarehouses in massive data scenarios. AWS Glue crawler crawls data lake information from Amazon S3, generating a Data Catalog to support dbt on Amazon Athena data modeling.
This post was co-written with Dipankar Mazumdar, Staff Data Engineering Advocate with AWS Partner OneHouse. Data architecture has evolved significantly to handle growing data volumes and diverse workloads. Querying all snapshots, we can see that we created three snapshots with overwrites after the initial one.

and zero-ETL support) as the source, and a Redshift datawarehouse as the target. The integration replicates data from the source database into the target datawarehouse. Additionally, you can choose the capacity, to limit the compute resources of the datawarehouse. For this post, set this to 8 RPUs.
The AWS Glue crawler generates and updates Iceberg table metadata and stores it in AWS Glue Data Catalog for existing Iceberg tables on an S3 data lake. Snowflake integrates with AWS Glue Data Catalog to retrieve the snapshot location. Snowflake can query across Iceberg and Snowflake table formats.
Expire snapshots Each write to an Iceberg table creates a new snapshot , or version, of a table. Snapshots can be used for time-travel queries, or the table can be rolled back to any valid snapshot. This action might take a long time to complete if there are a large number of files in the data and metadata directories.
These formats enable ACID (atomicity, consistency, isolation, durability) transactions, upserts, and deletes, and advanced features such as time travel and snapshots that were previously only available in datawarehouses. It will never remove files that are still required by a non-expired snapshot.
The general availability covers Iceberg running within some of the key data services in CDP, including Cloudera DataWarehouse ( CDW ), Cloudera Data Engineering ( CDE ), and Cloudera Machine Learning ( CML ). Cloudera Data Engineering (Spark 3) with Airflow enabled. Cloudera Machine Learning . group by year.
We live in a data-producing world, and as companies want to become data driven, there is the need to analyze more and more data. These analyses are often done using datawarehouses. Status quo before migration Here at OLX Group, Amazon Redshift has been our choice for datawarehouse for over 5 years.
Whenever there is an update to the Iceberg table, a new snapshot of the table is created, and the metadata pointer points to the current table metadata file. At the top of the hierarchy is the metadata file, which stores information about the table’s schema, partition information, and snapshots. all_reviews ): data and metadata.
Cloudera DataWarehouse (CDW) running Hive has previously supported creating materialized views against Hive ACID source tables. release and the matching CDW Private Cloud Data Services release, Hive also supports creating, using, and rebuilding materialized views for Iceberg table format.

The extract, transform, and load (ETL) process has been a common pattern for moving data from an operational database to an analytics datawarehouse. ELT is where the extracted data is loaded as is into the target first and then transformed. ETL and ELT pipelines can be expensive to build and complex to manage.
To achieve this, first requires getting the data into a form that delivers insights. Salesforce data is extracted, transformed and loaded into a datawarehouse using an ETL tool connected to the datawarehouse. Then, use a data model to model the data into a single unified source of truth.
They enable transactions on top of data lakes and can simplify data storage, management, ingestion, and processing. These transactional data lakes combine features from both the data lake and the datawarehouse. The Data Catalog provides a central location to govern and keep track of the schema and metadata.
