The Future of Data Warehousing
As every company becomes a data company, and more users within these organizations are discovering new uses for previously unavailable data, existing infrastructure and tools are not just meeting that demand but creating new demands. At the center of it all is the data warehouse, the lynchpin of any modern data stack.
In this blog post, we’ll look at five innovations that are shaping the future of the data warehousing, as well as challenges and considerations that organizations should keep in mind.
We’ll take a peek into our predictions for the future of data warehousing in the following areas:
- 1. Data lake and data warehouse convergence
- 2. Easier to stream real-time data
- 3. Zero-copy data sharing
- 4. Zero ETL?
- 5. Data issues identified and resolved faster
- A bright and rapidly evolving future
1. Data lake and data warehouse convergence
The data lake vs data warehouse question is constantly evolving.
The maxim that data warehouses hold structured data while data lakes hold unstructured data is quickly breaking down. Both have expanded their capabilities to support what the other does. Data warehouses like Snowflake or Google BigQuery have made improvements integrating streaming data capabilities while Databricks has added ACID properties via delta tables and its new Unity Catalog.
The result will be a convergence toward what’s called a “data lakehouse,” a best-of-both-worlds approach that will allow many more organizations to benefit from the business intelligence to be found within their data footprint.
2. Easier to stream real-time data
As data needs have changed, standards for data freshness and latency have come closer to real time. In industries like finance, ecommerce, and manufacturing, we’re going to see the rise of solutions that reduce the complexity of writing code to build real-time streaming pipelines.
Solutions like Confluent with Databricks allow organizations to prep, join, enrich and query streaming data sets in Databricks SQL, which they claim has up to 12x better price-performance than a traditional data warehouse. Snowflake has also refactored their Kafka connector so that when data lands it is queryable immediately resulting in a 10x lower latency.
3. Zero-copy data sharing
Snowflake zero-copy cloning hints at the future of data warehousing.
Reducing the risks, costs, and headaches from traditional sharing methods, the feature allows organizations to share read-only database objects with other organizations without transferring the actual data.
A huge benefit is the separation of storage and compute. When an object is shared with a data consumer, it remains within the provider’s account, and the consumer incurs compute costs for querying the data, but no storage costs.
Not to be outdone, Databricks introduced its own zero copy data sharing capability with Delta Sharing, described as, “the world’s first open protocol for secure data sharing, making it simple to share data with other organizations regardless of which computing platforms they use.”
4. Zero ETL?
Beyond zero-copy data sharing, Amazon (AWS) has a grander vision for a zero ETL future altogether. At their last re:Invent event they announced Amazon Aurora now supports zero-ETL integration with Amazon Redshift, giving users the ability to move data between the two platforms without having to extract, transform and load first.
Currently only in limited preview, it’s unclear how much of a step up from the traditional ETL process this zero ETL future will be or whether it ends up just a gimmick with limited use.
For example, how easy will it be to perform complex data transformations? How will data governance be handled? And how hard will it be to interact outside of the zero ETL ecosystem?
We’ll have to see what the future holds.
5. Data issues identified and resolved faster
No matter what the future of data warehousing holds, if your users can’t rely on the underlying data itself, all of these innovations are for nothing.
Enter data observability platforms, which enable data teams to deliver more reliable and trustworthy data by operationally monitoring the health of data as it flows through the stack. These solutions dramatically reduce data downtime up to 80% or more by reducing the number of data issues, time to detection, and time to resolution.
The most successful data-driven companies already take advantage of these solutions, and data observability will only become more critical as every company becomes a data company.
A bright and rapidly evolving future
Data warehouses are at an exciting point of expansion and evolution. With the global data warehousing market size estimated to grow at a CAGR of 10% until 2028, you’ll see a greater reliance on them and the tools that make them easier to use than ever before.
