Larger orgs definitely need master data items (dimensions) to ensure consistency when conducting cross-data-subject analysis. But many orgs will continue to have a shared repository of business information/Data for reporting and analysis.Ĥ: Hard disagree. No sound definition exists.ģ: It might not be called a "Data warehouse" but rather a Data Platform or similar. Centralised governance is still quite important thoughġ: Data warehouses moving to the cloud - Agree.Ģ: Data mesh is something made up by new vendors to try and sell their product.
Databricks has now the Lakehouse and, this week, Snowflake presented a similar thing in their online event. Vendors will invest money in bringing all the different roles (Data Engineers, Data Analysts and Data Scientists) back to a centralised platform.I see it more going into the direction of continuous data flow with things like CDC with Kafka or Pub/Sub pumping data into the ingestion layer. The approach you mentioned in your question sounds still like a batched way of loading data into the data warehouse. The data models are also smaller and I think conformed dimensions won't make so much sense anymore, as each domain might have its own semantics.They can still be in the same stack though (like a Lakehouse).

What I noticed, mostly by searching for new position is: I guess I still not agree with dbt guy and cloud data mesh guy. Much more stringency of checking data quality and referential integrity because of the ability to create loads of tables.ĩ) specialised ASICS like aqua from redshift will become the defining characteristic of a warehouse for performance in the next 5 years.ġ0) the rise of what people are calling “the metric layer” just search google for Airbnb tech blog data metric. dbt tests, unlimited storage allowing blue green deployments. This goes hand in hand with tools like dbt as of you have an explosion of new sources you need some way to trace where everything is coming from.Ħ) data science processing starting to move more into the warehouse for mere mortal companies to take advantage of, bigquery, redshift and snowflake all offer something like this.ħ) the cloud vendors starting to move more towards the kitchen sink approach, like I mentioned with the data science stuff, most of them have services for getting data from common data sources (think other databases, salesforce etc)Ĩ) more software engineering principles penetrating the build and design of a warehouse, e.g. See tools like data hub and amusden for examples. This has been transformative in every company I’ve either implemented it in or seen it implemented.ĥ) data lineage starting to become more viable for companies which aren’t all in on one massive vendor who do the kitchen sink approach. 1) Cloud data warehouses with decoupled storage and compute, snowflake, spark, redshift take your pick.ģ) streaming will start to “quiet down” as the initial hype has passed and most companies now understand that they don’t need to jump on that train.Ĥ) dbt, allowing analytics engineers and analysts to have a greater freedom over the tables they build without data engineering becoming a bottle neck (unlimited storage makes this possible).
