Find out what your peers are saying about Databricks, Microsoft, Alteryx and others in Data Science Platforms."Everyone uses Dremio in my company; some use it only for the analytics function."
"The most valuable feature of Dremio is it can sit on top of any other data storage, such as Amazon S3, Azure Data Factory, SGFS, or Hive. The memory competition is good. If you are running any kind of materialized view, you'd be running in memory."
"We primarily use Dremio to create a data framework and a data queue."
"Dremio enables you to manage changes more effectively than any other data warehouse platform. There are two things that come into play. One is data lineage. If you are looking at data in Dremio, you may want to know the source and what happened to it along the way or how it may have been transformed in the data pipeline to get to the point where you're consuming it."
"Dremio allows querying the files I have on my block storage or object storage."
"Dremio gives you the ability to create services which do not require additional resources and sterilization."
"It’s good for quick visualization and being able to quickly consume unstructured data to play around with."
"It allows us to basically understand and evaluate our numbers in an expedient manner."
"Tableau has data relationships that can be applied to a data source which helps build out a directory which is helpful. Data blending has also been valuable to us."
"The solution allows for the possibility for end-users to do their own reporting."
"It has made the reporting stage simple and enabled us to focus mainly on the ETL part"
"The most valuable feature is the aggregation function."
"Tableau is easy to use compared to some other solutions, such as Excel."
"The most valuable part of the solution is the general dashboard features."
"Dremio takes a long time to execute large queries or the executing of correlated queries or nested queries. Additionally, the solution could improve if we could read data from the streaming pipelines or if it allowed us to create the ETL pipeline directly on top of it, similar to Snowflake."
"We've faced a challenge with integrating Dremio and Databricks, specifically regarding authentication. It is not shaking hands very easily."
"They have an automated tool for building SQL queries, so you don't need to know SQL. That interface works, but it could be more efficient in terms of the SQL generated from those things. It's going through some growing pains. There is so much value in tools like these for people with no SQL experience. Over time, Dermio will make these capabilities more accessible to users who aren't database people."
"I cannot use the recursive common table expression (CTE) in Dremio because the support page says it's currently unsupported."
"Dremio doesn't support the Delta connector. Dremio writes the IT support for Delta, but the support isn't great. There is definitely room for improvement."
"It shows errors sometimes."
"The customization requires a lot of effort and should be simplified. The performance could be better."
"The price of Tableau is too high."
"Lacks machine learning algorithms that you can implement using R, SPSS Modeler, and Python."
"An area needing improvement involves the complexity of the product should you need to alter a lot of parameters. If you have technical servers, much interface, different providers and more serious processes, that will be time consuming."
"The interface can be improved, in part because there is no indication that something is running or that it's processing."
"The product needs to allow for better ways to drill down more effectively on the information at hand."
"There's no mature ETL tool in Tableau, which is quite a negative for them."
"It will be good if the server, could be more stable, and I would like to have the technical service to be more reliable."
