Dremio gives you the ability to create services which do not require additional resources and sterilization.

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.

Everyone uses Dremio in my company; some use it only for the analytics function.

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.

We primarily use Dremio to create a data framework and a data queue.

Dremio is very easy to use for building queries.

It's almost similar, yet it's better than Starburst in spinning up or connecting to the new source since it's on SaaS.

Dremio has positively impacted my organization by helping us create a single source of truth, a singular data warehouse where we can have access to all of the data sets.

The first feature that stands out for me in Dremio is the federated type of query, which allows the possibility to use multiple endpoints without worrying about writing custom SQL that runs only for SQL Server or for Postgres and Redshift.

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.

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.

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.

We've faced a challenge with integrating Dremio and Databricks, specifically regarding authentication. It is not shaking hands very easily.

I cannot use the recursive common table expression (CTE) in Dremio because the support page says it's currently unsupported.

There are performance issues at times due to our limited experience with Dremio, and the fact that we are running it on single nodes using a community version.

They need to have multiple connectors.

Dremio could be improved by making it easier for data cataloging, especially when working with open table formats, as you have to choose a data format and then go into it.

We had a memory leak on some versions, which sometimes stopped the service.
