Databricks CEO Ali Ghodsi at Knowledge + AI Summit 2022 on June 28, 2022

Databricks CEO Ali Ghodsi turned some heads final week with a daring declare: Prospects can get 30x price-performance benefit over Snowflake when operating SQL queries in a lakehouse setup. Nonetheless, Snowflake waved off the assertion, claiming the comparability was all moist.

Databricks’ declare relies on an unpublished TPC-DS benchmark that it ran by itself knowledge analytics providing in addition to these of rivals. Ghodsi publicly shared the outcomes for the primary time throughout a press convention final week earlier than detailing the leads to his keynote handle on the Knowledge + AI Summit, which befell final week in San Francisco.

Databricks says the outcomes present the relative prices to run the TPC-DS 3TB benchmark on totally different cloud knowledge warehouses and lakehouses utilizing exterior Parquet tables.

Data offered by Databricks exhibits the job value $8 to run on “SQL L w/ desk stats,” which the corporate stated refers to its “giant warehouse” providing utilizing desk stats. That signifies that Databricks “ran the analyze desk assertion to permit the question optimizer to discover a simpler question plan,” Databricks’ Joel Minnick, vice chairman of selling, informed Datanami through e-mail. With out the desk stats offered by the question optimizer, the associated fee for the job went as much as $18.67.

When the identical job was run on different cloud knowledge warehouses, the associated fee elevated to $63.95, $74.77, $270, and $243.19. The primary three “CDWs” presumably confer with the three public cloud distributors—AWS, Google Cloud, and Microsoft Azure (we don’t know which of them are which). The graphic for CDW 4, nevertheless, bore Snowflake‘s emblem.

It’s essential to notice that Databricks ran the queries as if the opposite cloud choices have been lakehouses. Which means the info analyzed was contained in Parquet tables saved on a cloud object system. Querying knowledge from Parquet information saved in object storage basically eliminates the benefit that cloud knowledge warehouses can get by loading the info into the distinctive format utilized by columnar analytic databases, that are on the coronary heart of cloud knowledge warehouses.

Databricks ran the check for a few causes. First, it did it to point out off the work it has achieved in Delta Lake, which blends parts of knowledge warehouses and knowledge lakes, in addition to its Photon engine, the C++ rewrite of Spark SQL, which additionally grew to become typically obtainable on the present. Secondly, Databricks has change into a bit of miffed that its rivals have began calling themselves lakehouses, which the corporate’s management says waters down the which means of the time period.

“In the event you take a look at all the large cloud distributors, they’re all speaking about lakehouses,” Ghodsi stated throughout a press convention final week. “They declare they’re lakehouses. So we’ll use you as a lakehouse, which suggests we aren’t going to repeat the info inside of those methods. We’re going to retailer it on the lake, as a result of that’s the place lakehouses are, and we’ll entry it from there.”

Databricks shared info from a second benchmark that measured the price of loading and operating the TPC-DS 10TB check, which offered extra  of a good comparability from the cloud knowledge warehouse distributors’ factors of view, in line with Ghodsi.

Databricks charged $76 to load, auto-cluster, and question the info, whereas Snowflake charged $386 within the enterprise model and $258 in the usual model, representing a 5.1x and three.4x benefit for Databricks, the corporate’s knowledge confirmed.

A number of the extra work measured by the benchmark within the different 4 cloud knowledge warehouses was in loading the info into the warehouse, in line with Ghodsi. The benchmark additionally computed how a lot it value to optimize the tables. “That seems to be a major value,” he stated.

A few of these prices might be averted within the lakehouse, Ghodsi stated. “Utilizing the lakehouse, if you have already got your knowledge on a lake, you don’t must do the load portion,” he stated.

Snowflake refused to be drawn in, stating that it was centered on serving buyer wants, which incorporates delivering higher price-performance.

“We’re centered on innovating and delivering worth for our prospects,” Snowflake SVP of Product Christian Kleinerman informed Datanami. “Our worth efficiency is a key purpose that our prospects are migrating increasingly workloads to Snowflake, inclusive of Spark workloads. We’re constantly delivering new efficiency enhancements to make actual buyer workloads run sooner.

“We additionally consider in passing on the related financial financial savings to our prospects, which compounds the worth/efficiency advantages for them,” he continued. “We encourage anybody within the comparability to do their very own evaluation. We’ll proceed to remain centered on buyer outcomes.”

Smack-talking is a time-honored custom with regards to {hardware} and software program firms, and it might seem that Databricks is now doing its half to uphold the custom with the corporate that has change into its closest competitor.
