“The objective was to build a new system from the ground up, to scale not only beehiiv’s data platform, but ideally the business as a whole,” Eric says.

“We’re a company that tries to ingest as much data as possible to make optimization decisions, which can be a recipe for rising costs,” Marco says. “ClickHouse Cloud makes that process so efficient, and the price point is so much lower, we can actually look forward to ingesting more data into our systems while keeping costs relatively at bay.”

“Compared to other solutions we explored and what we had before, ClickHouse just blows them away,” Zeev says. “It’s very, very cheap, and the quality is extremely high.”, Zeev Feldbeine, Principal Data Engineer at Vimeo

“At Coinhall, managing vast amounts of blockchain data efficiently is crucial for our consumer-facing trading platform. Initially, we used BigQuery, but as our data grew, so did its costs and performance issues. After exploring several alternatives, we found ClickHouse to be the clear winner. ClickHouse significantly outperformed other databases we tested like Snowflake, Rockset, and SingleStore, and delivered at 40x cost savings.”

“The system manages to store over 10 billion rows spanning four years in less than 325 GB on disk”

“The query performance was just blazing fast. I couldn't believe it. I had to go back a couple of times just to make sure I was querying it properly.”

“When you’re doing interactive analysis of an AI product, an engineer can’t run something and then wait for five minutes”

“ClickHouse has proved to be a game-changer, propelling us towards greater efficiency and effectiveness in managing our data infrastructure.”

“ClickHouse looked good for their use case of supporting 10-million-member records with 100 fields each: We had a billion rows to store.”

“Adopting ClickHouse has enhanced our data analytics capabilities, supporting the growing demands of our internal teams efficiently and cost-effectively.”

OpenMeter team has developed a scalable, robust metering system capable of handling millions of billable events per second, built on top of ClickHouse Cloud.

Trip.com migrated from Elasticsearch and built a 50PB logging solution with ClickHouse. Storage space savings exceeded 50%, enabling the existing Elasticsearch servers to support a 4x increase in data volume with ClickHouse. Query speed is 4 to 30 times faster than ElasticSearch, with a P90 of less than 300 ms and a P99 of less than 1.5s.

“We want to be able to handle a wide variety of different data pipelines and code tasks. Ultimately, the goal is to enable whatever deployment and trigger patterns developers, data engineers, platform engineers, and software engineers need,” and this is why ClickHouse has become integral to Prefect

In this talk -- given at the ClickHouse NYC Meetup on April 26, 2023 -- Brooke McKim (Co-founder and CTO of Vantage) shares their journey from Redshift to ClickHouse Cloud.

“As we became more popular, we began ingesting millions of events every minute. Our rudimentary Postgres-only stack—which had served us well in the early days—wasn’t cutting it.”

“The benefits were immediate, with faster data processing and accurate analytics that allowed me to make strategic decisions with confidence. ClickHouse opened new horizons for the growth and success of my company, raising our executive vision to levels never reached before.”

“We evaluated more than a dozen different big data systems before settling on ClickHouse. No system comes close to ClickHouse when it comes to the flexibility ClickHouse provides.”

“With ClickHouse, the data pipeline logic is simplified, and is only dealing with the “streaming” aspect of the write as opposed to all of these complexities. ClickHouse thus enables a simpler write design pattern just like any other new age data lake systems like Hudi etc. but with a more simplistic developer experience.”

“We use ClickHouse Cloud to monitor millions of real-time web performance data points, to ensure we’re getting faster all the time. The platform delivers fast and reliable data management, while also proving to be cost efficient and user-friendly.”

“Moving from Elasticsearch to ClickHouse was a long journey, but this is one of the best tech decisions we ever took.”

“With dbt execution orchestrated in various intervals, we can also leverage ClickHouse for internal BI use cases. We’ve found this setup very practical, as we can flexibly create new analytical views of our customer data without moving it from our production operational systems.”

“With Snowflake, we were using the standard plan, small compute, which cost nearly six times more than ClickHouse Cloud. We got several seconds query time and no materialized views. With ClickHouse Cloud’s production instance, we are getting sub-second query time along with materialized views. The decision to switch was a no-brainer for us.”

“When we tested how much time the same reports would take with ClickHouse, people were amazed. We ran the same data, and in a blink of an eye, we had the results.“

“ClickHouse solves most of our problems very efficiently at a small fraction of the price in terms of infrastructure. This is a far better advantage for us in our books”

“We collect tens of thousands of data points from customers’ phones and other more traditional sources. ClickHouse is used as a way to process all of these SMS messages and extract valuable information used for the scoring and fraud models.“

“After Testing Hadoop and Spark, We Chose ClickHouse“

“We aggregate the user’s history in ClickHouse and use it as a data store for training and inference. Even when reading 10s of millions of rows, the performance was very nice and not the bottleneck when training new models.”

“ClickHouse was perfect as Big Data Storage for our ML models.”

“ClickHouse’s performance exceeds all other column-oriented database management systems. It processes billions of rows and tens of gigabytes of data per server per second”

“Migrating logs from Elasticsearch to ClickHouse has not only significantly reduced storage costs but also provided us with a faster querying experience.”

“In the post-evaluation of each database against our criteria (with metrics ranging from query performance to cost), ClickHouse emerged as the unrivalled frontrunner. It excelled across the board, even astonishingly so in certain domains, and proved more cost-efficient.”
