Excellent content! It looks like the Iceberg + StarRocks open lakehouse Architecture is highly effective.

Great article, thank you for sharing! I have a question I’d like to discuss with the author. Spark SQL is a great product and works perfectly for batch processing tasks. However, for handling ad hoc query tasks or more interactive data analysis tasks, Spark SQL might have some performance issues. If you have such workloads, I suggest trying data lake query engines like Trino or StarRocks, which offer faster speeds and a better query experience.

HermitX — Tue, 04 Jun 2024 18:20:50 +0000

I believe Snowflake not only needs an open-source table format but also an open-source data lake query engine. Currently, Snowflake has too little presence in this area, and its stock price is reaching new lows.

I suggest you try using StarRocks to query the data lake directly. I know many large companies, including Tencent and Pinterest, are doing this. StarRocks has a truly mature vectorized execution engine and a robust distributed architecture. It can provide you with impressive query performance.

New comment by HermitX in "Using ClickHouse to scale an events engine"

HermitX — Thu, 11 Apr 2024 20:47:05 +0000

Is ClickHouse a suitable engine for analyzing events? Absolutely, as long as you're analyzing a large table, its speed is definitely fast enough. However, you might want to consider the cost of maintaining an OSS ClickHouse cluster, especially when you need to scale up, as the operational costs can be quite high.

If your analysis in Postgres was based on multiple tables and required a lot of JOIN operations, I don't think ClickHouse is a good choice. In such cases, you often need to denormalize multiple data tables into one large table in advance, which means complex ETL and maintenance costs.

For these more common scenarios, I think StarRocks (www.StarRocks.io) is a better choice. It's a Linux Foundation open-source project, with single-table query speeds comparable to ClickHouse (you can check Clickbench), and unmatched multi-table join query speeds, plus it can directly query open data lakes.

New comment by HermitX in "Velox: Meta's Unified Execution Engine [pdf]"

HermitX — Tue, 26 Mar 2024 00:05:56 +0000

To the best of my knowledge, Meta has significantly reduced its investment in the Velox project. Apart from Meta, I'm not aware of any other major company that really uses Velox in a production environment. Frankly speaking, Velox may have already missed the window of opportunity for rapid development. If you're looking for a vectorized execution engine, you could consider ClickHouse (www.clickhouse.com) or StarRocks (www.starrocks.io). If your data analysis scenarios require more multi-table join operations, StarRocks is clearly a better choice.

I This is an intriguing article, clearly showing the team's fondness for Postgres. However, Postgres is an OLTP product. I'm curious about what system Figma's data team uses for their data analysis tasks.
