I build tools that process big data and compute.
I am currently working on Velox and Prestissimo.

@auxten I would recommend Andy Pavlo's courses as well. https://t.co/kgpLTcLKXw

@PedroERPedreira, Orri, and I will present a composable data management tutorial focusing on the execution layer at VLDB 2024. We will use Velox to explain the core concepts and cover DataFusion, Photon.

@andy_pavlo @OtterTuneAI Sorry to hear this, Andy.

Columnar file formats like Parquet/ORC are ubiquitous. Our VLDB paper with @XinyuZeng218 + @huanchenzhang + @wesmckinn studies their internals.

TLDR: They're not optimized for modern hardware. Something new is needed.

@andrewlamb1111 @wesmckinn @andy_pavlo @XinyuZeng218 @huanchenzhang @ApacheParquet @apacheorc Another issue we see with Parquet is that we cannot track the thrift deserialization memory consumption via a memory pool. This causes OOMs.

[Deepak Majeti @majetideepak]

@_Felipe Very impressive!

[Deepak Majeti @majetideepak]

@andrewlamb1111 @J_ Vertica and Arrow developers also collaborated on the C++ Parquet library implementation.

This is the future of databases. It is too expensive / time-consuming to build a DBMS from scratch.
🡲 If you want a new OLAP DBMS, start with Velox / Arrow+@VoltronData / Clickhouse / @duckdb.
🡲 If you want a new OLTP DBMS, start with @PostgreSQL / @RocksDB / @WiredTigerInc.

[Deepak Majeti @majetideepak]

@andy_pavlo @ApacheArrow Velox has its own columnar format which is @ApacheArrow "compatible" in most cases.

Today's Vaccination Database Speaker: Dr. Deepak Majeti (@majetideepak) from @AhanaIO will present the Velox execution engine for @PrestoDB. Zoom talk is open to public at 4:30pm ET. YouTube video will be available afterwards: https://t.co/REWhVqX4tT

@sonnes Stay strong! You will get through this.

[Deepak Majeti @majetideepak]

If you need or love building high-performance distributed systems, checkout Velox

Just read @vardi 's thought provoking thoughts "The Sand-Heap Paradox of Privacy and Influence" in the recent CACM.

The irony of the last sentence "Follow me on ..." and my own post on Twitter is duly noted.

Thoroughly enjoyed reading Sapiens by @harari_yuval

[Moshe Vardi @vardi]

Nerd joke :-)

Just finished watching @SocialDilemma_ documentary on Netflix on social media and what it is doing to us. Some thoughts:

1. Loved this quote by @tristanharris that went something like "How can you wake up from the matrix, when you don't even know you're in it?"

[Deepak Majeti @majetideepak]

"THE GENE: An Intimate History" and "The Emperor of All Maladies: A Biography of Cancer" piqued my curiosity in genetic research. Thanks, @DrSidMukherjee for the great read.
