We've been having some issues with intermittent performance on multi hop queries.

What's your p99 like for multi hops?

View on HN

In prod we see p99’s of <10ms ms for warm queries and around 50ms per hop for cold queries.

Hmmm... I'll get in touch. Got an email i can reach out to, there doesn't seem to be one listed on your website?

I'm more concerned about if the p99s stay consistent when things get spikey.

dgraph is fine otherwise...

Sure! You can email me personally at george@helix-db.com

If your use case is OLAP based, please check it out PuppyGraph. It’s a graph query engine that sits on top of your Lakehouse (no ETL required). Our benchmark has shown consistently that 10-hop queries across billions of edges in <2 seconds. Our customers including some most data demanding companies like Coinbase, Datadog, Palo Alto Network, Netskope, AMD, etc.

PuppyGraph is a good fit for OLAP for sure.

We’re just two young founders sharing what we’ve been building, so I’ll take the drive-by competitor plug as a compliment :)

Definitely a different focus though. Helix is OLTP, built for operational graph + vector workloads, especially apps/agent memory where low-latency traversals and writes are concerned.

And is open source.

where is puppygraph's source code?

puppy graph is not open source

It's not, its actually our prod db with direct user usage - we self host a large dgraph cluster. We have a very large number of people manage their car and car histories with us and host a full replica of the UK MOT Database.

We're fine with clickhouse and redshift for the OLAP work we do. I've been looking at ParaQuery lately if I really want to speed that up.

This sounds like a perfect usecase. Would love to learn more and see if we can help!
