A few people I follow have left SF for NYC. I’m curious if anyone on HN has done the same and why.

These are refurbished.

This was done a few years ago. See https://web.archive.org/web/20150325003526/http://blog.found... .

What was the concurrency like in those benchmarks?

I wrote a blog post on how to implement secondary indexes using an ordered key-value store a couple of years ago: https://misfra.me/2017/01/18/how-to-implement-secondary-inde... It would work with FoundationD

I think they're built on a common storage system, just like the MySQL compatible version too.

Not sure why I'm getting downvoted. The characteristics sound exactly like Aurora. - "replicates six copies of your data across three AWS Availability Zones (AZs)" [0] - "Amazon DocumentDB uses a distributed, fault-toler

Sounds like this runs on the same storage service as Aurora.

How common is that though? Your example doesn’t necessarily make the parent comment wrong.

Yeah. You can treat the version as just another attribute to identify the series.
45.
by misframer 8y ago
Some of those we’ve looked at before and decided not to go with because of unknown observability, high operational requirements, or cost. But yeah, no real problems with data models or queries. I think Druid has come the closest to the most

I understand. Can you give an example of a “modern distributed relational column-oriented database”? Two capabilities that are important in my work are roll-ups (reducing resolution of data) and fast bulk deletes of old data.

> All the features you mentioned are already part of distributed column-oriented databases. I disagree, but even if that was the case, not all of them perform well. For example, we could've used Cassandra for our use case at my pr

It really depends. Capabilities like time-series-specific compression, automatic rollups, complex aggregations and/or ranking, stable storage in S3, clustering, and replication vary a lot and I think that's why we see so many TSDB

Their static file hosting is great too. Automatic Let’s Encrypt support!

RDS doesn't support extensions like TimescaleDB or (as someone else mentioned) Citus.

I don't miss the button. What didn't you like about the missing button?

TimescaleDB can’t do distributes joins like CrateDB as described in this post.

I haven’t been recruited that way but I have been contacted this way. I don’t have any experience with this process besides that. Why wouldn’t you go through a VC firm? I think it seems fine, but then again I’ve never been through the entir

This takes advantage of log-structured storage so there isn't any "undoing".
57.
by misframer 8y ago
Aurora uses a log-structured storage system, so they just point to a previous version that they haven't garbage collected.

Awesome! The TechCrunch article [0] shows "16GB -> 192GB" in the screenshot so I just wanted to confirm. [0] https://techcrunch.com/2018/05/02/digital-ocean-launches-its...
