It also allows you to prewarm a read replica before sending queries to it. You can also do this by slowly ramping up traffic to it (and may want to do that anyway for other reasons) but depending on the app and query patterns, that by itse

Hopefully they actually finish this at some point to be useful by showing utilization and not just quotas. For the handful of things I looked at, other than lambda which they use in their example, utilization just displays "-".

I wouldn't expect that level of disk IO to cause issues dragging existing windows around without some deeper lock contention or something, it does not behave like just IO bound. Stuff being slower, totally, but not to this level. It

Hopefully somehow maybe while they are in there they might do something to fix the nasty system lockups I have seen when starting both time machine and carbon copy cloner backups since switching to APFS. I'm assuming it is related to

An interesting postgres oddity I ran into a few years ago that isn't about counting but is in a similar arena is how under very specific circumstances, "SELECT *" is significantly faster than "SELECT one_column" des

I would guess the pricing model is actually closely related to the main dimensions of their costs and is quite valid. The key point is illustrated by this quote from their main landing page: "storage and compute are decoupled, allowing

They don't have to fully maintain it on their own. Packaging their own openjdk distribution gives them control over timely targeted bug and security fixes even if they don't have "JVM experts" working on it. I'm n

As far as I understand, Red Hat plans to take the lead on supporting a LTS version of OpenJDK 8 after Oracle steps down, with the intent to eventually do the same with 11. Various organizations such as AdoptOpenJDK will then be making rele

Are you the Mat Keep who is Director of Product Marketing at MongoDB? If so then, FWIW, people don't often respond well to marketing links posted without identifying your connection to the company.

I'm not clear what you are trying to suggest with that link. The whole point of the claim in the article around sorting is that in Aurora, for using disk to sort, postgres only has access to a relatively small filesystem that runs out

Exactly. I'd go further and say the burst capacity is actually a super useful and powerful feature that is very hard to get on your own hardware. Definitely can catch you unaware if you aren't on top of it and can get expensive

The biggest reason I've found for using a database as a queue is that you can actually run queries against it, both writes and reads. This is very useful when different entries in the queue can have some relationship that matters when

Just setting https_proxy isn't going to give you any caching benefits for https requests and isn't going to MITM TLS in any way. The client will make a CONNECT request through to the destination and the encryption is end to end a

From reading what you wrote, what I think you are talking about is statement caching where it can cache the "how do I run this" but still has to read each row (or indexed row) from the buffer cache. The mysql query cache actually

While that is true and the mysql query cache definitely became a scaling issue as machines got bigger with lock contention etc., postgres doesn't even have a similar feature period. Suppose you have a query that is doing a group by on

This has been in beta for a while, the key thing lacking for our uses, at least with postgres, was full support for DDL. The lack of "true" replication into postgres RDS instances is one of the things blocking us from fully using
