DevX in Rust for backend development is quite good nowadays. Things are WAY easier than it was a couple of years ago. I migrated a couple of projects from Java, TS and Go to Rust and honesly, I couldn't be happier.

Same here. But have you tried duckdb? You can do sql in the pandas dfs and it is fast af. https://duckdb.org/2021/05/14/sql-on-pandas.html

This looks really nice. I was reading about this and realized it had similar ideas to this [1] Phd thesis from Jon Gjengset. I checked his twitter [2] and it was based on his work indeed. Great that someone is productionalizing this! Btw, i

Depending on the cost per database, a service like this could allow one to build SAAS apps with Single Tenant model [1] in a really simple and elegant way. I always liked this model since it gives the best isolation and not having to code w

Dan Luu impact at Wave.com is noticable already. Since he joined in March, Wave is pushing one great blog post per week (in contrast to 1 in 2021, 0 in 2020 and 3 in 2019). I tried creating this culture of blogging but failed, would love to

wow.... this is amazing! I dindn't get this: `OrioleDB implements default 64-bit transaction identifiers, thus eliminating the well-known and painful wraparound problem` I thought that PG's 32-bit transaction identifier and wrapar

This is really nice! Congrats! I once started building as a side project something similar but focused on querying cloud resources (like S3 buckets, ec2s, etc... discovering the biggest file from a bucket was trivial with this). I abandoned

That is pretty landing page! Just read that the meaning of oku [1] is 1) private, intimate, and deep; 2) exalted and sacred; and, 3) profound and recondite anyway, your brazilian users will find this funny since oku has the same sound of &q

They mention this in the article. But to sum up, each connection in PG is handled by its own OS process. Postgres behind the scenes is composed by multiple single-threaded applications. This comes with the advantes for Pg developers (and us

Comparing Fauna with DynamoDB and Redis gives the wrong impression. Trade-offs are totally different. However, the product in question (Upstash), looks very interesting: serverless storage with a pay as you go model with a maximum price cap

Apache Drill is an interesting project, from all the MPP engines that appeared a few years ago, it was the most similar one to BigQuery (the first public version) and the most flexible. However, the competion was fierce and each Big Data ve

I don't believe grafana will help you here. If you have mongodb enterprise you can use Mongo bi connector and connect it with any bi tool. I recommend metabase since it is open source and very good for slice and dice and reports. The m

This is an SDK not a full client for Kinesis. This is the only official implementation from AWS: https://github.com/awslabs/amazon-kinesis-client The client handles horizontal scalling, checkpoiting, shards split and s

Because the official client from AWS is written in Java. It is possible to write clients in any language, however, it is not that simple especially when you need to handle logic of scalling out or in your kinesis stream (that will split or

I believe you will enjoy this: https://medium.com/revolut/recording-more-events-but-where-w... Not exactly the same architecture you are proposing, and quite complex tbh, but it is working for them.

I don't know about aurora serverless. But aws offers a proxy exactly for this purpose. https://aws.amazon.com/rds/proxy/

by agacera 6y ago
Aurora is indeed amazing. However, my experience with it regarding costs is that main cost you have running it is not compute, but IO ($0.2 per million requets [1]). This cost is kind of hidden since to estimate this in the early stages of

Can you please elaborate a little bit more of how you replaced it by postgres? Because it is strange that a single box of postgres in way less powerful instance type would perform the same as your cassandra cluster. This kind of seems that

yes it is, as long as you can represent it in SQL. for instance, for a query like: select day_of_year, year, count(*) from orders where year >= 2016 group by day_of_year, year you can create a line visualization that will display the dif

I think it depends of the organization. Most companies still use something similar to a DW/DL that speaks SQL, so Metabase/Redash still cover this. Tableau is awesome, but I believe that most of its features are not used soo often

What do you mean by reports? If by reports you mean a daily email sent with a table and some graphs attached them both suck. The only tool that I know that excels on this is Reporting Services from Microsoft. But they are really OK for dash
