It does not. You can use something like Avo to lighten the load a bit of writing those assembly routines. It takes care of register allocation, struct fields, and the necessary function stubs.

This is about reducing the number of message delays before the commit succeeds. Failure scenarios have to be handled to be correct, but this is a performance optimization primarily from what I can see.

Are you using AWS Lambda to provide the sandboxing? If so: How does the user code actually end up running on the Lambda? Do you have a generic wrapper Lambda which `eval`s the user code, or do you deploy an individual Lambda for each functi

How confident are you that your database abstraction is going to fulfill the needs of someone with anything more than a few trivial query workloads? I didn't hear much about the database at all other than "it just works." Thi

Yes, it is more similar to Hyder than FoundationDB if you persist the R/W sets to the log itself. FoundationDB gets around this by only keeping the lock table in memory. When any process in the transaction pipeline fails, the master (w

This design can be extended to support interactive transactions. Here's how: 1. Assign each transaction a log position. For strict serializability instead of just serializability, make this the highest log position ever acknowledged su

Is it fair to say that if you know the min and max values for your dataset, the DDSketch (fast) is strictly better than HDR Histogram for applications where lack of runtime memory allocations and add performance is critical?

BigQuery and Snowflake are the two managed services I'd recommend today if you'd like good performance and cost-effective storage. They both separate compute from storage so that your cold data isn't sitting on expensive SSDs

That's probably a good idea to get to a usable product. You may want to investigate a proper data warehouse if your workload primarily consists of large scans and aggregations, such as if you offer a user-facing dashboard which can gen

Have you done any analysis of your per-core scan rates for simple aggregations like sum/count + group by with a reasonably large cardinality key? Or has anyone published a benchmark you trust on queries of that variety? An example woul

Are you afraid the Postgres tuple-at-a-time iterator architecture is going to be limiting for your long term performance optimizations? Presumably the custom operators you’ve implemented in your query plan can push projection and predicates

Another useful unsafe slice operation is casting a byte slice to a string so you can e.g. use it as a map key. Watch your lifetimes though! You probably also wouldn’t want to use any string manipulation functions on it, but I’ve never had a
