I've done a bit of work on this in my free time. I put together a rough [ANSI parser in Go](https://github.com/aoldershaw/ansi) in an effort to mirror https://github.com/vito/elm-ansi (that we use...

Oh, it's also worth noting that even with server-side processing of the ANSI control sequences, rendering the log lines is still very slow. It may be worth implementing an infinite...

As I suspected, changing the build events endpoint to send one event of formatted log lines per event of unformatted log data hinders performance compared to sending one large event....

I wonder if an approach like a) or c) could be made more general - rather than always writing to the necessarily writing the formatted logs to the database, we...

Trying to do some benchmarks to the performance bottleneck of processing the log events (in terms of actual computation time). Running on a fairly small build (https://ci.concourse-ci.org/teams/main/pipelines/release-5.5.x/jobs/k8s-topgun/builds/47) with only ~150...

I'd take a look at https://github.com/concourse/concourse/issues/3879 which discusses some approaches. We will probably have to stop storing logs as build events and start interpreting them and storing them by line...

hey, I'm not too familiar with OCI hooks/what they are for. were you using OCI hooks with Guardian somehow? do mind sharing a bit of your use case?

Got it, thanks for the information! could you shed some light on this custom gdn instance? Is it possible to do something similar with the packaged gdn? Recent versions of...

Do you have statistics enabled on your Postgres instance? Can you try running some of these queries to get a sense of where the bottleneck is: https://github.com/concourse/concourse/wiki/Schema-Inspection-Queries#show-in-flight-queries

@robwhitby thanks for providing query insights. We too are seeing that query to be periodically very slow on our (fairly) large deployment. Our query insights dashboard (also GCP) tells us...
