A queue and an event stream are not the same thing
One distributes work and forgets it. The other is an ordered log several consumers can replay. Choosing the wrong one produces an architecture that fights you for years.
Tuning managed PostgreSQL, where you do not control the machine
Nearly every performance incident we investigate is a missing index, a connection pool that is not there, or autovacuum sized for a database a tenth the size. Resizing the instance is the fix people try first and it is almost never the answer.
Choosing an analytics platform by the constraint that binds
Open table formats changed the negotiation by separating storage from compute. What is left to decide is your workload mix, your governance boundary, and which cost model you can actually control.
The cache that fixes your latency and creates three new problems
Invalidation, stampede and the day the cache fills are the three. A time to live is the boring correct answer to the first, and most caching problems turn out to be a missing index.
