Meeting 7 - November 5th, 2025
What Got Done
Created v1 of tms_min
- Built a minimal Rust server using Poem and SQLite to emulate how
tms_server interacts with SQLite
- Implemented three endpoint:
/baseline: Simple read test to see if the server is up/writeheavy: Inserts 10 rows of text into SQLite database/readheavy: Reads 10 rows of text from SQLite database
- The
/writeheavy endpoint orginally inserted 1000 rows per requests. This was reduced to 10 to try and better reflect /createkey
- Server writes to a local
tms_min.db file inside the tms_min directory
Created tms_min_loadtest
- Created another loadtest similar to
tms_loadtest, just simplified
- Ex input:
cargo run --release -- --host http://127.0.0.1:3000 --users 1000 --iterations 1000 --scenarios writeheavy

Observations
tms_min never flat out crashed- The main error I was getting was "error trying to connect: tcp open error: Too many open files (os error 24)"
Next Steps
- Keep building this and better understand the results
