Cannot stop electrs

[ZeroQuasar]

Hi,
I'm trying out electrs but have issues gently stopping the process.
I start it with:
cargo run --release --bin electrs -- -vvvv

During the build of the txstore, or while compacting, I was trying to stop it because I was running out of diskspace. Ctrl-C does not have any effect. The only way I can stop it is by sending a SIGKILL, but I'm not sure if this has adverse effects on the database?

Side question: how much disk space does electrs need during the initial phase? It's currently in the compacting phase of the txstore (starting full compaction on RocksDB { path: ".../txstore" }) and I'm already at 1.4TB.
