ITERATIONS=5000

create_drop_worker() {
    for i in $(seq 1 $ITERATIONS); do
        redis-cli -h $HOST -p $PORT FT.CREATE $INDEX ON HASH PREFIX 1 doc: SCHEMA title TEXT 2>/dev/null
        redis-cli -h $HOST -p $PORT FT.DROPINDEX $INDEX 2>/dev/null
    done
}

info_worker() {
    for i in $(seq 1 $ITERATIONS); do
        redis-cli -h $HOST -p $PORT FT.INFO $INDEX 2>/dev/null
    done
}

for i in {1..5}; do
    create_drop_worker &
    info_worker &
done
