Test Cases

Disable Fuse Cache, databend-query.toml:

table_cache_enabled = false

Disable Data Cache:

export STORAGE_CACHE_TYPE=none

Case1: Using local disk as data cache backend

Enable local disk data cache:

export STORAGE_CACHE_TYPE=fs
export STORAGE_CACHE_FS_DATA_PATH=/root/databend/cache_data

Query	No Data Cache	Data Cache	Fuse Cache+No Data Cache	Fuse Cache + Data Cache
Q3: SELECT SUM(AdvEngineID), COUNT(*), AVG(ResolutionWidth) FROM hits	1.23 sec	0.61 sec	0.17 sec	0.13 sec
Q4: SELECT AVG(UserID) FROM hits	1.30 sec	0.65 sec	0.32 sec	0.17 sec
Q5: SELECT COUNT(DISTINCT UserID) FROM hits	4.6 sec	4.22 sec	3.73 sec	3.73 sec
Q22	5.76 sec	4.01 sec	3.79 sec	3.57 sec

Case2: Using moka(Memory) as data cache backend

Enable memory data cache:

export STORAGE_CACHE_TYPE=moka
# 4GiB, larger than the query data.
export STORAGE_CACHE_MOKA_MAX_CAPACITY=4294967296

Query	No Data Cache	Data Cache	Fuse Cache+No Data Cache	Fuse Cache + Data Cache
Q3: SELECT SUM(AdvEngineID), COUNT(*), AVG(ResolutionWidth) FROM hits	1.23 sec	0.65 sec	0.17 sec	0.12 sec
Q4: SELECT AVG(UserID) FROM hits	1.30 sec	0.52 sec	0.32 sec	0.12 sec
Q5: SELECT COUNT(DISTINCT UserID) FROM hits	4.6 sec	4.12 sec	3.73 sec	3.60 sec
Q22	5.76 sec	3.29 sec	3.79 sec	2.81 sec

Snowflake (Small)

Disable the query result cache:

ALTER SESSION SET USE_CACHED_RESULT=FALSE;

Update:
Add Snowflake test with cache.

[BohuTANG]

Bench all [hits queries](https://github.com/ClickHouse/ClickBench/blob/main/databend/queries.sql).
Cluster:

databend-meta: 192.168.0.1
databend-query: 192.168.0.2
redis: 192.168.0.2

run.sh

#!/bin/bash

TRIES=3
QUERY_NUM=1
cat queries.sql | while read query; do
    sync
    echo 3 | sudo tee /proc/sys/vm/drop_caches >/dev/null

    echo -n "q${QUERY_NUM}["
    for i in $(seq 1 $TRIES); do
        RES=$(curl -w 'Time: %{time_total}\n' http://default@localhost:8124?database=hits -d "${query}" 2>&1 | grep -P '^Time: ' | sed 's/Time: //')
        [[ "$?" == "0" ]] && echo -n "${RES}" || echo -n "null"
        [[ "$i" != $TRIES ]] && echo -n ", "

        echo "${QUERY_NUM},${i},${RES}" >> result.csv
    done
    echo "],"

    QUERY_NUM=$((QUERY_NUM + 1))
done

Each query run 3 times[cold(may warm, we don't clean the cache for each query), hot, hot]
