|
||
|
||
在控制台运行以下命令：
|
||
|
||
```bash
|
||
sudo apt-get install s3cmd
|
||
mkdir tiny; cd tiny;
|
||
s3cmd sync s3://big-data-benchmark/pavlo/text-deflate/tiny/ .
|
||
cd ..
|
||
mkdir 1node; cd 1node;
|
||
s3cmd sync s3://big-data-benchmark/pavlo/text-deflate/1node/ .
|
||
cd ..
|
||
mkdir 5nodes; cd 5nodes;
|
||
s3cmd sync s3://big-data-benchmark/pavlo/text-deflate/5nodes/ .
|
||
cd ..
|
||
```
|
||
|
||
在ClickHouse运行如下查询：
|
||
|
||
``` sql
|
||
CREATE TABLE rankings_tiny
|
||
(
|
||
pageURL String,
|
||
pageRank UInt32,
|
||
avgDuration UInt32
|
||
) ENGINE = Log;
|
||
|
||
CREATE TABLE uservisits_tiny
|
||
(
|
||
sourceIP String,
|
||
destinationURL String,
|
||
visitDate Date,
|
||
adRevenue Float32,
|
||
UserAgent String,
|
||
cCode FixedString(3),
|
||
lCode FixedString(6),
|
||
searchWord String,
|
||
duration UInt32
|
||
) ENGINE = MergeTree(visitDate, visitDate, 8192);
|
||
|
||
CREATE TABLE rankings_1node
|
||
(
|
||
pageURL String,
|
||
pageRank UInt32,
|
||
avgDuration UInt32
|
||
) ENGINE = Log;
|
||
|
||
CREATE TABLE uservisits_1node
|
||
(
|
||
sourceIP String,
|
||
destinationURL String,
|
||
visitDate Date,
|
||
adRevenue Float32,
|
||
UserAgent String,
|
||
cCode FixedString(3),
|
||
lCode FixedString(6),
|
||
searchWord String,
|
||
duration UInt32
|
||
) ENGINE = MergeTree(visitDate, visitDate, 8192);
|
||
|
||
CREATE TABLE rankings_5nodes_on_single
|
||
(
|
||
pageURL String,
|
||
pageRank UInt32,
|
||
avgDuration UInt32
|
||
) ENGINE = Log;
|
||
|
||
CREATE TABLE uservisits_5nodes_on_single
|
||
(
|
||
sourceIP String,
|
||
destinationURL String,
|
||
visitDate Date,
|
||
adRevenue Float32,
|
||
UserAgent String,
|
||
cCode FixedString(3),
|
||
lCode FixedString(6),
|
||
searchWord String,
|
||
duration UInt32
|
||
) ENGINE = MergeTree(visitDate, visitDate, 8192);
|
||
```
|
||
|
||
回到控制台运行如下命令：
|
||
|
||
```bash
|
||
for i in tiny/rankings/*.deflate; do echo $i; zlib-flate -uncompress < $i | clickhouse-client --host=example-perftest01j --query="INSERT INTO rankings_tiny FORMAT CSV"; done
|
||
for i in tiny/uservisits/*.deflate; do echo $i; zlib-flate -uncompress < $i | clickhouse-client --host=example-perftest01j --query="INSERT INTO uservisits_tiny FORMAT CSV"; done
|
||
for i in 1node/rankings/*.deflate; do echo $i; zlib-flate -uncompress < $i | clickhouse-client --host=example-perftest01j --query="INSERT INTO rankings_1node FORMAT CSV"; done
|
||
for i in 1node/uservisits/*.deflate; do echo $i; zlib-flate -uncompress < $i | clickhouse-client --host=example-perftest01j --query="INSERT INTO uservisits_1node FORMAT CSV"; done
|
||
for i in 5nodes/rankings/*.deflate; do echo $i; zlib-flate -uncompress < $i | clickhouse-client --host=example-perftest01j --query="INSERT INTO rankings_5nodes_on_single FORMAT CSV"; done
|
||
for i in 5nodes/uservisits/*.deflate; do echo $i; zlib-flate -uncompress < $i | clickhouse-client --host=example-perftest01j --query="INSERT INTO uservisits_5nodes_on_single FORMAT CSV"; done
|
||
```
|
||
|
||
简单的查询示例：
|
||
|
||
``` sql
|
||
SELECT pageURL, pageRank FROM rankings_1node WHERE pageRank > 1000
|
||
|
||
SELECT substring(sourceIP, 1, 8), sum(adRevenue) FROM uservisits_1node GROUP BY substring(sourceIP, 1, 8)
|
||
|
||
SELECT
|
||
sourceIP,
|
||
sum(adRevenue) AS totalRevenue,
|
||
avg(pageRank) AS pageRank
|
||
FROM rankings_1node ALL INNER JOIN
|
||
(
|
||
SELECT
|
||
sourceIP,
|
||
destinationURL AS pageURL,
|
||
adRevenue
|
||
FROM uservisits_1node
|
||
WHERE (visitDate > '1980-01-01') AND (visitDate < '1980-04-01')
|
||
) USING pageURL
|
||
GROUP BY sourceIP
|
||
ORDER BY totalRevenue DESC
|
||
LIMIT 1
|
||
```
