Add benchmark for DuckDB
2021-10-31 18:05:07 +00:00
Export data from ClickHouse:
```
SELECT * FROM hits_100m_obfuscated INTO OUTFILE 'hits.parquet' FORMAT Parquet
$ wc -c hits.parquet
17193559098 hits.parquet
```
Install DuckDB:
```
wget https://github.com/duckdb/duckdb/releases/download/v0.3.0/duckdb_cli-linux-amd64.zip
unzip duckdb_cli-linux-amd64.zip
```
Try DuckDB:
```
milovidov@mtlog-perftest03j:~$ ./duckdb
v0.3.0 46a0fc50a
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.

Let's load the data:
```
D CREATE TABLE hits AS SELECT * FROM parquet_scan('hits.parquet')
> ;
```
It is using single CPU core and accumulating data in memory.
```
Killed
```
As expected. My server has "only" 128 GiB RAM.
Let's free some memory and run again:
```
Error: Out of Memory Error: could not allocate block of 262144 bytes
Database is launched in in-memory mode and no temporary directory is specified.
Unused blocks cannot be offloaded to disk.
Launch the database with a persistent storage back-end
Or set PRAGMA temp_directory='/path/to/tmp.tmp'
```
Now it works:
```
D PRAGMA temp_directory='duckdb.tmp'
> ;
D CREATE TABLE hits AS SELECT * FROM parquet_scan('hits.parquet');
D SELECT count(*) FROM hits;

But saving the database does not work:
```
D .save 'duckdb.data'
sqlite3_backup_init: unsupported.
Error:

Let's simply paste queries into CLI.

Mostly alright but some functions are missing and the types from Parquet are wrong.
Let's try to load from CSV:
```
SELECT * FROM hits_100m_obfuscated INTO OUTFILE 'hits.csv' FORMAT CSV
```
```
$ ./duckdb
v0.3.0 46a0fc50a
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.

Error: String value is not valid UTF8

It does not work for non-UTF8 data.
Let's cleanup UTF-8.
```
clickhouse-local --input-format LineAsString --output-format TSVRaw --structure 's String' --query "SELECT toValidUTF8(s) FROM table" --progress < hits.csv > hits_valid.csv
```
```
D CREATE TABLE hits AS SELECT * FROM read_csv_auto('hits_valid.csv');
Error: Invalid Input Error: Could not convert string '2149615427' to INT32 in column "column082", between line 137217 and 138240.

```
Does not work either.
DuckDB CLI does not support history search (Ctrl+R).
If I write a command and then prepend `-- ` before it, then history navigation becomes completely broken.
```
D CREATE TABLE hits AS SELECT * FROM parquet_scan('hits.parquet' ;
Run Time: real 0.000 user 0.000000 sys 0.000000
Error: Parser Error: syntax error at or near ";"

```
D CREATE TABLE hits AS SELECT * FROM parquet_scan('hits.parquet');
Run Time: real 1086.631 user 758.036000 sys 201.360000
```
It's just about 100 000 rows/second. Quite decent but not good.
Cancelling queries by Ctrl+C does not work.
I've noticed that DuckDB is using single thread.
Most likely it can be fixed with
```
PRAGMA threads = 16;
```
```
PRAGMA threads = 16;
PRAGMA temp_directory='duckdb.tmp';
.timer on
CREATE TABLE hits AS SELECT * FROM parquet_scan('hits.parquet');
```
It's much better with threads:
```
D CREATE TABLE hits AS SELECT * FROM parquet_scan('hits.parquet');
Run Time: real 315.828 user 447.896000 sys 126.552000
```
Let's run all the queries three times.
Collecting the results:
```
grep -F 'Run Time: real ' log | grep -oP 'real [\d\.]+' | grep -oP '[\d\.]+' | tail -n129 | clickhouse-local --structure 'x Decimal32(3)' --query "SELECT groupArray(x) FROM table GROUP BY rowNumberInAllBlocks() % 43 AS n ORDER BY n"
```
Let's create index to speed up point queries:
```
D CREATE INDEX counter_id_idx ON hits (CounterID);
Run Time: real 18.194 user 16.256000 sys 0.092000
```
Ok, it's quite fast.
Rerun the last 7 queries.
