clickhouse benchmark
Usage: clickhouse benchmark [options] < queries.txt
Usage: clickhouse benchmark [options] --query "query text"
clickhouse-benchmark connects to ClickHouse server, repeatedly sends specified queries and produces reports query statistics.
clickhouse client
Usage: clickhouse client [initial table definition] [--query <query>]
clickhouse-client is a client application that is used to connect to ClickHouse.
It can run queries as command line tool if you pass queries as an argument or as interactive client. Queries can run one at a time, or in in a multiquery mode with --multiquery option. To change settings you may use 'SET' statements and SETTINGS clause in queries or set is for a session with corresponding clickhouse-client arguments.
'clickhouse client' command will try connect to clickhouse-server running on the same server. If you have credentials set up pass them with --user <username> --password <password> or with --ask-password argument that will open command prompt.
This one will try connect to tcp native port(9000) without encryption:
clickhouse client --host clickhouse.example.com --password mysecretpassword
To connect to secure endpoint just set --secure argument. If you have artered port set it with --port <your port>.
clickhouse client --secure --host clickhouse.example.com --password mysecretpassword
clickhouse local
Usage: clickhouse local [initial table definition] [--query <query>]
clickhouse-local allows to execute SQL queries on your data files without running clickhouse-server.
It can run as command line tool that does single action or as interactive client. For interactive experience you can just run 'clickhouse local' or add --interactive argument to your command. It will set up tables, run queries and pass control as if it is clickhouse-client. Then you can execute your SQL queries in usual manner. Non-interactive mode requires query as an argument and exits when queries finish. Multiple SQL queries can be passed as --query argument.
To configure initial environment two ways are supported: queries or command line parameters. Either just in first query like this:
CREATE TABLE <table> (<structure>) ENGINE = File(<input-format>, <file>);
Or through corresponding command line parameters --table --structure --input-format and --file.
clickhouse-local supports all features and engines of ClickHouse. You can query data from remote engines and store results locally or other way around. For table engines that actually store data on a disk like Log and MergeTree clickhouse-local puts data to temporary directory that is not reused between runs.
clickhouse-local can be used to query data from stopped clickhouse-server installation with --path to local directory with data.
Example reading file from S3, converting format and writing to a file:
clickhouse-local --query "SELECT c1 as version, c2 as date FROM url('https://raw.githubusercontent.com/ClickHouse/ClickHouse/master/utils/list-versions/version_date.tsv') INTO OUTFILE '/tmp/versions.json'"
clickhouse compressor

--log-level arg (=error) log level
-c [ --config-file ] arg path to config file
-k [ --key ] arg key to get value for
clickhouse format
Usage: clickhouse format [options] < query
clickhouse git-import
A tool to extract information from Git repository for analytics.
It dumps the data for the following tables:
- commits - commits with statistics;
- file_changes - files changed in every commit with the info about the change and statistics;
- line_changes - every changed line in every changed file in every commit with full info about the line and the information about previous change of this line.
The largest and the most important table is "line_changes".
Allows to answer questions like:
- list files with maximum number of authors;
- show me the oldest lines of code in the repository;
- show me the files with longest history;
- list favorite files for author;
- list largest files with lowest number of authors;
- at what weekday the code has highest chance to stay in repository;
- the distribution of code age across repository;
- files sorted by average code age;
- quickly show file with blame info (rough);
- commits and lines of code distribution by time; by weekday, by author; for specific subdirectories;

The data is intended for analytical purposes. It can be imprecise by many reasons but it should be good enough for its purpose.
The data is not intended to provide any conclusions for managers, it is especially counter-indicative for any kinds of "performance review". Instead you can spend multiple days looking at various interesting statistics.
Run this tool inside your git repository. It will create .tsv files that can be loaded into ClickHouse (or into other DBMS if you dare).
The tool can process large enough repositories in a reasonable time.
It has been tested on:
- ClickHouse: 31 seconds; 3 million rows;
- LLVM: 8 minutes; 62 million rows;
- Linux - 12 minutes; 85 million rows;
- Chromium - 67 minutes; 343 million rows;
(the numbers as of Sep 2020)

clickhouse obfuscator
Simple tool for table data obfuscation.
It reads input table and produces output table, that retain some properties of input, but contains different data.
It allows to publish almost real production data for usage in benchmarks.
It is designed to retain the following properties of data:
- cardinalities of values (number of distinct values) for every column and for every tuple of columns;
- conditional cardinalities: number of distinct values of one column under condition on value of another column;
- probability distributions of absolute value of integers; sign of signed integers; exponent and sign for floats;
- probability distributions of length of strings;
- probability of zero values of numbers; empty strings and arrays, NULLs;
- data compression ratio when compressed with LZ77 and entropy family of codecs;
- continuity (magnitude of difference) of time values across table; continuity of floating point values.
- date component of DateTime values;
- UTF-8 validity of string values;
- string values continue to look somewhat natural.
Most of the properties above are viable for performance testing:
- reading data, filtering, aggregation and sorting will work at almost the same speed
as on original data due to saved cardinalities, magnitudes, compression ratios, etc.
It works in deterministic fashion: you define a seed value and transform is totally determined by input data and by seed.
Some transforms are one to one and could be reversed, so you need to have large enough seed and keep it in secret.
It use some cryptographic primitives to transform data, but from the cryptographic point of view,
it doesn't do anything properly and you should never consider the result as secure, unless you have other reasons for it.
It may retain some data you don't want to publish.
It always leave numbers 0, 1, -1 as is. Also it leaves dates, lengths of arrays and null flags exactly as in source data.
For example, you have a column IsMobile in your table with values 0 and 1. In transformed data, it will have the same value.
So, the user will be able to count exact ratio of mobile traffic.
Another example, suppose you have some private data in your table, like user email and you don't want to publish any single email address.
If your table is large enough and contain multiple different emails and there is no email that have very high frequency than all others,
it will perfectly anonymize all data. But if you have small amount of different values in a column, it can possibly reproduce some of them.
And you should take care and look at exact algorithm, how this tool works, and probably fine tune some of it command line parameters.
This tool works fine only with reasonable amount of data (at least 1000s of rows).
Usage: clickhouse obfuscator [options] < in > out
Input must be seekable file (it will be read twice).
Example:
clickhouse obfuscator --seed "$(head -c16 /dev/urandom | base64)" --input-format TSV --output-format TSV --structure 'CounterID UInt32, URLDomain String, URL String, SearchPhrase String, Title String' < stats.tsv

clickhouse-local
Usage: clickhouse local [initial table definition] [--query <query>]
clickhouse-local allows to execute SQL queries on your data files without running clickhouse-server.
It can run as command line tool that does single action or as interactive client. For interactive experience you can just run 'clickhouse local' or add --interactive argument to your command. It will set up tables, run queries and pass control as if it is clickhouse-client. Then you can execute your SQL queries in usual manner. Non-interactive mode requires query as an argument and exits when queries finish. Multiple SQL queries can be passed as --query argument.
To configure initial environment two ways are supported: queries or command line parameters. Either just in first query like this:
CREATE TABLE <table> (<structure>) ENGINE = File(<input-format>, <file>);
Or through corresponding command line parameters --table --structure --input-format and --file.
clickhouse-local supports all features and engines of ClickHouse. You can query data from remote engines and store results locally or other way around. For table engines that actually store data on a disk like Log and MergeTree clickhouse-local puts data to temporary directory that is not reused between runs.
clickhouse-local can be used to query data from stopped clickhouse-server installation with --path to local directory with data.
Example reading file from S3, converting format and writing to a file:
clickhouse-local --query "SELECT c1 as version, c2 as date FROM url('https://raw.githubusercontent.com/ClickHouse/ClickHouse/master/utils/list-versions/version_date.tsv') INTO OUTFILE '/tmp/versions.json'"
clickhouse-client
Usage: clickhouse client [initial table definition] [--query <query>]
clickhouse-client is a client application that is used to connect to ClickHouse.
It can run queries as command line tool if you pass queries as an argument or as interactive client. Queries can run one at a time, or in in a multiquery mode with --multiquery option. To change settings you may use 'SET' statements and SETTINGS clause in queries or set is for a session with corresponding clickhouse-client arguments.
'clickhouse client' command will try connect to clickhouse-server running on the same server. If you have credentials set up pass them with --user <username> --password <password> or with --ask-password argument that will open command prompt.
This one will try connect to tcp native port(9000) without encryption:
clickhouse client --host clickhouse.example.com --password mysecretpassword
To connect to secure endpoint just set --secure argument. If you have artered port set it with --port <your port>.
clickhouse client --secure --host clickhouse.example.com --password mysecretpassword
clickhouse-benchmark
Usage: clickhouse benchmark [options] < queries.txt
Usage: clickhouse benchmark [options] --query "query text"
clickhouse-benchmark connects to ClickHouse server, repeatedly sends specified queries and produces reports query statistics.
clickhouse-extract
Preprocess config file and extract value of the given key.
Usage: clickhouse extract-from-config [options]
clickhouse-compressor
Usage: clickhouse compressor [options] < INPUT > OUTPUT
Alternative usage: clickhouse compressor [options] INPUT OUTPUT
clickhouse-format
Usage: clickhouse format [options] < query

clickhouse-git-import
A tool to extract information from Git repository for analytics.
It dumps the data for the following tables:
- commits - commits with statistics;
- file_changes - files changed in every commit with the info about the change and statistics;
- line_changes - every changed line in every changed file in every commit with full info about the line and the information about previous change of this line.
The largest and the most important table is "line_changes".
Allows to answer questions like:
- list files with maximum number of authors;
- show me the oldest lines of code in the repository;
- show me the files with longest history;
- list favorite files for author;
- list largest files with lowest number of authors;
- at what weekday the code has highest chance to stay in repository;
- the distribution of code age across repository;
- files sorted by average code age;
- quickly show file with blame info (rough);
- commits and lines of code distribution by time; by weekday, by author; for specific subdirectories;
- show history for every subdirectory, file, line of file, the number of changes (lines and commits) across time; how the number of contributors was changed across time;
- list files with most modifications;
- list files that were rewritten most number of time or by most of authors;
- what is percentage of code removal by other authors, across authors;
- the matrix of authors that shows what authors tends to rewrite another authors code;
- what is the worst time to write code in sense that the code has highest chance to be rewritten;
- the average time before code will be rewritten and the median (half-life of code decay);
- comments/code percentage change in time / by author / by location;
- who tend to write more tests / cpp code / comments.
The data is intended for analytical purposes. It can be imprecise by many reasons but it should be good enough for its purpose.
