NAME

ClickHouse - Database driver for Clickhouse OLAP Database

VERSION

Version 0.05

SYNOPSIS

ClickHouse - perl interface to Clickhouse Database. My final goal is to create DBI compatible driver for ClickHouse, but for now it's standalone module.

It's the first version and so module is EXPERIMENTAL. I can't guarantee API stability. More over, API will probably change and it will be soon.

This module is a big rough on the edges, but I decided to release it on CPAN so people can start playing around with it.

EXAMPLE

    use ClickHouse;

    my $ch = ClickHouse->new(
        host     => $ENV{'CLICK_HOUSE_HOST'}
        port     => 8123,
        user     => 'Frodo'
        password => 'finger',
        timeout  => 5,
    );

    my $rows = $ch->select("SELECT id, field_one, field_two FROM some_table");

    for my $row (@$rows) {
        # Do something with your row
    }

    $ch->do("INSERT INTO some_table (id, field_one, field_two) VALUES",
        [1, "String value", 38962986],
        [2, "String value", 38962986],
    );

SUBROUTINES/METHODS

new

Create new connection object

select

Fetch data from table. It returns a reference to an array that contains one reference per row (similar to DBI::fetchall_arrayref).

do

Modify data inside the database. It's universal method for any queries, which modify data. So if you want to create, alter, detach or drop table or partition or insert data into table it's your guy.
