Sick pg import

## Installation

Add this line to your application's Gemfile:

    gem 'vostok'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install vostok

## Usage

Vostok works directly with PG gem, no other dependencies

```ruby

require 'vostok'

# this will create an instance of `PG::Connection` inside, open it, import data and close it

import = Vostok::Import.new(dbname: 'test', user: 'developer', password: 'r00t')

data = []

1_000.times do

  data << ['String', 99]

end

import.start(:customers, [:name, :balance], data)

```

### It is also possible to use external `PG::Connection`

```ruby

connection = get_external_pg_connection()

# this will use given connection and will not try to close it

import = Vostok::Import.new(connection)

data = []

1_000.times do

  data << ['String', 99]

end

import.start(:customers, [:name, :balance], data)

```

What Vostok does not do:

1. Run validations

2. Integrates with your ORM

3. Works with databases, other than PostgreSQL

4. Sanitizes your data

However, what it does is insert rows at a sick rate.

`

10_000 rows inserted with AR - 18 seconds

`

`

10_000 rows inserted with Vostok - 0.2 seconds
