# kiba-plus
Kiba enhancement for Ruby ETL. It connects to various data sources including relational, non-relational, and flat file, cloud services and HTTP resources. It has flexible load strategies including insert, bulk load and upsert.
# Usage
```ruby
# /tmp/customer_mysql_to_pg.etl
require 'kiba/plus'
require 'kiba/plus/source/mysql'
require 'kiba/plus/destination/pg_bulk2'
SOURCE_URL = 'mysql://root@localhost/shopperplus'
DEST_URL = 'postgresql://hooopo@localhost:5432/crm2_dev'
source Kiba::Plus::Source::Mysql, { :connect_url => SOURCE_URL,
:query => %Q{SELECT id, email, 'hooopo' AS first_name, 'Wang' AS last_name FROM customers}
}
destination Kiba::Plus::Destination::PgBulk2, { :connect_url => DEST_URL,
:table_name => "customers",
:truncate => true,
:columns => [:id, :email, :first_name, :last_name],
:incremental => false
}
post_process do
result = PG.connect(DEST_URL).query("SELECT COUNT(*) AS num FROM customers")
puts "Insert total: #{result.first['num']}"
end
```
Execute in shell:
```shell
$ bundle exec kiba /tmp/customer_mysql_to_pg.etl
# Output:
# I, [2016-05-16T01:53:36.832565 #87909] INFO -- : TRUNCATE TABLE customers;
# I, [2016-05-16T01:53:36.841770 #87909] INFO -- : COPY customers (id, email, first_name, last_name) FROM STDIN WITH DELIMITER ',' NULL '\N' CSV
# Insert total: 428972
```
Execute in ruby script:
```ruby
require 'kiba'
job_definition = Kiba.parse(IO.read('/tmp/customer_mysql_to_pg.etl'), '/tmp/customer_mysql_to_pg.etl')
Kiba.run(job_definition)
```

## Installation
Add this line to your application's Gemfile:
```ruby
gem 'kiba'
gem 'kiba-plus'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install kiba-plus
## Development
First of all, Please run the following code in shell.
```bash
$ mysql -e 'create database kiba_plus_src_test;'
$ mysql -e 'create database kiba_plus_dest_test;'
$ psql -c 'create database kiba_plus_src_test;' -U postgres
$ psql -c 'create database kiba_plus_dest_test;' -U postgres
```
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
