Symfony Bundle - Use file watchers with MariaDb Columnstore CpImport utility
MariaDb ColumnStore is a very powerful, column-oriented MySQL storage, powerful for analytics and Big Data.
It has the drawback of extremely slow write operations, but comes with
cpimport, a binary that can load CSV files with millions of rows into the table of your choice, in a few seconds.
This Symfony bundle enables a file watcher that will look into a directory, pick up new CSV files when they come, run
cpimport and delete them.
composer require bentools/cpimport-bundle:1.0.x-dev
Add the bundle to your kernel. Then, map your directories to database/tables like this:
# config/packages/cpimport.yaml (or app/config.yml in Symfony 3) cpimport: cpimport_bin: /usr/local/mariadb/columnstore/bin/cpimport watch: /path/to/csv_sales: database: my_shop table: sales_day options: delimiter: ',' enclosure: '"' timeout: 60
To automatically process new files in configured directories:
php bin/console cpimport:watch
To manually process a CSV file through
php bin/console cpimport:run my_shop sales_day path/to/file.csv --delimiter=','
