Features

Bloomery has the following features:

• Syntax highlighting: On the web ui, the editor immediately highlights the sql keywords (e.g select, from, as, where, group, etc.) after the user types it.
• Autocomplete: While user typing any of the sql keywords, the editor’s suggestion dropdown pops up.
• Saved queries: It is possible to save any query using save query section.
• Query history: Application saves the all recent queries.
• Show query results: Shows all results under the results tab.
• Remote connection: User can change connection settings for the purpose of connecting server from different machine either with different Host IP or Port Number.
• Show tables: On top left side of the application it shows all tables of database.
• Show columns: On the bottom left side of the application it shows table columns with their type property.

Architecture

Bloomery communicates with node-impala using Express Rest API. Express Rest API maps URLs with node-impala’s connect and query methods. Then the actions like executeQuery, showTables, showColumns sends query with request parameters to Rest API then Express forwards that query to node-impala which handles and returns results using Thrift. Eventually, Express puts this results to response body which we present to users inside the table under results tab of ui menu.
