A SQL-like interface to plywood

⛔️ This project has been deprecated due to SQL support in Druid.


PlyQL is built on top of node so make sure you have node >= 4.x.x installed.

npm install -g plyql

The global install will make the plyql command available system wide.


Currently only queries to Druid are supported. More support will come in the future.

The CLI supports the following options:

Option Description
--help print this help message
--version display the version number
-v, --verbose display the queries that are being made
-h, --host the host to connect to
-s, --source use this source for the query (supersedes FROM clause)
-i, --interval add (AND) a __time filter between NOW-INTERVAL and NOW
-tz, --timezone the default timezone
-q, --query the query to run
-o, --output specify the output format. Possible values: json (default), csv, tsv, flat
-a, --allow enable a behaviour that is turned off by default eternity allow queries not filtered on time select allow select queries
-t, --timeout the time before a query is timed out in ms (default: 60000)
-r, --retry the number of tries a query should be attempted on error, 0 = unlimited, (default: 2)
-c, --concurrent the limit of concurrent queries that could be made simultaneously, 0 = unlimited, (default: 2)
