# [ DEPRECATED ] PlyQL
A SQL-like interface to plywood
⛔️ This project has been deprecated due to [SQL support in Druid](http://druid.incubator.apache.org/docs/latest/querying/sql).
## Installation
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.
## Usage
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)
`--rollup` | use rollup mode [COUNT() -> SUM(count)]
`--druid-version` | Assume this is the Druid version and do not query for it
`--skip-cache` | disable Druid caching
`--introspection-strategy` | Druid introspection strategy. Use `--help` for possible values
`--force-time` | force a column to be interpreted as a time column
`--force-string` | force a column to be interpreted as a string column
`--force-boolean` | force a column to be interpreted as a boolean column
`--force-number` | force a column to be interpreted as a number column
`--force-unique` | force a column to be interpreted as a hyperLogLog uniques
`--force-theta` | force a column to be interpreted as a [theta sketch](http://druid.io/docs/latest/development/extensions-core/datasketches-aggregators.html)
`--force-histogram` | force a column to be interpreted as an approximate histogram (for quantiles)

## Roadmap
Here is a list of features that is not currently supported that are in the works:
* Query simulation - preview the queries that will be run without running them
* Sub-queries in WHERE clauses
* JOIN support
* Window functions
