Druid¶

Introduced in v5.0

The Druid backend is experimental and is subject to backwards incompatible changes.

`ibis.memtable` Support ¶

The Druid backend supports memtables by constructing a string with the contents of the in-memory object. This will be very inefficient for medium to large in-memory tables. Please file an issue if you observe performance issues when using in-memory tables.

Install¶

Install ibis and dependencies for the Druid backend:

pipcondamamba

pip install 'ibis-framework[druid]'

conda install -c conda-forge ibis-druid

mamba install -c conda-forge ibis-druid

Connect¶

`ibis.druid.connect`¶

con = ibis.druid.connect(
    host="hostname",
    port=8082,
    database="druid/v2/sql",
)

ibis.druid.connect is a thin wrapper around ibis.backends.druid.Backend.do_connect.

Connection Parameters¶

`do_connect(host='localhost', port=8082, database='druid/v2/sql', **_)` ¶

Create an Ibis client using the passed connection parameters.

Parameters:

Name	Type	Description	Default
`host`	`str`	Hostname	`'localhost'`
`port`	`int`	Port	`8082`
`database`	`str \| None`	Database to connect to	`'druid/v2/sql'`

`ibis.connect` URL format¶

In addition to ibis.druid.connect, you can also connect to Druid by passing a properly formatted Druid connection URL to ibis.connect

con = ibis.connect("druid://localhost:8082/druid/v2/sql")
