Installation
|
|
------------
|
|
``sprockets-postgres`` is available on the Python package index and is installable via pip:
|
|
|
|
.. code:: bash
|
|
|
|
pip install sprockets-postgres
|
|
|
|
Documentation
|
|
-------------
|
|
Documentation is available at `sprockets-postgres.readthedocs.io <https://sprockets-postgres.readthedocs.io>`_.
|
|
|
|
Configuration
|
|
-------------
|
|
Configuration of sprockets-postgres is done by using of environment variables or
|
|
`tornado.web.Application.settings <https://www.tornadoweb.org/en/stable/web.html#tornado.web.Application.settings>`_
|
|
dictionary. The `sprockets_postgres.ApplicationMixin <https://sprockets-postgres.readthedocs.io/en/stable/application.html>`_
|
|
will use configuration as applied to the settings dictionary, falling back to the
|
|
environment variable if the value is not set in the dictionary. Keys in the
|
|
settings dictionary are lowercase, and if provided as environment variables,
|
|
are uppercase.
|
|
|
|
The following table details the available configuration options:
|
|
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| Variable | Definition | Type | Default |
|
|
+=================================+==================================================+======+===========+
|
|
| ``postgres_url`` | The PostgreSQL URL to connect to | str | |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_max_pool_size`` | Maximum connection count to Postgres per backend | int | ``10`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_min_pool_size`` | Minimum or starting pool size. | int | ``1`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_connection_timeout`` | The maximum time in seconds to spend attempting | int | ``10`` |
|
|
| | to create a new connection. | | |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_connection_ttl`` | Time-to-life in seconds for a pooled connection. | int | ``300`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_query_timeout`` | Maximum execution time for a query in seconds. | int | ``60`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_hstore`` | Enable HSTORE support in the client. | bool | ``FALSE`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_json`` | Enable JSON support in the client. | bool | ``FALSE`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
| ``postgres_uuid`` | Enable UUID support in the client. | bool | ``TRUE`` |
|
|
+---------------------------------+--------------------------------------------------+------+-----------+
|
|
|
|
If ``postgres_url`` uses a scheme of ``postgresql+srv``, a SRV DNS lookup will be
|
|
performed and the lowest priority record with the highest weight will be selected
|
|
for connecting to Postgres.
|
|
|
|
AWS's ECS service discovery does not follow the SRV standard, but creates SRV
|
|
records. If ``postgres_url`` uses a scheme of ``aws+srv``, a SRV DNS lookup will be
|
|
performed and the URL will be constructed containing all host and port combinations
|
|
in priority and weighted order, utilizing `libpq's supoprt <https://www.postgresql.org/docs/12/libpq-connect.html>`_
|
|
for multiple hosts in a URL.
