"""fetch
Fetch all supported datasets for a stock ``ticker`` or
a list of ``tickers`` and returns a dictionary. Once
run, the datasets will all be cached in Redis and archived
in Minio (S3) by default.
Python example:
.. code-block:: python
from analysis_engine.fetch import fetch
d = fetch(ticker='NFLX')
print(d)
for k in d['NFLX']:
print('dataset key: {}'.format(k))
By default, it synchronously automates:
- fetching all datasets
- caching all datasets in Redis
- archiving all datasets in Minio (S3)
- returns all datasets in a single dictionary
This was created for reducing the amount of typying in
Jupyter notebooks. It can be set up for use with a
distributed engine as well with the optional arguments
depending on your connectitivty requirements.
.. note:: Please ensure Redis and Minio are running
before trying to extract tickers

"""extract
Extract all cached datasets for a stock ``ticker`` or
a list of ``tickers`` and returns a dictionary. Please
make sure the datasets are already cached in Redis
before running this method. If not please refer to
the ``analysis_engine.fetch.fetch`` function
to prepare the datasets on your environment.
Python example:
.. code-block:: python
from analysis_engine.extract import extract
d = extract(ticker='NFLX')
print(d)
for k in d['NFLX']:
print('dataset key: {}'.format(k))
This was created for reducing the amount of typying in
Jupyter notebooks. It can be set up for use with a
distributed engine as well with the optional arguments
depending on your connectitivty requirements.
.. note:: Please ensure Redis and Minio are running
before trying to extract tickers
**Stock tickers to extract**
:param ticker: single stock ticker/symbol/ETF to extract
:param tickers: optional - list of tickers to extract
:param use_key: optional - extract historical key from Redis
usually formatted ``<TICKER>_<date formatted YYYY-MM-DD>``
**(Optional) Data sources, datafeeds and datasets to gather**
:param iex_datasets: list of strings for gathering specific `IEX
datasets <https://iextrading.com/developer/docs/#stocks>`__
which are set as consts: ``analysis_engine.iex.consts.FETCH_*``.
**(Optional) Redis connectivity arguments**
:param redis_enabled: bool - toggle for auto-caching all
datasets in Redis
(default is ``True``)
:param redis_address: Redis connection string format: ``host:port``
(default is ``localhost:6379``)
:param redis_db: Redis db to use
(default is ``0``)
:param redis_password: optional - Redis password
(default is ``None``)
:param redis_expire: optional - Redis expire value
(default is ``None``)
**(Optional) Minio (S3) connectivity arguments**
:param s3_enabled: bool - toggle for auto-archiving on Minio (S3)
(default is ``True``)
:param s3_address: Minio S3 connection string format: ``host:port``
(default is ``localhost:9000``)
:param s3_bucket: S3 Bucket for storing the artifacts
(default is ``dev``) which should be viewable on a browser:
http://localhost:9000/minio/dev/
:param s3_access_key: S3 Access key
(default is ``trexaccesskey``)
:param s3_secret_key: S3 Secret key
(default is ``trex123321``)
:param s3_region_name: S3 region name
(default is ``us-east-1``)
:param s3_secure: Transmit using tls encryption
(default is ``False``)
**(Optional) Celery worker broker connectivity arguments**
:param celery_disabled: bool - toggle synchronous mode or publish
to an engine connected to the `Celery broker and backend
<https://github.com/celery/celery#transports-and-backends>`__
(default is ``True`` - synchronous mode without an engine
or need for a broker or backend for Celery)
:param broker_url: Celery broker url
(default is ``redis://0.0.0.0:6379/13``)
:param result_backend: Celery backend url
(default is ``redis://0.0.0.0:6379/14``)
:param label: tracking log label
**(Optional) Debugging**
:param verbose: bool - show extract warnings
and other debug logging (default is False)
