Timeseries database project: For storing potentially changing timeseries data. For example hydrological data, like streamflow data, where the timeseries may be revised as quality control processes improve the recorded dataset over time.
PhilDB should be capable of storing data at any frequency supported by Pandas. At this time only daily data has been extensively tested with some limited sub-daily usage.
Further information about the design of PhilDB can be found in the paper:
PhilDB: the time series database with built-in change logging <https://peerj.com/articles/cs-52/>
_.
That paper explores existing time series database solutions, discusses the
motivation for PhilDB, describes the architecture and philosophy of the PhilDB
software, and includes an evaluation between InfluxDB, PhilDB, and SciDB.
Dependencies
Requires Python 3.7 or greater (mostly tested on Mac OSX and Linux). Test suite runs on Linux using Travis CI with Python 3.6, 3.7, and 3.8. Test suite runs on Windows using Appveyor with Python 3.7.
All the python dependencies are recorded in the python_requirements file.
Installation
PhilDB is pip installable.
The latest stable version can be installed from pypi with::
pip install phildb
The latest stable version can also be installed from conda with::
conda install -c amacd31 phildb
The latest development version can be installed from github with::
pip install git+https://github.com/amacd31/[email protected]
The latest development version can be installed from conda with::
conda install -c amacd31/label/dev phildb
Development environment ^^^^^^^^^^^^^^^^^^^^^^^
A number of processes for a development environment with tests and documentation generation have been automated in a Makefile.
The virtualenv package can be used to create an isolated install of required Python packages.
Create a virtual environment with dependencies installed:
::
make venv
Test everything is working:
::
make test
Build the documentation:
::
make docs
View the generated documentation at doc/build/html/index.html
For additional details see the INSTALL file.
Usage
Create a new PhilDB
::
phil-create new_tsdb
Open the newly created PhilDB
::
phildb new_tsdb
If using the development environment built with make, Load it along with adding PhilDB tools to your path:
::
. load_env
Examples
See the examples directory for code on setting up test phil databases with different data sets. Each example comes with a README file outlining the steps to acquire some data and load it. The loading scripts in each example can be used as a basis for preparing a timeseries database and loading it with data.
The examples/hrs/ example also contains an example script (autocorr.py) for processing the HRS data using phildb. The script calculates auto-correlation for all the streamflow timeseries in the HRS dataset.
Presently there are three sets of example code, acorn-sat, bom_observations, and hrs.
ACORN-SAT
ACORN-SAT Example.ipynb <https://github.com/amacd31/phildb/blob/master/examples/acorn-sat/ACORN-SAT%20Example.ipynb>
_ located in examples/acorn-sat demonstrates loading minimum
and maximum daily temperature records for 112 stations around Australia.
The dataset used in this example is the Australian Climate Observations
Reference Network – Surface Air Temperature (ACORN-SAT) as found on the
Australian Bureau of Meteorology website
ACORN-SAT website <http://www.bom.gov.au/climate/change/acorn-sat/>
_.
BOM Observations
Bureau of Meterology observations example.ipynb <https://github.com/amacd31/phildb/blob/master/examples/bom_observations/Bureau%20of%20Meterology%20observations%20example.ipynb>
_
located in examples/bom_observations demonstrates loading
half hourly air temperature data from a 72 hour observations JSON file.
The data used in this example is a 72 hour observations JSON file from
the Australian Bureau of Meteorology website (e.g. JSON file as linked
on this page: Sydney Airport observations <http://www.bom.gov.au/products/IDN60901/IDN60901.94767.shtml#other_formats>
_
HRS
HRS Example.ipynb <https://github.com/amacd31/phildb/blob/master/examples/hrs/HRS%20Example.ipynb>
_
located in examples/hrs demonstrates loading daily
streamflow data for 221 streamflow stations around Australia.
The dataset used in this example is the Hydrologic Reference Stations
(HRS) dataset as found on the Australian Bureau of Meteorology website
HRS website <http://www.bom.gov.au/water/hrs/>
_.
This example also includes a script to calculate the auto-correlation for all the streamflow timeseries in the HRS dataset.
