cerebralcortex-kernel 3.0.0.post17

Backend data analytics platform for MD2K software

# CerebralCortex Kernel Cerebral Cortex is the big data cloud companion of mCerebrum designed to support population-scale data analysis, visualization, model development, and intervention design for mobile sensor data.

You can find more information about MD2K software on our [software website](https://md2k.org/software) or the MD2K organization on our [MD2K website](https://md2k.org/).

CerebralCortex Kernel is part of our [CerebralCortex cloud platform](https://github.com/MD2Korg/CerebralCortex). CerebralCortex Kernel is mainly responsible to store/retrieve mobile sensor data along with it’s metadata.

Note:

We have renamed following repositories.

• CerebralCortex-Platform -> CerebralCortex

• CerebralCortex - > CerebralCortex-Kernel

## Examples - [How to use CerebralCortex-Kernel API](https://github.com/MD2Korg/CerebralCortex-kernel-Examples)

## Documentation

• [Source code documentation](https://cerebralcortex-kernel.readthedocs.io/en/latest/)

## Installation CerebralCortex-Kernel is a part of CerebralCortex cloud platform. To test the complete cloud platform, please visit [CerebralCortex](https://github.com/MD2Korg/CerebralCortex).

CerebralCortex-Kernel requires minimum [Python3.6](https://www.python.org/downloads/release/python-360/). To install CerebralCortex-Kernel as an API:

`pip3 install cerebralcortex-kernel`

• Note: please use appropriate pip (e.g., pip, pip3, pip3.6 etc.) installed on your machine

### Dependencies

• Python3.6

  • Note: Python3.7 is not compatible with some of the requirements

  • Make sure pip version matches Python version

## FAQ 1 - Do I need whole CerebralCortex cloud platform to use CerebralCortex-Kernal?

No! If you want to use CerebralCortex-Kernel independently then you would need: * Backend storage (FileSystem/HDFS and MySQL) with some data. Here is [some sample data](TODO) to play with. * Setup the [configurations](https://github.com/MD2Korg/CerebralCortex-Kernel/tree/master/conf) * Use the [examples](TODO) to start exploring data

2 - How can I change NoSQL storage backend?

CerebralCortex-Kernel follows component based structure. This makes it easier to add/remove features. * Add a new class in [Data manager-Raw](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/cerebralcortex/core/data_manager/raw/). * New class must have read/write methods. Here is a sample [skeleton class](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/cerebralcortex/core/data_manager/raw/storage_blueprint.py) with mandatory methods required in the new class. * Create an object of new class in [Data-Raw](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/cerebralcortex/core/data_manager/raw/data.py) with appropriate parameters. * Add appropriate configurations in [cerebralcortex.yml](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/conf/cerebralcortex.yml) in (NoSQL Storage)[https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/conf/cerebralcortex.yml#L8] section.

3 - How can I replace MySQL with another SQL storage system?

• Add a new class in [Data manager-SQL](https://github.com/MD2Korg/CerebralCortex-Kernel/tree/master/cerebralcortex/core/data_manager/sql).

• New class must implement all of the methods available in (stream_handler.py)[https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/cerebralcortex/core/data_manager/sql/stream_handler.py] class.

• Create an object of new class in [Data-SQL](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/cerebralcortex/core/data_manager/sql/data.py) with appropriate parameters.

• Add appropriate configurations in [cerebralcortex.yml](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/conf/cerebralcortex.yml) in (Relational Storage)[https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/conf/cerebralcortex.yml#L31] section.

4 - Where are all the backend storage related classes/methods?

In [Data manager-Raw](https://github.com/MD2Korg/CerebralCortex-Kernel/blob/master/cerebralcortex/core/data_manager/). You can add/change any backend storage.
