A Python library to push ethereum blockchain data into an sql database.

ether_sql was built by Analyse Ether, with the goal of making Ethereum data easily available to everyone. This library can be used as a backbone for creating block explorers or performing data analysis.

It is written in Python 3.5+, uses for geting data using JSON-RPC calls and uses SqlAlchemy to connect to a postgressql database.

Buidl Status

This is currently in very alpha stage, and not recommended for production use until it has received sufficient testing. Currently supports Geth, Infura and Parity node, but transaction traces (eg. internal transactions) are currently available only with Parity node.

Command line options

ether_sql has several built in cli commands to facilitate scraping data.

This will start start pushing the data from an Infura node to the psql database.

Switching nodes

To switch nodes use the settings flag:

Using multiple workers to sync data

To start 4 parallel workers use.

$ ether_sql --settings=YourSettings celery start -c4

The above command will start 4 workers using the settings YourSettings Then start the sync, which will automatically use the setting used to start workers. $ ether_sql scrape_block_range

Here is a demo of the process:
