gethtomysql
Basic nodejs to import ethereum blockchain from a geth node to mysql
Edit sql queries in source.js to adapt them to your mysql db
You need the genesis block with id 0 in your blocks table
If you want to restart the import, just delete all blocks from the db and leave the genesis block
node source.js
When synced, it listens for new blocks and add them to the database.
It supports blocks data, txs, address balances and tx history.
PostgreSQL
psql.py is for postgre, with web3 ipc provider. It is more than 50x faster in the import and it can stay behind a private network with 1s block time.
This can be used for a high performance explorer, it is currently tested on an explorer made with Django, CitusDB and a blockchain with 1s block time. It is handling more than 500k blocks with an average of 25 transactions per block
Notes
It automatically skips empty block, but you can easily disabling this in the syncblock function
