Schemas and utils for IPLD ETH Postgres database

Database UML

Run

  • Remove any existing containers / volumes:

    docker-compose down -v --remove-orphans
    
  • Spin up ipld-eth-db using an existing image:

    • Update image source used for running the migrations in docker-compose.yml (if required).

    • Run:

      docker-compose -f docker-compose.yml up
      
  • Spin up ipld-eth-db using a locally built image:

    • Update Dockerfile (if required).

    • Update build context used for running the migrations in docker-compose.test.yml (if required).

    • Run:

      docker-compose -f docker-compose.test.yml up --build
      

Example queries

Note that searching by block_number in addition to block_hash is optional in the below queries where both are provided, but since the tables are partitioned by block_number doing so will improve query performance by informing the query planner which partition it needs to search.

Headers

Retrieve header RLP (IPLD block) and CID for a given block hash

SELECT header_cids.cid,
       blocks.data
FROM ipld.blocks,
     eth.header_cids
WHERE header_cids.block_hash = {block_hash}
    AND header_cids.block_number = {block_number}
	AND header_cids.canonical
	AND blocks.key = header_cids.cid
	AND blocks.block_number = header_cids.block_number
LIMIT 1

Uncles

Retrieve the uncle list RLP (IPLD block) and CID for a given block hash

SELECT uncle_cids.cid,
       blocks.data
FROM eth.uncle_cids
INNER JOIN eth.header_cids ON (
    uncle_cids.header_id = header_cids.block_hash
    AND uncle_cids.block_number = header_cids.block_number)
INNER JOIN ipld.blocks ON (
    uncle_cids.cid = blocks.key
    AND uncle_cids.block_number = blocks.block_number)

ORDER BY uncle_cids.parent_hash
LIMIT 1

Transactions

INNER JOIN ipld.blocks ON (
    receipt_cids.cid = blocks.key
    AND receipt_cids.block_number = blocks.block_number)
WHERE transaction_cids.tx_hash = {transaction_hash}
