Data Extraction Efficiency

[joaquinps]

When using Ethereum ETL for data extraction, how can the extraction process be optimized for efficiency, especially when working with large blockchain data?

Optimization Strategies

1. Use export_all for Full Extraction

Extract all standard datasets (blocks, transactions, logs, token transfers, traces, contracts, tokens) at once.

ethereumetl export_all \
  --provider-uri https://mainnet.infura.io/v3/YOUR_KEY \
  --start-block 0 \
  --end-block latest \
  --output-dir output

### 2. Run a Local Archive Node

geth \
  --syncmode full \
  --gcmode=archive \
  --http \
  --http.api=eth,debug,trace

For full-scale or trace-heavy extractions.

### 3. Use Multi-threading

--max-workers 8

Depend on your Cpu

### 4. Batch Extraction by Block Ranges

for i in {0..10000000..100000}; do
  ethereumetl export_blocks_and_transactions \
    --start-block $i \
    --end-block $(($i + 99999)) \
    --provider-uri http://localhost:8545 \
    --output-dir output \
    --max-workers 4
done

Avoid extracting millions of blocks at once.
