Milestone 1

[sh-rn]

Goal: Basic functionality same as XQuery 1.0, improved performance & code, added state management

To do:

• overhaul project/code structure - modular approach
• add redis cache
• shared between all workers
• add multiprocessing
• add proper state management
• handle re-orgs (simple strategy: only index up to "latest - N safety blocks") - handle errors/crashes
• handle start/stop ("resume" feature)
• rework event log fetching, filtering (focus on improving speed) - make use of 'eth_getLogs'
• keep database model and event processing from XQuery 1.0
• single table database for simplicity

QA: - requires more detail from the dev

• redis cache implemented
• shared between all workers ?
• multiprocessing
• state management ?
