Background

Tasks

• Create indexer for governance items and persist them in ddb
• Cover indexer with tests
• New governance controller:
  1. getProposals - provide summary of proposals in a paginated state including info such as
  - proposal id
  - proposal state
  - time proposed
  2. getProposalData - provide break down of proposal information
  - proposer
  - num approved / rejected
  - proposal state
  - time proposed
  - proposal state history
• Provide tests coverage for controller
• Create indexer(schedule) task, that will decode CallData from CallScheduled event
  • fetch abi from scan resource
  • find method depending on its hash
  • decode data and save to ddb, as a new field

In case, if indexer will fail on init with timeouts, coz of massive scan ranges (over 10kk)

• Metadata table (with blocks number and action name) for indexing events for the long range and first launches
