selective permanode feature

[louaykamel]

Currently Chronicle is designed to store the full history of Tangle, but I believe a selective feature is an important one that we should implement after the first release.

Data model:

• Transaction Table (the single source of truth)
  • Each row represents a unique transaction.
  • Point query by transaction hash.
• Edge Table (index table)
  • Each row represents a relation to a transaction hash
  • Point queries by address/trunk/branch/bundle
• Data Table (index table)
  • Hold unbounded relations(tags/zero-value-address)
  • Point queries by address/tag followed by year and month
  • Timeserise lookup

Enhancements:

• Let the node owner defines what to insert/index into each table
• Triggers when a certain condition is met
  • Example: trigger a microservice to do something

Can only be implemented after solidifier implementation.
