aswan

collect and organize data into a T1 data depot named after the Aswan Dam

Collect and compress data from the internet for later parsing

• quick, parallel, customizable to collect
• compressed to store
• quick to sync with a remote store
  • sync to continue collecting
  • sync to parse
• immutable collection

To Setup a Remote

set the environment variables ASWAN_AUTH_HEX and ASWAN_AUTH_PASS according to the zimmauth package, and ASWAN_REMOTE with the name of the default remote.

Concepts

• objects
  • saved by collection events
• events
  • collection
  • registration (v2: registration for parsing)
  • (v2) parsing
• runs
  • manual run vs automated run
    • makes manual adding of urls easy but revertible
  • has unique id
  • generates events
  • linked to a specific version of the code
    • ideally commit hash + pip freeze
• statuses
  • determined by base status + runs integrated
  • contains
    • what urls need to be collected
    • (v2) what collected objects need to be parsed
  • sqlite file, constantly trimmed

Structure

• objects

  • 00, 01, ...

• runs

  • run-hash
    • context.yaml
      • commit-hash, pip-freeze, ...
    • events.zip

• statuses

  • status-hash
    • context.yaml
      • parent-status, integrated
    • db.sqlite.zip

• current-run

  • context.yaml
  • events
    • these to be compressed into ../runs
  • status.sqlite

• there is a 'TEST' status

  • cannot be integrated whatever is based on it
  • a test run can be made on it...

when starting a run:

• check if current-run is empty
  • if not, fail with
• find latest status
  • if it has not integrated all past runs, create a new status that has
• start collection (+ registration)
• either stops or breaks, all events and objects are saved to disk
• if properly stops, move and compress stuff
  • based on one that was the starter, and current run id

Pre v1.0 laundry list

• parallelize push / pull

• parsing/connection/broken session error docs

• transferring / ignoring cookies

• template projects

  • oddsportal
    • updating thingy, based on latest match in season
  • footy
  • rotten
