What does the Chicago IL 311 data include?

One table, service requests, with one row per service request.

Do I need an account with Chicago IL 311?

No. The data is public, so there is nothing to sign up for and nothing to paste in.

How fresh is the data?

As fresh as your schedule: daily by default, or weekly or monthly. Schedules as often as every 15 minutes are on the Enterprise plan. Each run adds requests created since the last run. A request changed later, for example when it is closed, keeps the values it had when first loaded.

Will running it again create duplicate rows?

No. Each row is stored once, by its key: when a run reads a row that is already there, it replaces that copy instead of adding a second one.

Do I need to write code?

No. Ingest builds, runs and maintains the connector. Someone with access to your warehouse connects it once, following a short guide.
