Tasks

Stuff to implement, in no particular order:

• Essentials

  • nice looking results
  • query execution
  • toggle numbers formatting on/off
  • string truncation (aka max column width)
  • expanded output
  • switch GCP projects during session
  • nicer looking errors/warnings
  • multiline queries
  • multiline results in cells
  • some kind of authentication flow if there's no service account provided
  • persist query history in local database
  • query result pagination or whatever is required to keep # results sane

• Command line arguments:

  • service-account
  • project
  • execute SQL from command line

• code completion:

  • BQ-specific SQL syntax
  • projects/datasets/tables/columns available in the query context
  • BQ commands

• BQ commands

  • list projects
  • list datasets
  • list tables
  • list datasets in a specific project
  • list columns
  • show info about dataset/table/view/model
  • filter list
  • copy tables
  • extract (table to bucket)
  • insert rows to table (from local file)
  • create dataset
  • create table

• Extras

  • colour-coding nulls
  • colour-coding floats/integers/strings/dates (do I even need this?)
  • recall cached query results instead of running them again
  • view results in a horizontally scrollable table (like pgcli)
  • project/dataset tree
  • use tabs for query results?
  • async queries
  • clear screen
  • ? help command
