Looker's User Attributes feature can be used to dynamically insert schema and/or table names on a per-user basis.
  The first step is to
  create a user attribute,
  such as custom_schema or custom_table, to which you
  will assign a value for each user. You can assign these values:
- Through the UI
- In bulk via the API
- In the SSO URL for embedded contexts.
  Once you have created the user attribute and assigned the appropriate value for
  your users, you can add a reference to that attribute in the
  sql_table_name of your view files, via
  Liquid variables.
  Following are two examples, one using a custom schema and one a custom table.
Example A
  Using a custom_schema:
view: events {
 sql_table_name: {{ _user_attributes['custom_schema'] }}.events ;;
 dimension: event_id {
   type: number
   primary_key: yes
   sql: ${TABLE}.id ;;
 }
}
Example B
  Using a custom_table:
view: events {
  sql_table_name: web_traffic.{{ _user_attributes['custom_event_table_name'] }} ;;
  dimension: event_id {
    type: number
    primary_key: yes
    sql: ${TABLE}.id ;;
 }
}
