BigQuery (Google BigQuery)

One of the most robust Cloud Data Warehouse solutions, and arguably the first, available on the market today it is a no brainer that we have Google BigQuery as a target system for DLH.io.

In order to get setup on BigQuery we use a sophisticated but elegant solution which aligns with open standards and uses the best pratices prescribed by Google, as well as a few that we have learned over hundreds of customer interactions.

Use this section of the documentation to explore:

BigQuery Case Sensitivity

Currently DLH.io abides by the case-sensitivity of BigQuery. This means that the dataset/schema and the tables are case-senstive when created and populated by DLH.io. As a future feature we will allow a force case-insensitive feature. In which case once will need to understand if their source connection has any case sensitivity which could result in an issue as the data is loaded into the target. There is potential for case-insensitivity to bcome the default standard of DLH.io

Per the BigQuery documentation on their lexical structure and syntax there are different uses of case sensitivity in the BigQuery platform.

If using the is_case_insensitive option, note that it cannot be used for ALTER SCHEMA only for CREATE SCHEMA (ref: https://cloud.google.com/bigquery/docs/reference/standard-sql/data-definition-language#schema_option_list). This is set when creating the SCHEMA as follows:
