+Datasources in Apache Druid are things that you can query. The most common
kind of datasource is a table datasource,
+and in many contexts the word "datasource" implicitly refers to table
datasources. This is especially true
+[during data ingestion](../ingestion/index.html), where ingestion is always
creating or writing into a table
+datasource. But at query time, there are many other types of datasources
available.
-A data source is the Apache Druid equivalent of a database table. However, a
query can also masquerade as a data source, providing subquery-like
functionality. Query data sources are currently supported only by
[GroupBy](../querying/groupbyquery.md) queries.
+In the [Druid SQL](sql.html) language, datasources are provided in the [`FROM`
clause](sql.html#from).
-### Table datasource
-The table data source is the most common type. It's represented by a string,
or by the full structure:
+The word "datasource" is generally spelled `dataSource` (with a capital S)
when it appears in API requests and
+responses.
+## Datasource type

Review comment:
I don't think these intervals match the intervals used by the sql query in
the tab above
