# [DRILL-8020](https://issues.apache.org/jira/browse/DRILL-8020): Add JSON Configuration Options to HTTP Rest Plugin ## Description This PR allows users to configure how Drill reads incoming JSON from individual API connections. It has the effect of overriding the system-wide settings for JSON, within the context of a specific API connection. ## Documentation Drill has a collection of JSON configuration options to allow you to configure how Drill interprets JSON files. These are set at the global level, however the HTTP plugin allows you to configure these options individually per connection and override the Drill defaults. The options are: * `allowNanInf`: Configures the connection to interpret `NaN` and `Inf` values * `allTextMode`: By default, Drill attempts to infer data types from JSON data. If the data is malformed, Drill may throw schema change exceptions. If your data is inconsistent, you can enable `allTextMode` which when true, Drill will read all JSON values as strings, rather than try to infer the data type. * `readNumbersAsDouble`: By default Drill will attempt to interpret integers, floating point number types and strings. One challenge is when data is consistent, Drill may throw schema change exceptions. In addition to `allTextMode`, you can make Drill less sensitive by setting the `readNumbersAsDouble` to `true` which causes Drill to read all numeric fields in JSON data as `double` data type rather than trying to distinguish between ints and doubles. * `enableEscapeAnyChar`: Allows a user to escape any character with a \ All of these can be set by adding the `jsonOptions` to your connection configuration as shown below: ```json "jsonOptions": { "allTextMode": true, "readNumbersAsDouble": true } ``` ## Testing Added unit test -- This is an automated message from the Apache Git Service.
