Data type
In the traditional SQL world, a column data type can only be a simple data type, such as integer, boolean, and so on. Since data in Elasticsearch is represented as JSON, it supports data types that are complex and nested.
The different data types supported are as follows:
- Core data types:
- Text
- Keyword
- Date
- Numeric
- Boolean
- Binary
- Complex data types:
- Array
- Object (JSON object)
- Nested
- Geo data types:
- Geo-point
- Geo-shape
- Specialized data types:
- IP
Before we go through each data type, let's talk about the metafields each document contains.
