Work with semi-structured data
ARRAY, as an extended type of database, is supported in various database systems such as PostgreSQL, ClickHouse, and Snowflake. ARRAY is widely used in scenarios such as A/B tests, user tag analysis, and user profiling. StarRocks supports multidimensional array nesting, array slicing, comparison, and filtering.
StarRocks starts to support the JSON data type since v2.2.0. This topic describes the basic concepts of JSON. It also describes how to create a JSON column, load JSON data, query JSON data, and use JSON functions and operators to construct and process JSON data.
