Key: PHOENIX-7662
URL: https://issues.apache.org/jira/browse/PHOENIX-7662
Project: Phoenix
Issue Type: New Feature
Reporter: Viraj Jasani
PHOENIX-7463 provides us with the ability to generate and evaluate AST
(Abstract Syntax Tree) for the BSON condition expression evaluation for it's
SQL type expressions.
The purpose of this Jira is to provide a new internal function for
BSON_CONDITION_EXPRESSION() to help evaluate whether value of the given field
key contains a particular value.
contains(fieldKey, val) => here, fieldKey represents field key's path in the
given BSON document. val represents value which needs to be compared.
The function evaluation returns true if the value of the field contains the
specified value. The field can be:
* A string that contains a particular substring
* A set that contains a particular element within the set
* A list that contains a particular element within the list
