ComparisonOperator enum

A comparison operator is an enumeration of several operations:

• EQ for equal.
• NE for not equal.
• IN checks for exact matches.
• LE for less than or equal to.
• LT for less than.
• GE for greater than or equal to.
• GT for greater than.
• BETWEEN for between.
• NOT_NULL for exists.
• NULL for not exists.
• CONTAINS for substring or value in a set.
• NOT_CONTAINS for absence of a substring or absence of a value in a set.
• BEGINS_WITH for a substring prefix.

Scan operations support all available comparison operators.

Query operations support a subset of the available comparison operators: EQ, LE, LT, GE, GT, BETWEEN, and BEGINS_WITH.
