Key: PHOENIX-7585
URL: https://issues.apache.org/jira/browse/PHOENIX-7585
Project: Phoenix
Issue Type: Improvement
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 (similar to
field_exists(), field_not_exists() etc) within BSON_CONDITION_EXPRESSION()
function such that it can identify whether the value of the given document
field of type BsonString or BsonBinary has prefix value as the constant
provided in the second argument.
begins_with(path, substr) => here, path represents path in the given BSON
document. substr represents value which needs to be compared as the prefix
value of path field from the document.
