--------------------------------------
Summary: Support raw string literal
Key: SPARK-36371
URL: https://issues.apache.org/jira/browse/SPARK-36371
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 3.3.0
Reporter: Kousuke Saruta
Assignee: Kousuke Saruta
In the current master, sometimes it's too confusable to represent JSON and
regex in a string literal if they contain backslash.
For example, in JSON, \ needs to be escaped like as follows.
{code}
{"a": "\\"}
{code}
But, if the JSON above is represented in a string literal, further two \ are
needed because string literal also requires \ to be escaped.
{code}
SELECT from_json('{"a": "\\\\"}', 'a string')
{"a":"\"}
{code}
To make such case simpler, it's great if Spark supports raw string literal.
