v.20.10New Feature

Add LineAsString format for parsing sequences of lines as single String fields

Add format LineAsString that accepts a sequence of lines separated by newlines, every line is parsed as a whole as a single String field. #14703 (Nikita Mikhaylov), #13846 (hexiaoting).
Added a new data format LineAsString that treats each line in the input as a single string field.

Why it matters

This feature allows users to easily parse data where each line is intended to be a whole string without further splitting or parsing. It simplifies ingestion of raw line-separated text data into ClickHouse by automatically treating each line as a single string value.

How to use it

Use the LineAsString format when importing data via queries like INSERT INTO table FORMAT LineAsString. Each line in the input will be ingested as one string field.
