----------------------------------
Summary: Rope-wise dumping of Spark plans
Key: SPARK-26504
URL: https://issues.apache.org/jira/browse/SPARK-26504
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Maxim Gekk
Currently, Spark plans are converted to string via StringBuilderWriter when
memory for strings are allocated sequentially as soon as elements of plans are
added to the StringBuilder.
Proposed improvement is StringRope which has 2 methods:
1. append(s: String): Unit - adds the string to internal list and increases
total size
2. toString: String - converts the list of strings to strings
