--------------------------------
Summary: Go Simple JSON Protocol re-allocates memory for every
escaped quote
Key: THRIFT-5767
URL: https://issues.apache.org/jira/browse/THRIFT-5767
Project: Thrift
Issue Type: Improvement
Components: Go - Library
Affects Versions: 0.19.0
Reporter: k walton
The current implementation of
[ParseQuotedStringBody()https://github.com/apache/thrift/blob/0e7236391f9ac7482f2e62a8c30155e015a80aa9/lib/go/thrift/simple_json_protocol.go#L953]
in the Go lib performs a memory allocation for every escaped quote in a string.
This is a particular problem for payloads with escaped JSON, which we ran into
causing performance issues in our application. Here is an example of the type
of payload I am referring to.
