Description

Adding the following 2 APIs cassandra sidecar which are required for adding Change Data Capture feature into C*. These are the API contracts only, and do not implement the full CDC functionality. That will be added in a follow up.

• Listing CDC commitlogs/segments
• API : "GET api/v1/cdc/segments"
• Lists all the CDC commit logs on a given cassandra instance.
• Response :

           {
                "host":"127.0.0.1",
                "port":0,
                "segmentInfos":[
                {
                     "name":"CommitLog-1-1.log",
                    "size":1,
                    "idx":1,
                    "completed":true,
                    "lastModifiedTimestamp":1733182677704
                }
              ]
          }
          

• Streaming Commitlogs/segments
• API: "GET /cdc/segments/CommitLog-1-1.log"
• Streams CDC commit log file
• Response: Streams the file content.
