Logstash custom pattern for grok filter

[vasudevan]

We have a log file in which we are reading specific lines and storing it against a field for that we are using below mentioned config but it's look lengthy, repetitive and not professional but serves the purpose. I hope there is a better way to do that instead adding each grok for each line, Please suggest us
Note: I didn't post the full logstash config but posted the repeated part

You can use an array of patterns to match. They will be a lot more efficient if you anchor them to start of line using ^

    grok {
        add_tag => [ "start" ]
        match => {
            "message" => [
                "^\[%{TIMESTAMP_ISO8601:build_StartTime}",
                '^"%{WORD}\.definitionName": "(?<build_DefinitionName>.+)"',
                '^"%{WORD}\.requestedFor": "(?<build_RequesterName>.+)"',
                '^"%{WORD}\.buildNumber": "(?<build_BuildNumber>.+)"',
                '^"%{WORD}\.teamProject": "(?<build_TeamProject>.+)"',
                '^"%{WORD}\.sourceVersion": "(?<build_SourceVersion>.+)"',
                '^"%{WORD}\.sourceBranchName": "(?<build_SourceBranchName>.+)"',
                '^"%{WORD}\.buildId": "(?<build_BuildId>.+)"',
                '^"%{WORD}\.reason": "(?<build_Reason>.+)"',
                '^"%{WORD}\.teamFoundationCollectionUri": "(?<build_TeamFoundationCollectionUri>.+)"',
                '^"%{WORD}\.repository.uri": "(?<build_RepositoryUri>.+)"',
                '^"%{WORD}\.sourceVersionAuthor": "(?<build_SourceVersionAuthor>.+)"',
                '^"%{WORD}\.sourceVersionMessage": "(?<build_SourceVersionMessage>.+)"'
            ]
        }
        tag_on_failure => []
    }
