       A streamed result set consists of a stream of values, which might
       be split into many `PartialResultSet` messages to accommodate
       large rows and/or large values. Every N complete values defines a
       row, where N is equal to the number of entries in
       [metadata.row_type.fields][google.spanner.v1.StructType.fields].
      
       Most values are encoded based on type as described
       [here][google.spanner.v1.TypeCode].
      
       It is possible that the last value in values is "chunked",
       meaning that the rest of the value is sent in subsequent
       `PartialResultSet`(s). This is denoted by the [chunked_value][google.spanner.v1.PartialResultSet.chunked_value]
       field. Two or more chunked values can be merged to form a
       complete value as follows:
      
         * `bool/number/null`: cannot be chunked
         * `string`: concatenate the strings
         * `list`: concatenate the lists. If the last element in a list is a
           `string`, `list`, or `object`, merge it with the first element in
           the next list by applying these rules recursively.
         * `object`: concatenate the (field name, field value) pairs. If a
           field name is duplicated, then apply these rules recursively
           to merge the field values.
      
       Some examples of merging:
      
           # Strings are concatenated.
           "foo", "bar" => "foobar"
      
           # Lists of non-strings are concatenated.
           [2, 3], [4] => [2, 3, 4]
      
           # Lists are concatenated, but the last and first elements are merged
           # because they are strings.
           ["a", "b"], ["c", "d"] => ["a", "bc", "d"]
      
           # Lists are concatenated, but the last and first elements are merged
           # because they are lists. Recursively, the last and first elements
           # of the inner lists are merged because they are strings.
           ["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"]
      
           # Non-overlapping object fields are combined.
           {"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"}
      
           # Overlapping object fields are merged.
           {"a": "1"}, {"a": "2"} => {"a": "12"}
      
           # Examples of merging objects containing lists of strings.
           {"a": ["1"]}, {"a": ["2"]} => {"a": ["12"]}
      
       For a more complete example, suppose a streaming SQL query is
       yielding a result set whose rows contain a single string
       field. The following `PartialResultSet`s might be yielded:
      
           {
             "metadata": { ... }
             "values": ["Hello", "W"]
             "chunked_value": true
             "resume_token": "Af65..."
           }
           {
             "values": ["orl"]
             "chunked_value": true
             "resume_token": "Bqp2..."
           }
           {
             "values": ["d"]
             "resume_token": "Zx1B..."
           }
      
       This sequence of `PartialResultSet`s encodes two rows, one
       containing the field value `"Hello"`, and a second containing the
       field value `"World" = "W" + "orl" + "d"`.

       This sequence of `PartialResultSet`s encodes two rows, one
       containing the field value `"Hello"`, and a second containing the
       field value `"World" = "W" + "orl" + "d"`.
       
      repeated .google.protobuf.Value values = 2;
    • getChunkedValue

      boolean getChunkedValue()
       If true, then the final value in [values][google.spanner.v1.PartialResultSet.values] is chunked, and must
       be combined with more values from subsequent `PartialResultSet`s
       to obtain a complete field value.
       
      bool chunked_value = 3;
      Returns:
      The chunkedValue.
    • getResumeToken

      com.google.protobuf.ByteString getResumeToken()
       Streaming calls might be interrupted for a variety of reasons, such
       as TCP connection loss. If this occurs, the stream of results can
       be resumed by re-sending the original request and including
       `resume_token`. Note that executing any other transaction in the
       same session invalidates the token.
       
      bytes resume_token = 4;
      Returns:
      The resumeToken.
    • hasStats

      boolean hasStats()
       Query plan and execution statistics for the statement that produced this
       streaming result set. These can be requested by setting
       [ExecuteSqlRequest.query_mode][google.spanner.v1.ExecuteSqlRequest.query_mode] and are sent
       only once with the last response in the stream.
       This field will also be present in the last response for DML
       statements.
       
      .google.spanner.v1.ResultSetStats stats = 5;
      Returns:
      Whether the stats field is set.
    • getStats

      ResultSetStats getStats()
       Query plan and execution statistics for the statement that produced this
       streaming result set. These can be requested by setting
       [ExecuteSqlRequest.query_mode][google.spanner.v1.ExecuteSqlRequest.query_mode] and are sent
       only once with the last response in the stream.
       This field will also be present in the last response for DML
       statements.
       
      .google.spanner.v1.ResultSetStats stats = 5;
      Returns:
      The stats.
    • getStatsOrBuilder

      ResultSetStatsOrBuilder getStatsOrBuilder()
       Query plan and execution statistics for the statement that produced this
       streaming result set. These can be requested by setting
       [ExecuteSqlRequest.query_mode][google.spanner.v1.ExecuteSqlRequest.query_mode] and are sent
       only once with the last response in the stream.
       This field will also be present in the last response for DML
       statements.
       
      .google.spanner.v1.ResultSetStats stats = 5;
