      • getChunksCount

        public int getChunksCount()
         A collection of a row's contents as part of the read request.
        repeated .google.bigtable.v2.ReadRowsResponse.CellChunk chunks = 1;
        Specified by:
        getChunksCount in interface ReadRowsResponseOrBuilder

      • getLastScannedRowKey

        public com.google.protobuf.ByteString getLastScannedRowKey()
         Optionally the server might return the row key of the last row it
 has scanned.  The client can use this to construct a more
 efficient retry request if needed: any row keys or portions of
 ranges less than this row key can be dropped from the request.
 This is primarily useful for cases where the server has read a
 lot of data that was filtered out since the last committed row
 key, allowing the client to skip that work on a retry.
        bytes last_scanned_row_key = 2;
        Specified by:
        getLastScannedRowKey in interface ReadRowsResponseOrBuilder
        Returns:
        The lastScannedRowKey.

      • hasRequestStats

        public boolean hasRequestStats()
        
 If requested, provide enhanced query performance statistics. The semantics
 dictate:
   * request_stats is empty on every (streamed) response, except
   * request_stats has non-empty information after all chunks have been
     streamed, where the ReadRowsResponse message only contains
     request_stats.
       * For example, if a read request would have returned an empty
         response instead a single ReadRowsResponse is streamed with empty
         chunks and request_stats filled.

 Visually, response messages will stream as follows:
    ... -> {chunks: [...]} -> {chunks: [], request_stats: {...}}
   \______________________/  \________________________________/
       Primary response         Trailer of RequestStats info

 Or if the read did not return any values:
   {chunks: [], request_stats: {...}}
   \________________________________/
      Trailer of RequestStats info
        .google.bigtable.v2.RequestStats request_stats = 3;
        Specified by:
        hasRequestStats in interface ReadRowsResponseOrBuilder
        Returns:
        Whether the requestStats field is set.

      • getRequestStats

        public RequestStats getRequestStats()
        
 If requested, provide enhanced query performance statistics. The semantics

   * request_stats has non-empty information after all chunks have been
     streamed, where the ReadRowsResponse message only contains

        .google.bigtable.v2.RequestStats request_stats = 3;
        Specified by:
        getRequestStats in interface ReadRowsResponseOrBuilder
        Returns:
        The requestStats.
