public final class RoutingHint extends com.google.protobuf.GeneratedMessageV3 implements RoutingHintOrBuilder
 `RoutingHint` can be optionally added to location-aware Spanner
 requests. It gives the server hints that can be used to route the request to
 an appropriate server, potentially significantly decreasing latency and
 improving throughput. To achieve improved performance, most fields must be
 filled in with accurate values.

 The presence of a valid `RoutingHint` tells the server that the client
 is location-aware.

 `RoutingHint` does not change the semantics of the request; it is
 purely a performance hint; the request will perform the same actions on the
 database's data as if `RoutingHint` were not present. However, if
 the `RoutingHint` is incomplete or incorrect, the response may include
 a `CacheUpdate` the client can use to correct its location cache.

    • getOperationUid

      public long getOperationUid()
       A session-scoped unique ID for the operation, computed client-side.
 Requests with the same `operation_uid` should have a shared 'shape',
 meaning that some fields are expected to be the same, such as the SQL
 query, the target table/columns (for reads) etc. Requests with the same
 `operation_uid` are meant to differ only in fields like keys/key
 ranges/query parameters, transaction IDs, etc.

 `operation_uid` must be non-zero for `RoutingHint` to be valid.
      uint64 operation_uid = 1;
      Specified by:
      getOperationUid in interface RoutingHintOrBuilder
      Returns:
      The operationUid.

    • getDatabaseId

      public long getDatabaseId()
       The database ID of the database being accessed, see
 `CacheUpdate.database_id`. Should match the cache entries that were used
 to generate the rest of the fields in this `RoutingHint`.
      uint64 database_id = 2;
      Specified by:
      getDatabaseId in interface RoutingHintOrBuilder
      Returns:
      The databaseId.

    • getSchemaGeneration

      public com.google.protobuf.ByteString getSchemaGeneration()
       The schema generation of the recipe that was used to generate `key` and
 `limit_key`. See also `RecipeList.schema_generation`.
      bytes schema_generation = 3;
      Specified by:
      getSchemaGeneration in interface RoutingHintOrBuilder
      Returns:
      The schemaGeneration.

    • getKey

      public com.google.protobuf.ByteString getKey()
       The key / key range that this request accesses. For operations that
 access a single key, `key` should be set and `limit_key` should be empty.
 For operations that access a key range, `key` and `limit_key` should both
 be set, to the inclusive start and exclusive end of the range respectively.

 The keys are encoded in "sortable string format" (ssformat), using a
 `KeyRecipe` that is appropriate for the request. See `KeyRecipe` for more
 details.
      bytes key = 4;
      Specified by:
      getKey in interface RoutingHintOrBuilder
      Returns:
      The key.

    • getLimitKey

      public com.google.protobuf.ByteString getLimitKey()
       If this request targets a key range, this is the exclusive end of the
 range. See `key` for more details.
      bytes limit_key = 5;
      Specified by:
      getLimitKey in interface RoutingHintOrBuilder
      Returns:
      The limitKey.

    • getGroupUid

      public long getGroupUid()
       The group UID of the group that the client believes serves the range
 defined by `key` and `limit_key`. See `Range.group_uid` for more details.
      uint64 group_uid = 6;
      Specified by:
      getGroupUid in interface RoutingHintOrBuilder
      Returns:
      The groupUid.

    • getSplitId

      public long getSplitId()
       The split ID of the split that the client believes contains the range
 defined by `key` and `limit_key`. See `Range.split_id` for more details.
      uint64 split_id = 7;
      Specified by:
      getSplitId in interface RoutingHintOrBuilder
      Returns:
      The splitId.

    • getTabletUid

      public long getTabletUid()
       The tablet UID of the tablet from group `group_uid` that the client
 believes is best to serve this request. See `Group.local_tablet_uids` and
 `Group.leader_tablet_uid`.
      uint64 tablet_uid = 8;
      Specified by:
      getTabletUid in interface RoutingHintOrBuilder
      Returns:
      The tabletUid.

       If the client had multiple options for tablet selection, and some of its
