getIndex
String getIndex()
If non-empty, the name of an index on [table][google.spanner.v1.ReadRequest.table]. This index is used instead of the table primary key when interpreting [key_set][google.spanner.v1.ReadRequest.key_set] and sorting result rows. See [key_set][google.spanner.v1.ReadRequest.key_set] for further information.
string index = 4;
- Returns:
- The index.
-
getIndexBytes
com.google.protobuf.ByteString getIndexBytes()
If non-empty, the name of an index on [table][google.spanner.v1.ReadRequest.table]. This index is used instead of the table primary key when interpreting [key_set][google.spanner.v1.ReadRequest.key_set] and sorting result rows. See [key_set][google.spanner.v1.ReadRequest.key_set] for further information.
string index = 4;
- Returns:
- The bytes for index.
-
getColumnsList
List<String> getColumnsList()
Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching this request.
repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];
- Returns:
- A list containing the columns.
-
getColumnsCount
int getColumnsCount()
Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching this request.
repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];
- Returns:
- The count of columns.
-
getColumns
String getColumns(int index)
Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching this request.
repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];
- Parameters:
index
- The index of the element to return.- Returns:
- The columns at the given index.
-
getColumnsBytes
com.google.protobuf.ByteString getColumnsBytes(int index)
Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching this request.
repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];
- Parameters:
index
- The index of the value to return.- Returns:
- The bytes of the columns at the given index.
-
hasKeySet
boolean hasKeySet()
Required. `key_set` identifies the rows to be yielded. `key_set` names the primary keys of the rows in [table][google.spanner.v1.ReadRequest.table] to be yielded, unless [index][google.spanner.v1.ReadRequest.index] is present. If [index][google.spanner.v1.ReadRequest.index] is present, then [key_set][google.spanner.v1.ReadRequest.key_set] instead names index keys in [index][google.spanner.v1.ReadRequest.index]. If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order (if [index][google.spanner.v1.ReadRequest.index] is non-empty). If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is not empty, rows will be yielded in an unspecified order. It is not an error for the `key_set` to name rows that do not exist in the database. Read yields nothing for nonexistent rows.
.google.spanner.v1.KeySet key_set = 6 [(.google.api.field_behavior) = REQUIRED];
- Returns:
- Whether the keySet field is set.
-
getKeySet
KeySet getKeySet()
Required. `key_set` identifies the rows to be yielded. `key_set` names the primary keys of the rows in [table][google.spanner.v1.ReadRequest.table] to be yielded, unless [index][google.spanner.v1.ReadRequest.index] is present. If [index][google.spanner.v1.ReadRequest.index] is present, then [key_set][google.spanner.v1.ReadRequest.key_set] instead names index keys in [index][google.spanner.v1.ReadRequest.index]. If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order (if [index][google.spanner.v1.ReadRequest.index] is non-empty). If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is not empty, rows will be yielded in an unspecified order. It is not an error for the `key_set` to name rows that do not exist in the database. Read yields nothing for nonexistent rows.
.google.spanner.v1.KeySet key_set = 6 [(.google.api.field_behavior) = REQUIRED];
- Returns:
- The keySet.
-
getKeySetOrBuilder
KeySetOrBuilder getKeySetOrBuilder()
Required. `key_set` identifies the rows to be yielded. `key_set` names the primary keys of the rows in [table][google.spanner.v1.ReadRequest.table] to be yielded, unless [index][google.spanner.v1.ReadRequest.index] is present. If [index][google.spanner.v1.ReadRequest.index] is present, then [key_set][google.spanner.v1.ReadRequest.key_set] instead names index keys in [index][google.spanner.v1.ReadRequest.index]. If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order (if [index][google.spanner.v1.ReadRequest.index] is non-empty). If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is not empty, rows will be yielded in an unspecified order. It is not an error for the `key_set` to name rows that do not exist in the database. Read yields nothing for nonexistent rows.
.google.spanner.v1.KeySet key_set = 6 [(.google.api.field_behavior) = REQUIRED];
-
getLimit
long getLimit()
If greater than zero, only the first `limit` rows are yielded. If `limit` is zero, the default is no limit. A limit cannot be specified if `partition_token` is set.
int64 limit = 8;
- Returns:
- The limit.
-
getResumeToken
com.google.protobuf.ByteString getResumeToken()
If this request is resuming a previously interrupted read, `resume_token` should be copied from the last [PartialResultSet][google.spanner.v1.PartialResultSet] yielded before the interruption. Doing this enables the new read to resume where the last read left off. The rest of the request parameters must exactly match the request that yielded this token.
bytes resume_token = 9;
- Returns:
- The resumeToken.
-
getPartitionToken
com.google.protobuf.ByteString getPartitionToken()
If present, results will be restricted to the specified partition previously created using PartitionRead(). There must be an exact match for the values of fields common to this message and the PartitionReadRequest message used to create this partition_token.
bytes partition_token = 10;
- Returns:
- The partitionToken.
-
hasRequestOptions
boolean hasRequestOptions()
Common options for this request.
.google.spanner.v1.RequestOptions request_options = 11;
- Returns:
- Whether the requestOptions field is set.
-
getRequestOptions
RequestOptions getRequestOptions()
Common options for this request.
.google.spanner.v1.RequestOptions request_options = 11;
- Returns:
- The requestOptions.
-
getRequestOptionsOrBuilder
RequestOptionsOrBuilder getRequestOptionsOrBuilder()
Common options for this request.
.google.spanner.v1.RequestOptions request_options = 11;
-
getDataBoostEnabled
boolean getDataBoostEnabled()
If this is for a partitioned read and this field is set to `true`, the request will be executed via Spanner independent compute resources. If the field is set to `true` but the request does not set `partition_token`, the API will return an `INVALID_ARGUMENT` error.
bool data_boost_enabled = 15;
- Returns:
- The dataBoostEnabled.
