Detailed Description

A row which may only contain values for a subset of the columns.

This object contains a normal contiguous row, plus a bitfield indicating which columns have been set. Additionally, this type may optionally own copies of indirect data for variable length columns.

Constructor & Destructor Documentation

◆ KuduPartialRow() [1/2]

KuduPartialRow::KuduPartialRow ( const Schema *  schema)
explicit
Parameters
[in]schemaSchema to use for the row. The given Schema object must remain valid for the lifetime of this row.

◆ KuduPartialRow() [2/2]

KuduPartialRow::KuduPartialRow ( const KuduPartialRow &  other)

Create a copy of KuduPartialRow instance.

Parameters
[in]otherKuduPartialRow instance to copy from.

Member Function Documentation

◆ AllColumnsSet()

bool KuduPartialRow::AllColumnsSet ( ) const
Returns
true if all column values have been set.

◆ EncodeRowKey()

Status KuduPartialRow::EncodeRowKey ( std::string *  encoded_key) const

Encode a row key.

The result is suitable for use as a tablet split key, an encoded key range, etc.

Precondition
All of the key columns must be set.
Parameters
[out]encoded_keyThe encoded key (i.e. the result of the encoding).
Returns
Operation result status. In particular, this method returns InvalidArgument if not all the key columns are set.

◆ GetBinary() [1/2]

Get the string/binary/varchar value for a column by its name.

Parameters
[in]col_nameName of the column.
[out]valPointer to the placeholder to put the resulting value. Note that the method does not copy the value. Callers should copy the resulting Slice if necessary.

Status KuduPartialRow::SetString ( const Slice &  col_name,
const Slice &  val

Set the binary/string value for a column by name, copying the specified data immediately.

Note
The copying behavior is new for these methods starting Kudu 0.10. Prior to Kudu 0.10, these methods behaved like KuduPartialRow::SetStringNoCopy() and KuduPartialRow::SetBinaryNoCopy() correspondingly.
Parameters
[in]col_nameName of the target column.
[in]valThe value to set.
Returns
Operation result status.

◆ SetString() [2/2]

Status KuduPartialRow::SetString ( int  col_idx,
const Slice &  val 
)

Set the binary/string value for a column by index, copying the specified data immediately.

These setters are the same as the corresponding column-name-based setters, but with numeric column indexes. These are faster since they avoid hashmap lookups, so should be preferred in performance-sensitive code (e.g. bulk loaders).

Note
The copying behavior is new for these methods starting Kudu 0.10. Prior to Kudu 0.10, these methods behaved like KuduPartialRow::SetStringNoCopy() and KuduPartialRow::SetBinaryNoCopy() correspondingly.
Parameters
[in]col_idxThe index of the target column.
[in]valThe value to set.
Returns
Operation result status.

◆ SetStringCopy() [1/2]

Status KuduPartialRow::SetStringCopy ( const Slice &  col_name,
const Slice &  val 
)

Set the binary/string value for a column by name, copying the specified data immediately.

Note
The copying behavior is new for these methods starting Kudu 0.10. Prior to Kudu 0.10, these methods behaved like KuduPartialRow::SetStringNoCopy() and KuduPartialRow::SetBinaryNoCopy() correspondingly.
Parameters
[in]col_nameName of the target column.
[in]valThe value to set.
Returns
Operation result status.

◆ SetStringCopy() [2/2]

Status KuduPartialRow::SetStringCopy ( int  col_idx,
const Slice &  val

Parameters
[in]col_idxThe index of the target column.
[in]valThe value to set.
Returns
Operation result status.

◆ SetStringNoCopy() [1/2]

Status KuduPartialRow::SetStringNoCopy ( const Slice &  col_name,
const Slice &  val

[in]col_nameName of the target column.
[in]valThe value to set.
Returns
Operation result status.

◆ SetVarcharNoCopyUnsafe() [1/2]

Status KuduPartialRow::SetVarcharNoCopyUnsafe ( const Slice &  col_name,
const Slice &  val 
)

This method expects the values to be truncated already and they only do a basic validation that the data is not larger than the maximum column length (as indicated by the schema) multiplied by 4, as that's the upper limit if only 4-byte UTF8 characters are used. This is subject to change in the future.

Note
The specified data must remain valid until the corresponding RPC calls are completed to be able to access error buffers, if any errors happened (the errors can be fetched using the KuduSession::GetPendingErrors() method).
Warning
Unstable API
Parameters
[in]col_nameName of the target column.
[in]valThe value to set.
Returns
Operation result status.
