Cloud Bigtable Client - Class ReadModifyWriteRowRules (2.22.0)

Reference documentation and code samples for the Cloud Bigtable Client class ReadModifyWriteRowRules.

This is a builder class which builds read/modify/write rules specifying how the specified rows contents are to be transformed into writes. Entries are applied in order, meaning that earlier rules will affect the results of later ones. This is intended to be used in combination with Table::readModifyWriteRow() .

Appends the value to the existing value of the cell. If targeted cell is unset, it will be treated as containing the empty string.

Adds amount to the existing value. If the targeted cell is unset, it will be treated as containing a zero. Otherwise, the targeted cell must containt an 8-byte value (interpreted as a 64-bit big-endian signed integer), or the entire request will fail.

Returns proto representation of ReadModifyWriteRule.
