clearIndex()

public ReadRequest.Builder clearIndex()

If non-empty, the name of an index on table. This index is used instead of the table primary key when interpreting key_set and sorting result rows. See key_set for further information.

ReadRequest.Builder

This builder for chaining.

clearKeySet()

public ReadRequest.Builder clearKeySet()

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index. If the partition_token field is empty, rows are yielded in table primary key order (if index is empty) or index key order (if index is non-empty).
