       *   `:upload_protocol` (*type:* `String.t`) - Upload protocol for media (e.g. "raw", "multipart").
-      *   `:filter` (*type:* `String.t`) - An expression that filters the list of returned operations. A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: `<`, `>`, `<=`, `>=`, `!=`, `=`, or `:`. Colon `:` is the contains operator. Filter rules are not case sensitive. The following fields in the Operation are eligible for filtering: * `name` - The name of the long-running operation * `done` - False if the operation is in progress, else true. * `metadata.@type` - the type of metadata. For example, the type string for RestoreDatabaseMetadata is `type.googleapis.com/google.spanner.admin.database.v1.RestoreDatabaseMetadata`. * `metadata.` - any field in metadata.value. `metadata.@type` must be specified first, if filtering on metadata fields. * `error` - Error associated with the long-running operation. * `response.@type` - the type of response. * `response.` - any field in response.value. You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic. However, you can specify AND, OR, and NOT logic explicitly.

It is possible that the last value in values is "chunked", meaning that the rest of the value is sent in subsequent `PartialResultSet`(s). This is denoted by the chunked_value field. Two or more chunked values can be merged to form a complete value as follows: * `bool/number/null`: cannot be chunked * `string`: concatenate the strings * `list`: concatenate the lists. If the last element in a list is a `string`, `list`, or `object`, merge it with the first element in the next list by applying these rules recursively. * `object`: concatenate the (field name, field value) pairs. If a field name is duplicated, then apply these rules recursively to merge the field values. Some examples of merging: # Strings are concatenated. "foo", "bar" => "foobar" # Lists of non-strings are concatenated. [2, 3], [4] => [2, 3, 4] # Lists are concatenated, but the last and first elements are merged # because they are strings. ["a", "b"], ["c", "d"] => ["a", "bc", "d"] # Lists are concatenated, but the last and first elements are merged # because they are lists. Recursively, the last and first elements # of the inner lists are merged because they are strings.

The following `PartialResultSet`s might be yielded: { "metadata": { ... } "values": ["Hello", "W"] "chunked_value": true "resume_token": "Af65..." } { "values": ["orl"] "chunked_value": true } { "values": ["d"] "resume_token": "Zx1B..." } This sequence of `PartialResultSet`s encodes two rows, one containing the field value `"Hello"`, and a second containing the field value `"World" = "W" + "orl" + "d"`. Not all `PartialResultSet`s contain a `resume_token`. Execution can only be resumed from a previously yielded `resume_token`. For the above sequence of `PartialResultSet`s, resuming the query with `"resume_token": "Af65..."` will yield results from the `PartialResultSet` with value `["orl"]`.
