 | tags_on_failure | When a `kv` operation causes a runtime exception within the processor, the operation is safely stopped without crashing the processor, and the event is tagged with the provided tags. | If `tags_on_failure` is set to `["keyvalueprocessor_failure"]`, `{"tags": ["keyvalueprocessor_failure"]}` will be added to the event's metadata in the event of a runtime exception. |
 | value_grouping | Specifies whether to group values using predefined value grouping delimiters: `{...}`, `[...]', `<...>`, `(...)`, `"..."`, `'...'`, `http://... (space)`, and `https:// (space)`. If this flag is enabled, then the content between the delimiters is considered to be one entity and is not parsed for key-value pairs. Default is `false`. If `value_grouping` is `true`, then `{"key1=[a=b,c=d]&key2=value2"}` parses to `{"key1": "[a=b,c=d]", "key2": "value2"}`. |
 | drop_keys_with_no_value | Specifies whether keys should be dropped if they have a null value. Default is `false`. If `drop_keys_with_no_value` is set to `true`, then `{"key1=value1&key2"}` parses to `{"key1": "value1"}`. |
+| strict_grouping | Specifies whether strict grouping should be enabled when the `value_grouping` or `string_literal_character` options are used. Default is `false`. | When enabled, groups with unmatched end characters yield errors. The event is ignored after the errors are logged. |
+| string_literal_character | Can be set to either a single quotation mark (`'`) or a double quotation mark (`"`). Default is `null`. | When this option is used, any text contained within the specified quotation mark character will be ignored and excluded from key-value parsing. For example, `text1 "key1=value1" text2 key2=value2` would parse to `{"key2": "value2"}`. | 
+| key_value_when | Allows you to specify a [conditional expression](https://opensearch.org/docs/latest/data-prepper/pipelines/expression-syntax/), such as `/some-key == "test"`, that will be evaluated to determine whether the processor should be applied to the event. |
