File Naming Scheme (file_naming_scheme)

Environment variable: TARGET_YAML_FILE_NAMING_SCHEME

The scheme with which output files will be named. Naming scheme may leverage any of the following substitutions:

{stream_name}
{datestamp}
{timestamp}

Configure this setting directly using the following Meltano command:

meltano config target-yaml set file_naming_scheme [value]

Datestamp Format (datestamp_format)

Environment variable: TARGET_YAML_DATESTAMP_FORMAT

A python format string to use when outputting the {datestamp} string. For reference, see - https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes

Configure this setting directly using the following Meltano command:

meltano config target-yaml set datestamp_format [value]

Timestamp Format (timestamp_format)

Environment variable: TARGET_YAML_TIMESTAMP_FORMAT

A python format string to use when outputting the {datestamp} string. For reference, see - https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes

Configure this setting directly using the following Meltano command:

meltano config target-yaml set timestamp_format [value]

Timestamp Timezone (timestamp_timezone)

Environment variable: TARGET_YAML_TIMESTAMP_TIMEZONE

The timezone code or name to use when generating {timestamp} and {datestamp}. Defaults to "UTC". For a list of possible values, please see -https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

Configure this setting directly using the following Meltano command:

meltano config target-yaml set timestamp_timezone [value]

Stream Maps (stream_maps)

Environment variable: TARGET_YAML_STREAM_MAPS

Allows inline stream transformations and aliasing. For more information see - https://sdk.meltano.com/en/latest/stream_maps.html

Configure this setting directly using the following Meltano command:

meltano config target-yaml set stream_maps [value]

Record Insert Jsonpath (record_insert_jsonpath)

Environment variable: TARGET_YAML_RECORD_INSERT_JSONPATH

A jsonpath string determining the insertion point for new records. Currently, this must be the path to a map key which will be populated by a list of records. For example "$.metrics" will populate the file with metrics - [{<record1>},{<record2>},...] For JSONPath syntax help, see - https://jsonpath.com

Configure this setting directly using the following Meltano command:

meltano config target-yaml set record_insert_jsonpath [value]

Record Key Property Name (record_key_property_name)

Environment variable: TARGET_YAML_RECORD_KEY_PROPERTY_NAME

A property in the record which will be used as the dictionary key. If this property is provided, records will be written as key-value objects; if omitted, records are written as a list.

Configure this setting directly using the following Meltano command:

meltano config target-yaml set record_key_property_name [value]

Record Sort Property Name (record_sort_property_name)

Environment variable: TARGET_YAML_RECORD_SORT_PROPERTY_NAME

A property in the record which will be used as a sort key. If this property is omitted, records will not be sorted.

Configure this setting directly using the following Meltano command:

meltano config target-yaml set record_sort_property_name [value]

Overwrite Behavior (overwrite_behavior)

Environment variable: TARGET_YAML_OVERWRITE_BEHAVIOR

Determines the overwrite behavior if destination file already exists. Must be one of the following string values:

append_records (default): append records at the insertion point
replace_records: replace all records at the insertion point
replace_file: replace entire file using default_yaml_template

Configure this setting directly using the following Meltano command:

meltano config target-yaml set overwrite_behavior [value]

Default Yaml Template (default_yaml_template)

Environment variable: TARGET_YAML_DEFAULT_YAML_TEMPLATE

Text string to use for a yaml template file. This text will be used to create a new file if the destination file does not exist.

Configure this setting directly using the following Meltano command:

meltano config target-yaml set default_yaml_template [value]
