ImportMessages

rpc ImportMessages(ImportMessagesRequest) returns (Operation)

Import messages to the HL7v2 store by loading data from the specified sources. This method is optimized to load large quantities of data using import semantics that ignore some HL7v2 store configuration options and are not suitable for all use cases. It is primarily intended to load data into an empty HL7v2 store that is not being used by other clients.

An existing message will be overwritten if a duplicate message is imported. A duplicate message is a message with the same raw bytes as a message that already exists in this HL7v2 store. When a message is overwritten, its labels will also be overwritten.

The import operation is idempotent unless the input data contains multiple valid messages with the same raw bytes but different labels. In that case, after the import completes, the store contains exactly one message with those raw bytes but there is no ordering guarantee on which version of the labels it has. The operation result counters do not count duplicated raw bytes as an error and count one success for each message in the input, which might result in a success count larger than the number of messages in the HL7v2 store.

If some messages fail to import, for example due to parsing errors, successfully imported messages are not rolled back.

This method returns an Operation that can be used to track the status of the import by calling GetOperation.

Immediate fatal errors appear in the error field, errors are also logged to Cloud Logging (see Viewing error logs in Cloud Logging). Otherwise, when the operation finishes, a response of type ImportMessagesResponse is returned in the response field. The metadata field type for this operation is OperationMetadata.

  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Authentication Overview.
IngestMessage

rpc IngestMessage(IngestMessageRequest) returns (IngestMessageResponse)

Parses and stores an HL7v2 message. This method triggers an asynchronous notification to any Pub/Sub topic configured in Hl7V2Store.Hl7V2NotificationConfig, if the filtering matches the message. If an MLLP adapter is configured to listen to a Pub/Sub topic, the adapter transmits the message when a notification is received. If the method is successful, it generates a response containing an HL7v2 acknowledgment (ACK) message. If the method encounters an error, it returns a negative acknowledgment (NACK) message. This behavior is suitable for replying to HL7v2 interface systems that expect these acknowledgments.

Authorization scopes

start_time

Timestamp

The start of the range in send_time (MSH.7, https://www.hl7.org/documentcenter/public_temp_2E58C1F9-1C23-BA17-0C6126475344DA9D/wg/conf/HL7MSH.htm) to process. If not specified, the UNIX epoch (1970-01-01T00:00:00Z) is used.

This value has to come before the end_time defined below. Only messages whose send_time lies in the range start_time (inclusive) to end_time (exclusive) are exported.
end_time

Timestamp

The end of the range in send_time (MSH.7, https://www.hl7.org/documentcenter/public_temp_2E58C1F9-1C23-BA17-0C6126475344DA9D/wg/conf/HL7MSH.htm) to process. If not specified, the time when the export is scheduled is used.

This value has to come after the start_time defined below. Only messages whose send_time lies in the range start_time (inclusive) to end_time (exclusive) are exported.
filter

string

Restricts messages exported to those matching a filter, only applicable to PubsubDestination and GcsDestination. The following syntax is available:

  • A string field value can be written as text inside quotation marks, for example "query text". The only valid relational operation for text fields is equality (=), where text is searched within the field, rather than having the field be equal to the text. For example, "Comment = great" returns messages with great in the comment field.
  • A number field value can be written as an integer, a decimal, or an exponential. The valid relational operators for number fields are the equality operator (=), along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • A date field value must be written in the yyyy-mm-dd format. Fields with date and time use the RFC3339 time format. Leading zeros are required for one-digit months and days. The valid relational operators for date fields are the equality operator (=) , along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • Multiple field query expressions can be combined in one query by adding AND or OR operators between the expressions. If a boolean operator appears within a quoted string, it is not treated as special, and is just another part of the character string to be matched. You can prepend the NOT operator to an expression to negate it.

The following fields and functions are available for filtering:

  • message_type, from the MSH-9.1 field. For example, NOT message_type = "ADT".
  • send_date or sendDate, the YYYY-MM-DD date the message was sent in the dataset's time_zone, from the MSH-7 segment. For example, send_date < "2017-01-02".
  • send_time, the timestamp when the message was sent, using the RFC3339 time format for comparisons, from the MSH-7 segment. For example, send_time < "2017-01-02T00:00:00-05:00".
  • create_time, the timestamp when the message was created in the HL7v2 store. Use the RFC3339 time format for comparisons. For example, create_time < "2017-01-02T00:00:00-05:00".
  • send_facility, the care center that the message came from, from the MSH-4 segment. For example, send_facility = "ABC".

Note: The filter will be applied to every message in the HL7v2 store whose send_time lies in the range defined by the start_time and the end_time. Even if the filter only matches a small set of messages, the export operation can still take a long time to finish when a lot of messages are between the specified start_time and end_time range.
Union field destination. Export destination. destination can be only one of the following:
gcs_destination

GcsDestination

Export to a Cloud Storage destination.
pubsub_destination

PubsubDestination

CONTENT_STRUCTURE_UNSPECIFIED If the content structure is not specified, the default value MESSAGE_JSON will be used.
MESSAGE_JSON Messages are printed using the JSON format returned from the GetMessage API. Messages are delimited with newlines.

GcsSource

Specifies the configuration for importing data from Cloud Storage.

Fields
uri

string

Points to a Cloud Storage URI containing file(s) to import.

The URI must be in the following format: gs://{bucket_id}/{object_id}. The URI can include wildcards in object_id and thus identify multiple files. Supported wildcards:

  • * to match 0 or more non-separator characters
  • ** to match 0 or more characters (including separators). Must be used at the end of a path and with no other wildcards in the path. Can also be used with a file extension (such as .ndjson), which imports all files with the extension in the specified directory and its sub-directories. For example, gs://my-bucket/my-directory/**.ndjson imports all files with .ndjson extensions in my-directory/ and its sub-directories.
  • ? to match 1 character

Files matching the wildcard are expected to contain content only, no metadata.

parser_config

ParserConfig

The configuration for the parser. It determines how the server parses the messages.
labels

map<string, string>

User-supplied key-value pairs used to organize HL7v2 stores.

Label values are optional, must be between 1 and 63 characters long, have a UTF-8 encoding of maximum 128 bytes, and must conform to the following PCRE regular expression: [\p{Ll}\p{Lo}\p{N}_-]{0,63}

No more than 64 labels can be associated with a given store.
notification_configs[]

Hl7V2NotificationConfig

A list of notification configs. Each configuration uses a filter to determine whether to publish a message (both Ingest & Create) on the corresponding notification destination. Only the message name is sent as part of the notification. Supplied by the client.
reject_duplicate_message

bool

Determines whether to reject duplicate messages. A duplicate message is a message with the same raw bytes as a message that has already been ingested/created in this HL7v2 store. The default value is false, meaning that the store accepts the duplicate messages and it also returns the same ACK message in the IngestMessageResponse as has been returned previously. Note that only one resource is created in the store. When this field is set to true, CreateMessage/IngestMessage requests with a duplicate message will be rejected by the store, and IngestMessageErrorDetail returns a NACK message upon rejection.

Hl7V2NotificationConfig

Specifies where and whether to send notifications upon changes to a data store.

Fields
pubsub_topic

string

The Pub/Sub topic that notifications of changes are published on. Supplied by the client. The notification is a PubsubMessage with the following fields:

  • PubsubMessage.Data contains the resource name.
  • PubsubMessage.MessageId is the ID of this notification. It is guaranteed to be unique within the topic.
  • PubsubMessage.PublishTime is the time when the message was published.

Note that notifications are only sent if the topic is non-empty. Topic names must be scoped to a project. Cloud Healthcare API service account must have publisher permissions on the given Pub/Sub topic. Not having adequate permissions causes the calls that send notifications to fail.

If a notification can't be published to Pub/Sub, errors are logged to Cloud Logging. For more information, see Viewing error logs in Cloud Logging.
filter

string

Restricts notifications sent for messages matching a filter. If this is empty, all messages are matched. The following syntax is available:

  • A string field value can be written as text inside quotation marks, for example "query text". The only valid relational operation for text fields is equality (=), where text is searched within the field, rather than having the field be equal to the text. For example, "Comment = great" returns messages with great in the comment field.
  • A number field value can be written as an integer, a decimal, or an exponential. The valid relational operators for number fields are the equality operator (=), along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • A date field value must be written in yyyy-mm-dd form. Fields with date and time use the RFC3339 time format. Leading zeros are required for one-digit months and days. The valid relational operators for date fields are the equality operator (=) , along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • Multiple field query expressions can be combined in one query by adding AND or OR operators between the expressions. If a boolean operator appears within a quoted string, it is not treated as special, it's just another part of the character string to be matched. You can prepend the NOT operator to an expression to negate it.

Fields/functions available for filtering are:

  • message_type, from the MSH-9.1 field. For example, NOT message_type = "ADT".
  • send_date or sendDate, the YYYY-MM-DD date the message was sent in the dataset's time_zone, from the MSH-7 segment. For example, send_date < "2017-01-02".
  • send_time, the timestamp when the message was sent, using the RFC3339 time format for comparisons, from the MSH-7 segment. For example, send_time < "2017-01-02T00:00:00-05:00".
  • create_time, the timestamp when the message was created in the HL7v2 store. Use the RFC3339 time format for comparisons. For example, create_time < "2017-01-02T00:00:00-05:00".
  • send_facility, the care center that the message came from, from the MSH-4 segment. For example, send_facility = "ABC".
  • PatientId(value, type), which matches if the message lists a patient having an ID of the given value and type in the PID-2, PID-3, or PID-4 segments. For example, PatientId("123456", "MRN").
  • labels.x, a string value of the label with key x as set using the Message.labels map. For example, labels."priority"="high". The operator :* can be used to assert the existence of a label. For example, labels."priority":*.

For example, "Comment = great" returns messages with great in the comment field.
  • A number field value can be written as an integer, a decimal, or an exponential. The valid relational operators for number fields are the equality operator (=), along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • A date field value must be written in yyyy-mm-dd form. Fields with date and time use the RFC3339 time format. Leading zeros are required for one-digit months and days. The valid relational operators for date fields are the equality operator (=) , along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • Multiple field query expressions can be combined in one query by adding AND or OR operators between the expressions. If a boolean operator appears within a quoted string, it is not treated as special, it's just another part of the character string to be matched. You can prepend the NOT operator to an expression to negate it.

Fields/functions available for filtering are:

  • message_type, from the MSH-9.1 field. For example, NOT message_type = "ADT".
  • send_date or sendDate, the YYYY-MM-DD date the message was sent in the dataset's time_zone, from the MSH-7 segment. For example, send_date < "2017-01-02".
  • send_time, the timestamp when the message was sent, using the RFC3339 time format for comparisons, from the MSH-7 segment. For example, send_time < "2017-01-02T00:00:00-05:00".
  • create_time, the timestamp when the message was created in the HL7v2 store. Use the RFC3339 time format for comparisons. For example, create_time < "2017-01-02T00:00:00-05:00".
  • send_facility, the care center that the message came from, from the MSH-4 segment. For example, send_facility = "ABC".
  • PatientId(value, type), which matches if the message lists a patient having an ID of the given value and type in the PID-2, PID-3, or PID-4 segments. For example, PatientId("123456", "MRN").
  • labels.x, a string value of the label with key x as set using the Message.labels map. For example, labels."priority"="high". The operator :* can be used to assert the existence of a label. For example, labels."priority":*.

V2 The parsed_data includes every given non-empty message field.
V3

This version is the same as V2, with the following change.

The parsed_data contains unescaped escaped field separators, component separators, sub-component separators, repetition separators, escape characters, and truncation characters.

If schema is specified, the schematized parser uses improved parsing heuristics compared to previous versions.
