STREAMING_STREAM(1)

cursor

Description

A cursor that indicates the position in the stream from which you want to begin consuming messages and which is required by the GetMessages <https://docs.cloud.oracle.com/en-us/iaas/tools/oci-cli/latest/oci_cli_docs/cmdref/streaming/stream/message/get.html> operation.

Available Commands

create-cursor
create-group-cursor

create-cursor

Description
Usage
Required Parameters
Optional Parameters

UTC with microseconds
Timezone with microseconds

Global Parameters
Examples

Description

Creates a cursor. Cursors are used to consume a stream, starting from a specific point in the partition and going forward from there. You can create a cursor based on an offset, a time, the trim horizon, or the most recent message in the stream. As the oldest message inside the retention period boundary, using the trim horizon effectively lets you consume all messages in the stream. A cursor based on the most recent message allows consumption of only messages that are added to the stream after you create the cursor. Cursors expire five minutes after you receive them from the service.

The top level –endpoint parameter must be supplied for this operation.

Usage

oci streaming stream cursor create-cursor [OPTIONS]

Required Parameters

--partition [text]

The partition to get messages from.

--stream-id [text]

The OCID of the stream.

--type [text]

The type of cursor, which determines the starting point from which the stream will be consumed:

•: AFTER_OFFSET: The partition position immediately following the offset you specify. (Offsets are assigned when you successfully append a message to a partition in a stream.) - AT_OFFSET: The exact partition position indicated by the offset you specify. - AT_TIME: A specific point in time. - LATEST: The most recent message in the partition that was added after the cursor was created. - TRIM_HORIZON: The oldest message in the partition that is within the retention period window.

Accepted values are:

AFTER_OFFSET, AT_OFFSET, AT_TIME, LATEST, TRIM_HORIZON

Optional Parameters

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--offset [integer]

The offset to consume from if the cursor type is AT_OFFSET or AFTER_OFFSET.

--time [datetime]

The time to consume from if the cursor type is AT_TIME, expressed in RFC 3339 <https://tools.ietf.org/rfc/rfc3339> timestamp format.

message

Description

A message in a stream.

Available Commands

get

Description
Usage
Required Parameters
Optional Parameters
Global Parameters
Examples

Description

Returns messages from the specified stream using the specified cursor as the starting point for consumption. By default, the number of messages returned is undefined, but the service returns as many as possible. To get messages, you must first obtain a cursor using the CreateCursor <https://docs.cloud.oracle.com/en-us/iaas/tools/oci-cli/latest/oci_cli_docs/cmdref/streaming/stream/cursor/create-cursor.html> operation. In the response, retrieve the value of the ‘opc-next-cursor’ header to pass as a parameter to get the next batch of messages in the stream.

The top level –endpoint parameter must be supplied for this operation.

Usage

oci streaming stream message get [OPTIONS]

Required Parameters

--cursor [text]

The cursor used to consume the stream.

--stream-id [text]

The OCID of the stream.

Optional Parameters

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--limit [integer]

The maximum number of messages to return. You can specify any value up to 10000. By default, the service returns as many messages as possible. Consider your average message size to help avoid exceeding throughput on the stream.

Global Parameters

Use oci --help for help on global parameters.

put

Description
Usage
Required Parameters
Optional Parameters
Global Parameters
Examples

Description

Emits messages to a stream. There’s no limit to the number of messages in a request, but the total size of a message or request must be 1 MiB or less. The service calculates the partition ID from the message key and stores messages that share a key on the same partition. If a message does not contain a key or if the key is null, the service generates a message key for you. The partition ID cannot be passed as a parameter.

The top level –endpoint parameter must be supplied for this operation.

Usage

oci streaming stream message put [OPTIONS]

Required Parameters

--messages [complex type]

The array of messages to put into a stream. Must be Base64 encoded. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--stream-id [text]

The OCID of the stream.

Optional Parameters

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.
