OCI Object Storage Enqueue and Dequeue
Enqueue
Enqueueing from OCI Object Storage is quite similar to File Enqueue except that the MessageSource is defined differently. For example:
<
MessageSource
>
<
ValueChainId
>9123</
ValueChainId
>
<
Name
>OCIObjectStorageInbox</
Name
>
<
SourceType
>OCIObjectStorage</
SourceType
>
<
Config
>{ accessKey: 'MyAccessKey', secretKey: 'MySecretKey', namespace: 'MyNamespaceName', bucketName: 'MyBucketName', rootDir: '/my/polleddir', region:'us-phoenix-1' }</
Config
>
</
MessageSource
>
Dequeue
Dequeuing to OCI Object Storage is quite similar to Dequeue to file except for the MessageDestination specification.
A MessageDestination of DestinationType OCIObjectStorage is used to configure the final destination for a message being dequeued to OCI Object Storage. For example:
<
MessageDestination
>
<
ValueChainId
>9123</
ValueChainId
>
<
Name
>OCIObjectStorageDestination</
Name
>
<
DestinationType
>OCIObjectStorage</
DestinationType
>
<
Config
>{accessKey: 'MyAccessKey', secretKey: 'MySecretKey', namespace: 'MyNamespaceName', bucketName: 'MyBucketName', rootDir: '/my/destdir', region:'us-phoenix-1', fileNamePattern: '%{FileName}'}</
Config
>
</
MessageDestination
>
The Config is a JSON object containing:
JSON Objects |
Required/Optional |
Description |
accessKey |
Required |
Access key is provided by OCI Object Storage administrator. |
secretKey |
Required |
Secret key is provided by OCI Object Storage administrator. |
namespace |
Required |
Namespace name under which storage is created. |
bucketName |
Required |
Bucket name provided by OCI Object Storage administrator. |
rootDir |
Required |
Directory in OCI Object Storage which needs to be polled or in which file needs to be stored. |
region |
Required |
OCI Object Storage region. |
compressed |
Optional |
True to decompress the file while polling or compress while sending the file to OCI Object Storage. |
fileNamePattern |
Optional |
fileNamePattern is an optional file name substitution pattern used when dequeuing messages in the OCI Object Storage i.e. %{fileName}.csv. |
fileNamer |
Optional |
As an alternative to fileNamePattern, you can provide a fileNamer. Here you should give a groovy expression that evaluates to the desired value of the file name. The com.onenetwork.platform.integ.msg.Message being dequeued will be bound under the name msg so you can use things like interface name, client file name, etc. to help you generate the final file name. Example: fileNamer: 'msg.getOutboundInterface() + "." + System.currentTimeMillis() + ".csv" ' or fileNamer: ' if ( "ZBKS.BookLoad" .equals(msg.getOutboundInterface())) { msg.getOutboundInterface() + "." + System.currentTimeMillis() + ".csv" } else { resolvedFileName }' |
tempFileNamePattern |
Optional |
Same as of fileNamePattern except if provided, the file will be first streamed to the temp file name and then renamed to fileNamePattern. |
