About
This module defines a producer/consumer pattern and uses the Log features provided by Nuxeo Stream.
Producer/Consumer pattern with automation operations
The Log is used to perform mass import.
It decouples the Extraction/Transformation from the Load (using the ETL terminology).
The extraction and transformation is done by a document message producer with custom logic.
This module comes with a random document and a random blob generator, that does the same job as the random importer of the
nuxeo-importer-coremodule.The load into Nuxeo is done with a generic consumer.
Automation operations are exposed to run producers and consumers.
Two steps import: Generate and Import documents with blobs
- Run a random producers of document messages, these message represent Folder and File document a blob. The total number of document created is:
nbThreads * nbDocuments.
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runRandomDocumentProducers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"nbDocuments": 100, "nbThreads": 5}}'Params Default Description nbDocumentsThe number of documents to generate per producer thread nbThreads8The number of concurrent producer to run avgBlobSizeKB1The average blob size fo each file documents in KB.

- Run producers of random blob messages
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runRandomBlobProducers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"nbBlobs": 100, "nbThreads": 5}}'Params Default Description nbBlobsThe number of blobs to generate per producer thread nbThreads8The number of concurrent producer to run avgBlobSizeKB1The average blob size fo each file documents in KB langen_USThe locale used for the generated content, can be "fr_FR" or "en_US" logNameimport/blobThe name of the Log to append blobs. logSize$nbThreadsThe number of partitions in the Log which will fix the maximum number of consumer threads - Run consumers of blob messages importing into the Nuxeo binary store, saving blob information into a new Log.
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runBlobConsumers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"blobProviderName": "default", "logBlobInfo": "blob-info"}}'Params Default Description blobProviderNamedefaultThe name of the binary store blob provider logNameimport/blobThe name of the Log that contains the blob logBlobInfoimport/blob-infoThe name of the Log to append blob information about imported blobs nbThreads$logSizeThe number of concurrent consumer, should not be greater than the number of partitions in the Log retryMax3Number of time a consumer retry to import in case of failure retryDelayS2Delay between retries - Run producers of random Nuxeo document messages which use produced blobs created in step 2
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runRandomDocumentProducers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"nbDocuments": 200, "nbThreads": 5, "logBlobInfo": "blob-info"}}'Same params listed in the previous previous runRandomDocumentProducers call, here we set the
logBlobInfoparameter.- Run consumers of document messages
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runDocumentConsumers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"rootFolder": "/default-domain/workspaces"}}'Same params listed in the previous previous runDocumentConsumers call.
Create blobs using existing files
Create a file containing the list of files to import then:
- Generate blob messages corresponding to the files, dispatch the messages into 4 partitions:
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runFileBlobProducers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"listFile": "/tmp/my-file-list.txt", "logSize": 4}}'Params Default Description listFileThe path to the listing file basePath'' The base path to use as prefix of each file listed in the listFilenbBlobs0 The number of blobs to generate per producer thread, 0 means all entries, loop on listFileentries if necessarynbThreads1The number of concurrent producer to run logNameimport/blobThe name of the Log to append blobs. logSize$nbThreadsThe number of partitions in the Log which will fix the maximum number of consumer threads The you can use the 3 others steps describes the above section to import blobs with 4 threads and create documents.
Note that the type of document will be adapted to the detected mime type of the file so that
- image file will generate a
Picturedocument - video file will generate a
Videodocument - other type will be translated to
Filedocument
Generate random file for testing purpose
For testing purpose it can be handy to generate different file from an existing one, the goal is to generate lots of unique files with a limited set of files.
To do this you need to first generates blob messages pointing to file (see previous section) and choose the
nbBlobscorresponding to the expected number of blob to import, (use a greater number that the existing files).The next step is to add some special option to blob consumer so that instead of importing the existing file, a watermark will be added to the blob before importing it.
- Run consumers of blob messages adding watermark to file and importing into the Nuxeo binary store, saving blob information into a new Log.
curl -X POST 'http://localhost:8080/nuxeo/site/automation/StreamImporter.runBlobConsumers' -u Administrator:Administrator -H 'content-type: application/json' \ -d '{"params":{"watermark": "foo"}}'The additional parameters are:
Params Default Description watermarkAsk to add a watermark to the file before importing it, use the provided string if possible. persistBlobPathUse a path if you want to keep the generated files on disk blobProviderNamedefaultIf blank there is no Nuxeo blob import Continue with other steps described above to generate and create documents.
Note that only few mime type are supported for watermark so far:
text/plain: Insert a uniq tag at the beginning of text.image/jpeg: Set the exif software tag to a uniq tag.video/mp4: Set the title with the uniq tag.
