| Client Service | gridfs-client-service | | Controller Service API:
MongoDBClientService
Implementation: MongoDBControllerService | The MongoDB client service to use for database connections. |
| Mongo Database Name | gridfs-database-name | | | The name of the database to use
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Bucket Name | gridfs-bucket-name | | | The GridFS bucket where the files will be stored. If left blank, it will use the default value 'fs' that the MongoDB client driver uses.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| File Name | gridfs-file-name | | | The name of the file in the bucket that is the target of this processor. GridFS file names do not include path information because GridFS does not sort files into folders within a bucket.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| File Properties Prefix | putgridfs-properties-prefix | | | Attributes that have this prefix will be added to the file stored in GridFS as metadata.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Enforce Uniqueness | putgridfs-enforce-uniqueness | None | | When enabled, this option will ensure that uniqueness is enforced on the bucket. It will do so by creating a MongoDB index that matches your selection. It should ideally be configured once when the bucket is created for the first time because it could take a long time to build on an existing bucket wit a lot of data. |
| Hash Attribute | putgridfs-hash-attribute | hash.value | | If uniquness enforcement is enabled and the file hash is part of the constraint, this must be set to an attribute that exists on all incoming flowfiles.
Supports Expression Language: true (will be evaluated using variable registry only) |
| Chunk Size | putgridfs-chunk-size | 256 KB | | Controls the maximum size of each chunk of a file uploaded into GridFS.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
