6.2. Specific Driver configurations

Warning

Note for S3 that maxPartSizeForUnknownLength or driverMaxChunkSize should be defined according to memory available and concurrent access, as each transfer (upload or download) could lead to one buffer of this size for each.

Driver for S3 Service Configuration

Property/Yaml property	Possible Values
ccs.driver.s3.host	S3 Host (do not use quarkus.s3.endpoint-override)
ccs.driver.s3.keyId	S3 KeyId (do not use quarkus.s3.aws.credentials.static-provider.access-key-id nor aws.accessKeyId)
ccs.driver.s3.key	S3 Key (do not use quarkus.s3.aws.credentials.secret-access-key nor aws.secretAccessKey)
ccs.driver.s3.region	S3 Region (do not use quarkus.s3.aws.region)
ccs.driver.s3.maxPartSize	MultiPart size (minimum 5 MB, maximum 5 GB, default 256 MB)
ccs.driver.s3.maxPartSizeForUnknownLength	512 MB as in ccs.driverMaxChunkSize, MultiPart size (minimum 5 MB, maximum ~2 GB): will be used to buffer InputStream if length is unknown, so take care of the Memory consumption associated (512 MB, default, will limit the total InputStream length to 5 TB since 10K parts)

Driver for Azure Blob Storage Service Configuration

Property/Yaml property	Possible Values
quarkus.azure.storage.blob.connection-string	Connection String to Azure Blob Storage (see https://docs.quarkiverse.io/quarkus-azure-services/dev/index.html)
ccs.driver.azure.maxConcurrency	2, Maximum concurrency in upload/download with Azure Blob Storage
ccs.driver.azure.maxPartSize	256 MB, MultiPart size (minimum 5 MB, maximum 4 GB, default 256 MB)
ccs.driver.azure.maxPartSizeForUnknownLength	512 MB as in ccs.driverMaxChunkSize, MultiPart size (minimum 5 MB, maximum ~2 GB): will be used to buffer InputStream if length is unknown (no memory impact)

Driver for Google Cloud Storage Service Configuration

Property/Yaml property	Possible Values
quarkus.google.cloud.project-id	Project Id in Google Cloud (and related Authentication see https://docs.quarkiverse.io/quarkus-google-cloud-services/main/index.html)
ccs.driver.google.disableGzip	true, Default is to use Gzip content, but may be disabled (default: true so disabled)
ccs.driver.google.maxPartSize	256 MB, MultiPart size (minimum 5 MB, maximum 4 GB, default 256 MB) (Property ignored)
ccs.driver.google.maxBufSize	128 MB; MultiPart size (minimum 5 MB, maximum ~2 GB): will be used to buffer InputStream if length is unknown (no memory impact)
