Instance Constructors

  1. new S3AttributeStore(bucket: String, prefix: String, s3Client: ⇒ S3Client = S3ClientProducer.get())

    bucket

    S3 bucket to use for attribute store

    prefix

    path in the bucket for given LayerId

Value Members

  1. def attributePath(id: LayerId, attributeName: String): String
  2. def attributePrefix(attributeName: String): String

  4. def availableZoomLevels(layerName: String): Seq[Int]

    Return a sequence of available zoom levels for a named layer.

    Return a sequence of available zoom levels for a named layer.

    This function should be re-implemented by AttributeStore subclasses so that catalogs with large numbers of layers can be queried efficiently.

    NOTE: S3 is eventually consistent, therefore it is possible to write an attribute and fail to read it immediately afterwards.

    NOTE: S3 is eventually consistent, therefore it is possible to write an attribute and fail to read it immediately afterwards. It is not clear if this is a practical concern. It could be remedied by some kind of time-out cache for both read/write in this class.
