    • Method Detail

      • recordSizeKiB

        public final Integer recordSizeKiB()

        Specifies the record size of an OpenZFS root volume, in kibibytes (KiB). Valid values are 4, 8, 16, 32, 64, 128, 256, 512, or 1024 KiB. The default is 128 KiB. Most workloads should use the default record size. Database workflows can benefit from a smaller record size, while streaming workflows can benefit from a larger record size. For additional guidance on setting a custom record size, see Tips for maximizing performance in the Amazon FSx for OpenZFS User Guide.

        Returns:

      • dataCompressionType

        public final OpenZFSDataCompressionType dataCompressionType()

        Specifies the method used to compress the data on the volume. The compression type is NONE by default.

        • NONE - Doesn't compress the data on the volume. NONE is the default.

        • ZSTD - Compresses the data in the volume using the Zstandard (ZSTD) compression algorithm. Compared to LZ4, Z-Standard provides a better compression ratio to minimize on-disk storage utilization.

        • LZ4 - Compresses the data in the volume using the LZ4 compression algorithm. Compared to Z-Standard, LZ4 is less compute-intensive and delivers higher write throughput speeds.

        If the service returns an enum value that is not available in the current SDK version, dataCompressionType will return OpenZFSDataCompressionType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from dataCompressionTypeAsString().

        Returns:
        Specifies the method used to compress the data on the volume. The compression type is NONE by default.

        • NONE - Doesn't compress the data on the volume. NONE is the default.

      • dataCompressionTypeAsString

        public final String dataCompressionTypeAsString()

        Specifies the method used to compress the data on the volume. The compression type is NONE by default.

        • NONE - Doesn't compress the data on the volume. NONE is the default.

      • hasNfsExports

        public final boolean hasNfsExports()
        For responses, this returns true if the service returned a value for the NfsExports property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • nfsExports

        public final List<OpenZFSNfsExport> nfsExports()

        The configuration object for mounting a file system.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasNfsExports() method.

        Returns:
        The configuration object for mounting a file system.

      • hasUserAndGroupQuotas

        public final boolean hasUserAndGroupQuotas()
        For responses, this returns true if the service returned a value for the UserAndGroupQuotas property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • userAndGroupQuotas

        public final List<OpenZFSUserOrGroupQuota> userAndGroupQuotas()

        An object specifying how much storage users or groups can use on the volume.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasUserAndGroupQuotas() method.

        Returns:
        An object specifying how much storage users or groups can use on the volume.

      • copyTagsToSnapshots

        public final Boolean copyTagsToSnapshots()

        A Boolean value indicating whether tags for the volume should be copied to snapshots of the volume. This value defaults to false. If it's set to true, all tags for the volume are copied to snapshots where the user doesn't specify tags. If this value is true and you specify one or more tags, only the specified tags are copied to snapshots. If you specify one or more tags when creating the snapshot, no tags are copied from the volume, regardless of this value.

        Returns:
        A Boolean value indicating whether tags for the volume should be copied to snapshots of the volume. This value defaults to false. If it's set to true, all tags for the volume are copied to snapshots where the user doesn't specify tags. If this value is true and you specify one or more tags, only the specified tags are copied to snapshots. If you specify one or more tags when creating the snapshot, no tags are copied from the volume, regardless of this value.

      • readOnly

        public final Boolean readOnly()

        A Boolean value indicating whether the volume is read-only. Setting this value to true can be useful after you have completed changes to a volume and no longer want changes to occur.

        Returns:
        A Boolean value indicating whether the volume is read-only. Setting this value to true can be useful after you have completed changes to a volume and no longer want changes to occur.

      • equals

        public final boolean equals​(Object obj)
        Overrides:

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object

      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
