recordSizeKib

Specifies the suggested block size for a volume in a ZFS dataset, in kibibytes (KiB). For file systems using the Intelligent-Tiering storage class, valid values are 128, 256, 512, 1024, 2048, or 4096 KiB, with a default of 1024 KiB. For all other file systems, valid values are 4, 8, 16, 32, 64, 128, 256, 512, or 1024 KiB, with a default of 128 KiB. We recommend using the default setting for the majority of use cases. Generally, workloads that write in fixed small or large record sizes may benefit from setting a custom record size, like database workloads (small record size) or media streaming workloads (large record size). For additional guidance on when to set a custom record size, see ZFS Record size in the Amazon FSx for OpenZFS User Guide.
