“Small” CPUs such as those found in embedded SoCs have lacked this feature since their inception. I trace this convention back to the introduction of the ARM7TDMI core in the 1990s. Back then, transistors were scarce, memory even more so, and so virtual memory was not a great product/market fit for devices with just a couple kilobytes of RAM, not even enough to hold a page table. The ARM7TDMI core’s efficiency and low cost made it a run-away success, shipping over a billion units and establishing ARM as the dominant player in the embedded SoC space.

In most cases skip indices should only be considered once other alternatives have been exhausted - specifically this advanced functionality should only be used after investigating other alternatives such as modifying the primary key, using projections, or materialized views. In general, only consider skip-indices if there is a strong correlation between the primary key and the targeted, non-primary column/expression. In the absence of any real correlation, the skipping index will match for most blocks - resulting in all granules being read into memory and evaluated. In this case, the index cost has been incurred for no benefit, effectively slowing the full table scan.
Fresh off launching the low-cost MacBook Neo, Apple is reportedly preparing at least three new products that will fit into its highest-end "ultra" lineup. According to Bloomberg's Mark Gruman, the next batch of releases may not bear the "ultra" name, like its Watch, but will all command price premiums over their mainline counterparts.

Other US moves to dampen oil price increases include allowing India to access Russian oil currently held in floating storage in the region. Washington has also floated tapping its strategic petroleum reserve or even intervening in futures markets — officials have since downplayed these ideas, while Trump has brushed off inflationary worries even as US gasoline prices spike.
