The diagram above illustrates the method used by Redshift which is based on sorting data during load to maximize read performance, in this case by TEAM and then CITY.Īs data is loaded it’s sorted by a SORT KEY, and the minimum and maximum value recorded for each 1Mb block. Instead, the data is physically stored to maximize query performance using SORT KEYS. On Redshift, there’s no need to devise an indexing strategy or drop and rebuild indexes around batch ETL loads, as Redshift does not support traditional indexes. Even the Bitmap Index, specifically designed for analytic query performance leads to significant concurrency issues when maintained by multiple writers, and is often disabled prior to bulk load operations. While a B-Tree supports rapid access for both direct lookup and scan operations, it’s a major cause of locking contention issues when bulk loading data, which can lead to performance issues. Sort Keys and IndexesĮver since Bayer and McCreight first proposed the B-Tree index in 1972 it has been the primary indexing method used by almost every database, although database designers must carefully balance a trade-off of better read performance and write throughput. Of course, the extent to which the query slice can run independently in parallel depends upon the extent to which the workload can be balanced, and the remainder of this article explains how this can be achieved using Sort Keys and Distribution Keys. This means any given query can be executed in parallel across multiple cores reading multiple disks, thus maximizing throughput. When a query is executed, the leader node breaks up the task into a number of parallel steps, executed by the Compute Nodes which actually store the data, and perform the heavy lifting. This method maximizes parallel execution and supports scalability as the system can be migrated to a larger cluster with additional nodes. When data is loaded, it’s distributed across each compute node in the cluster as a series of slices, where each slice corresponds to a CPU core, memory allocation, and disk space. The diagram below illustrates how every query is submitted to the Leader Node which is responsible for parsing the query, determining the best execution plan, and coordinating and aggregating results. System Architectureīefore diving into the detail it’s worth giving an overview of how Redshift is internally architected. While there are few options available to tune or customize the database, it’s absolutely critical to correctly design the physical table layout to maximize performance. ![]() Amazon Redshift is (for the most part) a Data Warehouse as a service, and there’s no need to provision hardware, install databases or patches with few options to tune the system. ![]() ![]() ![]() Even if you swap to straight blasting at this point, it's a race where you're out of your tricks and the other guy hasn't even brought his subclass abilities to bear yet. You're now in the action economy crunch - you have more things you have to do to maintain effectiveness than the other guy. At the end of that, you're not hidden, completely empty on sorcery points, and down more slots than the other guy. And, if you dominate the wizard, cool but it's likely to get advantage on a proficient saving throw against your poor DC (again, DC 15).Įven if you game out a situation where you get your perfect setup and things largely go your way, this isn't overwhelming at all - you burn a huge amount of resources for about 20 damage. If you want to switch to a neat enchantment spell against the wizard, perhaps a suggestion or a charm or a dominate (which is your other 5th level slot), you certainly can, but the wizard is immediately free of telekinesis when you drop concentration, which means you've largely wasted a 5th level slot to begin with. It's a neat trick, but it's unsustainable and so really only useful in limited cases. The wizard now has an edge in available slots - they've spent less than you have, especially since you now will be bonus action converting more slots into sorcery points. Regardless, the wizard can see you now and can cast whatever they want (restrained doesn't prevent spellcasting) and counter your counters because you don't have the sorcery points to make them subtle as often. And the wizard can counter that casting unless you're converting and then casting psionically, which is a great way to burn your points and be stuck in the same loop. You'll have to cast normally next round to use your bonus action to convert a slot for points. You're going to have to start upcasting counterspells and it's likely that the wizard won't be restrained next round as you can't magical guidance yourself. You've done 4.5d8 damage to the wizard, which hasn't brought him below half. The wizard is down three countered spell slots, and you're tapped on sorcery points, down 3 3rd level slots and 1 5th. Now, when the wizard casts and you counterspell, you cannot use subtle, so you reveal yourself in casting. You're now tapped on sorcery points, having spent another 2 on that quickened mind thrust. They choose to keep an action for next turn. This mind thrust succeeds! The wizard fails their check, but they're okay because they still have hitpoints left. Next turn, you try mostly the same thing - concentrate on telekinesis and throw a spell. The mage goes, and casts a spell, which you subtly counter, for another 3rd level slot and a sorcery point. Still, it's half of 3d8, so marks on the board! You're now down 7 sorcery points. You've done some damage, finally! Unfortunately, it's likely the wizard has saved, as INT is his prime stat and he's proficient, so against your DC 15 he has +8 or +9 to save. You can do this because you just maintained Telekinesis instead of casting it. That's 2 sorcery points for Mind Thrust and 2 for quickened spell. You then cast a quickened psionic spell, let's say Mind Thrust, at 2nd level. Another 66% chance, which means you're likely to have used magical guidance at this point because you have about a 50/50 chance of having failed (slightly better). ![]() So, next turn, you maintain concentration on telekinesis and reup the restraint as an action. So, first round done, you're down a 5th slot and a 3rd slot, 2 sorcery points for subtle, and perhaps another for a use of magic guidance. If it is higher than 3rd, your +3 CHA will hurt a bit as you'll need an 11 minimum on the die (for a 4th level spell), which is only a 50% chance. Provided the spell isn't a higher level than 3rd, you succeed. The enemy may not try to cast a spell, which you can subtly counterspell with a 3rd level slot. You've cast a 5th level spell, so that's out. You're now done, because you can't case a quickened psionic spell because using a bonus action to cast limits you to only casting a cantrip otherwise. Let's say you do it, though, and the target is restrained. That's still only a 66% chance of success. So, you do, but you have a +3 to CHA and let's say the other guy has a -1 to STR, giving you a 4 point difference. This is because you cannot both use subtle and distant at the same time. Let's assume you've hidden - you cast a 5th level spell subtly and use telekinesis at a range of 60 feet. ![]() ![]() ![]() Newer-generation Trex deck boards (Trex Transcend®, Trex Enhance®, Trex Select®, Trex Contour®) are manufactured with a high-performance shell that wraps around three sides of the composite board to protect it from the elements, providing resistance to fading, staining, scratching and mold.

Granted, anyone with a decent grasp on software can figure out what’s what, but, like it or not, startup tutorials have become standard for password managers. KeePass dumps you into the interface with little indication about where to go. You can launch KeePass right after installation finishes, but the hand-holding ends there. You can breeze through the installation by clicking “next” - that’s what we did - but it would’ve been nice to see a tooltip or something similar for the vaguely named components. There’s an 8MB component simply called “optimize KeePass performance.” The core files only account for 3.7MB of the 14.9MB installation.

The look is dated, there’s no arguing that, but thankfully the website isn’t too difficult to get around. If you’ve ever downloaded open source software, KeePass’ website should be immediately familiar. Portable applications can run without any additional installation, meaning you can store KeePass on, say, a USB stick and load it up anywhere. With it, you can take your databases anywhere you go. If you want to build your own installer, you can download the KeePass source code, too.Īlthough we love the platform support, the most interesting tool is KeePass Portable.

The orifice of the u-tube viscometer produces a fixed resistance to flow. Kinematic viscosity is measured by timing how long it takes oil to pass through the orifice of a capillary when only subjected to the force of gravity see Figure 2. Kinematic Viscosity describes the resistance of a liquid to flow under the influence of gravity. HTHS viscosity is measured at 150☌, to simulate realistic oil shearing conditions in an engine using a tapered bearing simulator viscometer. HTHS dynamic viscosity is designed to ensure engine lubricants maintain sufficient film strength to prevent excessive wear under engine operating conditions, whilst maintaining a viscosity low enough to improve fuel efficiency and emissions. HTHS dynamic viscosity is the industry standard that best replicates engine oil behaviour. HTHS viscosity is a measure of lubricant flow resistance under dynamic conditions. CCS viscosity is one of the factors used to define the “ W” or “winter” part of a multigrade oil. The cold-cranking simulator is a requirement which is used to define the viscosity grade of the oil. The procedure simulates the viscosity of oil in crankshaft bearings when starting the engine at low-temperatures. Figure 1 – Viscosity index comparisonĬold Cranking (viscosity) Simulator (CCS)Ī cold cranking (viscosity) simulator or CCS, is a device used to determine the low temperature performance of lubricants, when starting a cold engine i.e., during the cold-cranking phase. The aim is to keep the viscosity as stable as possible and keep the line (see fig.1), as flat as possible. Most modern hydrocraked oils have a very high viscosity index, meaning that a fully-synthetic oil no longer has this advantage over HC oils. Traditionally, synthetic oils were out on their own in terms of viscosity stability, but nowadays a high-quality hydrocracked oil can easily compete with synthetics. As a rule, the higher the viscosity index, the lower the change in viscosity with increasing temperature i.e., the oil viscosity behaves in a more stable manner for longer. The viscosity index describes the change in viscosity with temperature and is calculated from the kinematic viscosity at 40☌ and 100☌. Engine manufacturers specify oils that behave consistently to ensure consistent lubrication performance, permitting only minimal wear under normal operating conditions. Quality oils that have a high viscosity index (VI) remain stable with minimal variation in viscosity over the entire temperature range. Automotive lubricants are required to work at cold ambient temperatures i.e., down to -40☌ and up to 200☌. Many lubricant applications, for example engine oil, require the lubricant to perform near uniformly across a wide range of operating conditions. The viscosity index is a crucial metric, which can be used to assess the viscosity stability of an oil. ![]() Modern automotive engine oils are almost exclusively multigrade oils. The 5W part refers to the low-temperature viscosity or how the oil behaves in winter, 30 refers to the high-temperature viscosity (summer). Multigrade oils must fulfil two viscosity specifications, their viscosity grade consists of two numbers such as 5W-30, for example. Under the ISO VG system, oils are generally separated into two main groups, multigrade oils and monograde oils. The resulting system is known as the International Standards Organization Viscosity Grade, ISO VG. A group of renowned standardisation institutes consisting of the International Standards Organization (ISO), American Society for Testing and Materials (ASTM), Society for Tribologists and Lubrication Engineers (STLE), British Standards Institute (BSI) and Deutsches Institute for Normung (DIN) created a common viscosity classification. In 1975 a common system of grading engine oils according to their viscosity was agreed. Low viscosity = fluid = fast flowing = less stable film High viscosity = viscous = slow flowing = more stable film In order to achieve a good flow of oil around the engine and good flow properties at low temperatures, the oil must be low-viscosity. The faster the oil flows around the engine, the better, i.e., the faster it can provide protection and prevent wear. The time it takes for an oil to travel around an engine, especially at low temperatures, depends on the oil’s viscosity. How does viscosity affect engine oil selection? ![]() The technical definition of viscosity is the measure of a fluid’s internal flow resistance. Put simply, viscosity indicates how thick a fluid is and how easily it flows. ![]() ![]() ![]() OR you can go for a jog and leave Pokemon GO running. Why not go for 1 hour?
