Avoid performing overlapping page updates from concurrent writers. If you have a sharded database, it would be a good idea to assign a writer to a shard and update shards through the assigned writer. The mapping is only logical in the application layer. Physically, the data in the storage volume is visible to all writer nodes. Transactions that span shards can still be executed from a single writer. When a conflict is raised by the database node to the application layer, retry the transaction. Techniques such as exponential backoff give the buffer pool time to catch up with replication and reflect the most recent change to the page touched by the transaction, increasing the chances of success. Based on your own application’s design and needs, route queries to writers in a way that achieves an acceptable write conflict ratio, equal writer utilization, and the best possible availability. By default, Aurora uses a read-after-write consistency, where reading data is consistent if done on the same node on where the writer wrote their information. Synchronizing this write may take several milliseconds to reach consistency on other nodes. Additionally, multi-master clusters provide another option at session level called global read-after-write (GRAW). With GRAW it is possible to see instead only consistent data, no matter which node updated this. Implementing these measures does come with a performance penalty, and thus Amazon advises to only apply this for specific queries that need this behavior. In a recent announcement, Amazon has publicized the general availability of Aurora Multi-Master, which allows for reading and writing on multiple MySQL database instances across several Availability Zones (AZs). This brings high availability capabilities, as the platform no longer needs to trigger a fail-over or promote a read-replace upon failure of database instances.Amazon Aurora is a relational database that is compatible with open-source databases MySQL and PostgreSQL. It is backed by multiple compute nodes and a multi-AZ storage layer, and is fully managed by Amazon Relational Database Service (RDS). Correspondingly, the service is similar to those of other large cloud providers like Microsoft’s Azure Database Services and Google’s Cloud SQL. Regarding the new multi-master feature, it is essential to note that this is currently only available on the MySQL compatible edition, limited to specific regions, and supports a maximum of two writer nodes.Previously, when just single-master mode was available, a failure of an Aurora database instance resulted in a fail-over to another instance. Downtime on write operations accompanied this fail-over, which, depending on the database, could run up to thirty seconds in the case of a CNAME record adjustment, or even sixty seconds in the case of the platform needing to restart the database. However, with the introduction of Multi-Master, Amazon has now presented a means to eliminate the need for a fail-over. Instead, applications can redirect their read and write actions to the other instance, which is already up and running, and was previously processing other database operations as well. Preferably a dedicated connection manager should coordinates this, for example, by implementing a singleton which keeps track of connections, database health, and makes a logical distribution of database calls. Source: https://aws.amazon.com/blogs/database/building-highly-available-mysql-applications-using-amazon-aurora-mmsr/When using Aurora Multi-Master, each node in the cluster is both a reader and a writer, and thus applications can use all nodes to handle their workloads. This provides high availability for the databases, although this also may introduce issues surrounding replication and consistency. The platform takes care of handling this by using a quorum of storage nodes that either approves or rejects any changes which the master nodes present to them. For optimal performance the connection manager should avoid conflicts on writes as much as possible by distributing connections to hit the same pages as little as possible. On this subject Mukund Sundararajan, solutions architect at Amazon Web Services, provides several best practices to use when designing applications.

In the Columbia River Gorge, schools in the Stevenson-Carson School District have been closed.
Darryl Koistinen, who owns Dobler Hill Dairy in Woodland, milks one of nine goats during the evening milking Wednesday. Koistinen and his wife, Andria, produce and sell raw goat milk at their farm and local produce stands. To some, raw milk has an unwarranted bad rap. Raw milk dairies in Washington are closely regulated and monitored to detect and prevent contamination.To others, the unpasteurized milk isn’t scrutinized enough. Raw milk can contain harmful bacteria — such as E. coli, salmonella and listeria — which are responsible for serious illnesses.Darryl and Andria Koistinen, owners of the Dobler Hill Dairy in Woodland, agree some criticism is warranted. They produce and sell raw goat milk on their 10-acre farm. Their product can be risky, especially for pregnant women, children and people with lower resistance to disease.“We like our customers to know there’s a risk when they buy it,” Andria said.But they also believe raw milk illness outbreaks, like the recent event stemming from a farm near Wilsonville, Ore., cast the whole industry in a bad light.“It’s not something for everybody,” Darryl said. “Pasteurization is good for the general public. … For the people that want to drink (raw milk), they should.”

Camron Rowen, 12, a student in Mike Holland’s math class at La Center Middle School, starts work on math problems on his iPad. The La Center School District expanded its iPad program this year. LA CENTER — As Mike Holland paced the front of his seventh-grade math class at La Center Middle School, his students settled into their seats, touch screens in hand.There was no click-a-tat of three-ring binders opening or the rustling of glossy textbook pages turning. There was just the silent unsheathing of tablet computers from their cloth vessels and the chatter of excited voices.This is the new classroom.As touch-screen gizmos become ubiquitous tools for everyday life, they’re also becoming mainstays of Clark County classrooms. Districts as far afield as La Center, Battle Ground, Vancouver and Washougal use, or have used, iPads at one time or another. This school year, school districts are expanding their iPad programs. In La Center, the program started as a pilot program in 2012.Holland, 63, is in his first week of incorporating the tablets into his daily lessons, and he’s enthusiastic about what he’s seen. He supplements the traditional math curriculum with interactive lesson plans from a website called Khan Academy that was recently featured on CBS’ “60 Minutes.”Khan Academy provides interactive tutorials, while Holland provides the hands-on teaching, which involves roaming the room and answering questions. What this means is a more fragmented form of learning, he said, but one that’s based on doing rather than listening to teacher lectures.
Washington’s Bishop Sankey (25) celebrates his touchdown against Illinois with Dexter Charles during the first half Saturday at Soldier Field in Chicago. Sankey rushed 35 times for 208 yards in the Huskies 34-24 win. CHICAGO — Keith Price threw for 342 yards and two touchdowns, Bishop Sankey ran for a career-high 208 yards and No. 19 Washington got a rare road win, beating Illinois 34-24 at Soldier Field on Saturday.Josh Shirley added four sacks, and the Huskies came out on top after dropping seven of nine away from home. They hadn’t won on the road outside the Pac-12 since beating Syracuse in 2007.Washington (2-0) had a tougher time in this one after keeping high-powered Boise State without a touchdown and racking up 592 yards in a 38-6 win two weeks ago. The Huskies built a 21-point lead in the third quarter and hung on after it dwindled to seven in the fourth, sending Illinois (2-1) to its sixth straight loss against ranked opponents.The Illini cut it to 31-24 on Aaron Bailey’s 10-yard run with 9:10 remaining, but Washington’s Travis Coons kicked a 32-yard field goal to make it a 10-point game with 4:44 left. Gregory Ducre then picked off a deep pass by Nathan Scheelhaase, sealing the win for the Huskies.Price completed 28 of 35 passes. Kevin Smith caught five passes for 104 yards, and Sankey came up big again after running for 161 yards in the opener. He scored a 31-yard touchdown on a screen in the first half and on a 1-yard run early in the third quarter.
People in Ohio, Michigan and 15 other states found themselves unable to use their food stamp debit-style cards on Saturday, after a routine test of backup systems by vendor Xerox Corp. resulted in a system failure.“While the electronic benefits system is now up and running, beneficiaries in the 17 affected states continue to experience connectivity issues to access their benefits. Technical staff is addressing the issue and expect the system to be restored soon,” Xerox spokeswoman Jennifer Wasmer said in an emailed statement. “Beneficiaries requiring access to their benefits can work with their local retailers who can activate an emergency voucher system where available. We appreciate our clients’ patience while we work through this outage as quickly as possible.”U.S. Department of Agriculture spokeswoman Courtney Rowe underscored that the outage is not related to the government shutdown.Shoppers left carts of groceries behind at a packed Market Basket grocery store in Biddeford, Maine, because they couldn’t get their benefits, said fellow shopper Barbara Colman, of Saco, Maine. The manager put up a sign saying the EBT system was not in use. Colman, who receives the benefits, called an 800 telephone line for the program and it said the system was down due to maintenance, she said.“That’s a problem. There are a lot of families who are not going to be able to feed children because the system is being maintenanced,” Colman said. She planned to reach out to local officials. “You don’t want children going hungry tonight because of stupidity,” she said.Colman said the store manager promised her that he would honor the day’s store flyer discounts next week.Ohio’s cash and food assistance card payment systems went down at 11 a.m., said Benjamin Johnson, a spokesman for the Ohio Department of Job and Family Services. Ohio’s cash system has been fixed, but he said that its electronic benefits transfer card system is still down. Johnson said Xerox is notifying retailers to revert to the manual system, meaning customers can spend up to $50 until the system is back online. Recipients of the state’s supplemental nutrition assistance program, or SNAP, should call the 800 number on the back of their card, and Xerox will guide them through the purchase process.
Lifeguard Carter Coval got an award Tuesday night for rescuing a 5-year-old boy from drowning at a Hazel Dell pool in December.Fire District 6 Chief Jerry Green lauded Coval, 17, for being calm in a stressful situation and using his water rescue skills. During the district’s fire commissioner meeting at the Hazel Dell fire station, Green recalled what happened that Friday night, Dec. 27, when firefighters were called to Lakeshore Athletic Club for a near-drowning.Coval had seen a boy floating facedown in the pool. He asked another swimmer to nudge the boy, and when the boy didn’t respond, Coval jumped in to pull him out of the water. The boy was unconscious, had blue lips and was foaming at the mouth and nose.While another lifeguard called 911, Coval found that the boy didn’t have a pulse and wasn’t breathing. Coval performed CPR and then performed rescue breathing after he noticed the boy had regained his pulse. When the boy started to cough up fluids, Coval put him in a recovery position on his side. The boy, named Luke, regained consciousness about a minute before paramedics arrived.Luke recovered well and wanted to go swimming again that weekend. His parents said Tuesday that they will invest in swimming lessons for the boy.Coval’s parents and Luke’s family clapped as Coval accepted the award.Coval has been working as a lifeguard at the athletic club for about a year. He said the experience made him realize how temporary life can be.
For The Columbian’s editorial board interview with county prosecutor candidates Josephine Townsend and Tony Golik, click on the right edge of the photo above.In her bid to oust Tony Golik as Clark County prosecutor, private lawyer Josephine Townsend, 54, of Vancouver has criticized the incumbent for alleged mismanagement of his office. Yet public documents show the Republican challenger has a record of missteps, discipline and mismanagement during her career.After three years as Vancouver’s city prosecutor, her performance led to her resignation in lieu of termination in February 2005. She was disciplined by the Washington State Bar Association in January 2006 for misconduct during her term as city prosecutor, and then failed to disclose the discipline when she was appointed to the state Commission on Judicial Conduct in March 2006. She stepped down from the commission in July 2007 when members of the commission’s executive committee learned about the discipline from another source and asked for her resignation.Meanwhile, when she sought judicial offices, Townsend has garnered mainly negative feedback in Clark County Bar Association peer opinion polls on categories such as integrity.Resignation in lieu of terminationPublic records suggest that Townsend resigned to avoid being fired from her job as Vancouver’s city prosecutor in February 2005 following a human resources investigation into allegations that she violated court rules, lied to cover up her mistakes, and was a retaliatory and controlling manager.
How to donate in Bud Van Cleve’s nameIn lieu of flowers the family has asked that donations be made in memory of Van Cleve to the Hazel Dell Youth Party (checks made out to Three Creeks Community Partners; visit www.threecreekscommunitypartners.org) or to Boys & Girls Clubs of Vancouver (checks to the Clinton and Gloria John Boys & Girls Club, 409 N.E. Anderson Road Vancouver, 98665).During a celebration honoring the life of Bud Van Cleve on Saturday, one of his daughters said Van Cleve would be greeted in heaven by friends and family members who loved him. And if Van Cleve’s life served as any insight into his afterlife, those friends and family will likely be greeted by a man with unfailing energy and a few ideas on how to improve the place.Van Cleve, whose moniker was the “Mayor of Hazel Dell,” died on Nov. 5 at age 84. On Saturday afternoon, at the Vancouver First Church of God, friends and family remembered a loving father and husband, a caring grandfather and a man who was involved in more than 60 local boards, committees, councils and organizations. Doug Ballou, who worked with Van Cleve in the Northeast Hazel Dell Neighborhood Association, told a story of a time Van Cleve took a piece of asphalt to the county commissioners to illustrate the need for some local road improvements.

The Cotai properties affected include those operated by Sands China, Galaxy Entertainment Group and Melco Resorts but there are also reports that some IRs on the Macau peninsula have also been affected. Notably, the crackdown has been limited to those shops operating inside large resorts – pawnshops and jewelry stores located on the streets still have their POS terminals and are still offering Union Pay services.Analysts described the crackdown as unusual given the lack of information provided by authorities.“When ATMs were ordered to undergo KYC enhancement, the process was well explained and orderly implemented with no real impact to using such devices,” said Bernstein’s Vitaly Umansky, Zhen Gong, Cathy Huang and Kelsey Zhu.“Consequently, the move is likely broader and trying to make it more difficult for customers to utilize Union Pay in this manner directly in casinos. The shops operating at casino premises have largely been doing so not within the spirit of the law in Macau which does not want such transactions occurring within the casinos.”In a note seen by IAG, JP Morgan’s DS Kim said most shops “do not seem to have a clear understanding of why or when they’ll get their Union Pay terminals back.”However, Morgan Stanley’s Praveen Choudhary and Jeremy An referred to a statement by China’s central bank promising to work closely with law enforcement agencies to crack down on irregularities in internet finance, underground banks and illegal foreign exchange trading, adding that Chinese banks were simply upgrading their POS terminals at Macau pawn shops.Pointing to this statement, Bernstein commented, “The coordinated effort is focused on reducing shady financial transactions that occur with no government oversight or transparency. The recent actions in Macau may be part of the broader China government strategy.“If the government broadens the effort to reduce outflows through Macau by further limiting Union Pay capabilities and/or going after underground banking channels, the headwind to Macau GGR would be more negatively impacted than currently contemplated.” RelatedPosts JW Marriott at Galaxy Macau named venue and Galaxy Entertainment Group named Venue Sponsor for 2019 Asian Gaming Power 50 Black Tie Gala Dinner Load More Galaxy offers first glimpse of new Galaxy Macau convention center ahead of 2021 launch Melco International Development grants Evan Winkler HK$269 million share options Macau authorities have embarked on a new crackdown on the use of Union Pay cards, removing Union Pay POS terminals from pawnshops inside a number of Cotai integrated resorts.According to reports, the crackdown has been implemented by the government in conjunction with ICBC (Macau) and the Bank of China (Macau) although it is not yet known whether the removal is permanent or simply part of an exercise to replace older terminals with updated versions offering enhanced KYC technology.
Japanese lawmakers may consider taxing the casino winnings of some foreign visitors, including those from China, as Diet discussions continue on the IR Implementation Bill.According to a report in the The Asahi Shimbun, tourists who gamble in Japanese casinos may be subject to the tax treaty that their home nation has signed with Japan. Of the 123 states and regions it currently has tax treaties with, Japan can charge income tax on casino winnings to visitors from China, India and Singapore among others. Those from countries with no Japan tax treaty are also liable to pay income tax on casino winnings.
