The extent allocation comes in as the GAM tracks when SQL Server needs to allocate a uniform extent.An extent in SQL Server is comprised of 8 x 8KB pages, 64KB, and this is usually the unit of data allocation so if you have a table that’s larger than eight pages, any time we allocate space to that table we will create a full extent, and this is a uniform extent because all eight pages in that extent belong to that object.So, any time SQL needs to allocate a uniform extent to an object SQL will go to the GAM page and check the availability. The GAM is a bitmap, so if the bit is 1 then that extent is available to be allocated, and if it is 0 then it is not available to be allocated. Once SQL Server has allocated the extent, it just flips the bit for that GAM page from 1 to 0 to show that it is no longer available.The larger the file, the more GAM Pages you will have, for the GAM you will get another GAM page after 63,904 extents.Page 3 is for the shared global allocation map (SGAM) and this page is used if SQL needs to allocate space on a mixed extent. This SGAM page tracks mixed extent usage for when an extent is being used by more than one object. So, if I have an object that is less than eight pages and I don’t want to allocate a full extent, we will use a mixed extent. By default, when a brand-new object is created the first eight pages will be allocated on a mixed extent.The SGAM is a bitmap, so if the bit is 1 then it’s being used as a mixed extent and has space available to be allocated, then we would look for the corresponding PFS page to find the empty pages within that extent, and then we would allocate that page. The important point here is the SGAM is used in conjunction with the PFS page in order to allocate space on a mixed extent and again after about 64,000 extents you get another SGAM on the same file.When you have multiple files in tempdb, you get another immediate header, PFS, GAM, and SGAM because all files will have the same structure and with multiple files we try and share the workload over these files.SQL Server spreads out object allocations across files in the same filegroup based on the proportional fill algorithm. We try to keep the same percentage of free space in each file within the file group so if all the files in the file group start at the same size and they stay the

Seon-gam Island, South Korea – Two men stand at the entrance to a forest surrounded by tall pine trees on an island south of the capital Seoul.In the middle of the forest there is a large clearing and an excavation site.The words written on a safety notice reveal what this forest hides: “Seon-gam Academy Graveyard Recovery Operation”.Chun Jong-soo and Pak Sung-ki were just boys when they were among thousands cleared off the streets by South Korean authorities for alleged vagrancy, and held for years as inmates at institutions like Seon-gam Academy.Seon-gam island was only accessible by boat when Chun and Pak were first detained in 1965 and 1980, respectively.Fighting to control his trembling voice, Chun says he remembers the burial site now being excavated here. He was among the young detainees forced to bury the bodies of his fellow inmates who died trying to escape. Chun told Al Jazeera how they would recover bodies that washed up on the island’s shores and bury them at this forest cemetery.“It was meant to show us the consequences of trying to escape,” Chun said.“Memories of seeing those bodies still haunt me in my sleep.”A photo of an image showing young inmates arriving by boat on Seon-gam Island [David D. Lee/Al Jazeera]Hundreds and possibly thousands died amid the forced labour, violence and sexual abuse that prevailed in the group homes and detention centres – like the Seon-gam Academy – that were established across South Korea during the country’s decades of heavy-handed rule from the 1960s through to the 1980s.Among the most notorious was “Brothers Home”, a so-called welfare centre that was once located in the southern port city of Busan, where thousands were enslaved and abused in a state-sponsored programme to punish vagrants and clear the homeless from South Korea’s streets.While police did most of the seizures, Brothers Home employees were also allowed to patrol the city in trucks to do the kidnapping themselves. Children, people with disabilities, and the homeless were rounded up, detained and forced to work at the home where survivors recounted witnessing people beaten to death by staff or left to die from injuries.‘Real hell’ v TV dramaThe existence of these brutal institutions in South Korea has come to wider attention as Netflix’s Squid Game gains global attention.Season two of the South Korean drama kicked off late last year by racking up the largest audience ever for the debut of

(ColumnStore indexes, temporal tables, In Memory OLTP, etc.) all these new features require new metadata to be tracked, therefore the number of system tables we need to delete from is increasing, which makes the process more impactful.Temp table cache contention can be more prominent on larger SQL Server environments, larger core counts and as the size of the cache and the number of concurrent threads accessing the cache grows, this can introduce slower cache access as well as contention for the memory object associated with the cache.This condition can manifest in two different ways: CMEMTHREAD waits and SOS_CACHESTORE spinlock waits. To address temp table cache contention, it is recommended to track these wait conditions for evidence and ensure you have installed the latest cumulative updates (CUs) for SQL Server.Check out our Tech Community blog for more information on temp table caching in SQL Server.SQL Server 2022 tempdb improvementsIn SQL Server 2022 we have addressed the final common areas of contention by introducing concurrent GAM and SGAM updates similar to the Concurrent PFS updates.We use the Global Allocation Map (GAM) pages when we are looking for uniform extents and the Shared Global Allocation Map (SGAM) pages when we are looking for mixed extents in tempdb.In previous releases, under higher concurrent workloads we may have GAM contention where many different threads attempt to allocate extents on the same GAM page and each thread must first wait for another thread to release their UPDATE latch before they can obtain their own latch to allow them to make changes—so, we are just waiting in line.As can be seen in the workload example below, on SQL Server 2019 there is a wall of GAM contention driving over 123,000 counts of contention with the longest wait taking 949 milliseconds.The reason for this is that with the update latch, only one thread can modify the GAM page at a time, leading to contention. This is the primary reason we still need multiple data files and because of this contention, SQL Server throughput is decreased and workloads that require many updates to the GAM page will take longer to complete while the machine’s CPU will be underutilized. This contention is due to the workload volume and especially the use of repetitive create-and-drop operations.Starting with SQL Server 2016, we changed the default behavior to always allocate uniform extents when creating new objects in tempdb. This helped avoid most of the SGAM contention, but we still use mixed extents for Index Allocation Map (IAM) page allocations. IAM pages are used to track all the pages that belong to an object, so every object that gets created has at least one IAM page. For most workloads, these IAM page allocations don’t

He said.Before his time at Seon-gam Academy, Pak lived in a middle-class family. Their home had the only television set in his neighbourhood at the time.But his life took a drastic turn when he was picked up at random by government officials while he walked around downtown Seoul as a 15-year-old.A photo of an original image of child inmates sitting in front of government officials at Seon-gam Academy in the 1960s [David D. Lee/Al Jazeera]Released from Seon-gam after a year and a half when it was shut down in 1982, Pak was never able to return home. His family, like the families of other inmates, did not know what had happened to him. They filed missing person reports at the police station but he was not found.When Pak was eventually released from Seon-gam, he went to his old house but no one was home as his family had moved. It was only when Pak’s family revisited the police one last time to see if they had any news of their lost son – before they moved to the US – that they heard he was in prison.Pak was reunited with his family for the first time in years, but prison walls now separated them.“After I came out [of Seon-gam], I couldn’t work anywhere as I didn’t have any skills. I didn’t have anywhere to go,” Pak said.“So, I lived on the streets and worked as a paperboy and a scrap man just to make enough to buy food. One day, I got caught trying to steal a plate of food from someone. That became my first time entering prison,” he said.Pak’s family moved to the US shortly after he was reunited with them. He could not follow due to his criminal record and they never were able to fully reconnect as a family. They would live separate lives and only communicate through international phone calls.Pak told how he spent time in and out of prison until he was 45 years old.“I’ve frequently visited the psychiatric hospital,” the now 59-year-old told Al Jazeera, revealing he had tried twice to take his own life.“I’ve only recently found happiness,” he added, telling how he had taken up painting in an effort to “give hope to others”.Several of Chun and Pak’s fellow inmates from the academy have not been so lucky – they have simply gone missing and some have also taken their own.

Lives.A group of Seon-gam Academy survivors who have formed a committee to bring attention to what happened to them while detained on the island [David D. Lee/Al Jazeera]‘I have a dream now’The remains of Seon-gam Academy’s welfare centre and its associated buildings are still intact on the island.It is one of the few – if not only – welfare centres from that period in South Korea’s history that plans to restore what is left of its dark past and turn it into a site of commemoration for victims and survivors.Gyeonggi provincial authorities are on board to assist the survivors’ committee in their push for more work to be undertaken on the cemetery excavation site. Work is also under way to transfer what is now a temporary Seon-gam museum to a permanent location, and to restore buildings that once served as what Chun and Pak frequently refer to as a “version of hell”.In one corner of the museum are Pak’s paintings of his time at the academy. Painting now serves as a form of mental and emotional therapy, he said, recounting how he learned to draw through YouTube videos and it had opened a new chapter in his life.“I have a dream now. It’s to draw paintings for kids at youth shelters,” he said, explaining how young people in orphanages and other institutions remind him of himself and how he wants to show them to develop their own artistic skills.Pak Sung-ki in front of his drawings on display at a temporary Seon-gam Academy history museum [David D. Lee/Al Jazeera]For Chun, it has only been four years since he first opened up about his experience at the academy to those closest to him.Now he wants that openness reciprocated.If it was South Korea’s regimes of the past that led Chun, Pak and thousands of other young people to be detained against their will, the brief declaration of martial law in December by South Korea’s current and impeached President Yoon Suk-yeol has brought further misfortune for Soen-gam’s survivors.The political turmoil caused by Yoon forced the cancellation of a planned meeting between the island’s survivors, the country’s minister of the interior and safety and the governor of Gyeonggi Province.“We’re angry and frustrated,” said Chun, who serves as the vice president of the Seon-gam Academy survivors committee.“They were supposed to come here and offer a formal apology in front of the survivors,” he said.“Now, we are

The GAM is a bitmap, so if the bit is 1 then that extent is available to be allocated, and if it is 0 then it is not available to be allocated. Once SQL Server has allocated the extent, it just flips the bit for that GAM page from 1 to 0 to show that it is no longer available.The larger the file, the more GAM Pages you will have, for the GAM you will get another GAM page after 63,904 extents.Page 3 is for the shared global allocation map (SGAM) and this page is used if SQL needs to allocate space on a mixed extent. This SGAM page tracks mixed extent usage for when an extent is being used by more than one object. So, if I have an object that is less than eight pages and I don’t want to allocate a full extent, we will use a mixed extent. By default, when a brand-new object is created the first eight pages will be allocated on a mixed extent.The SGAM is a bitmap, so if the bit is 1 then it’s being used as a mixed extent and has space available to be allocated, then we would look for the corresponding PFS page to find the empty pages within that extent, and then we would allocate that page. The important point here is the SGAM is used in conjunction with the PFS page in order to allocate space on a mixed extent and again after about 64,000 extents you get another SGAM on the same file.When you have multiple files in tempdb, you get another immediate header, PFS, GAM, and SGAM because all files will have the same structure and with multiple files we try and share the workload over these files.SQL Server spreads out object allocations across files in the same filegroup based on the proportional fill algorithm. We try to keep the same percentage of free space in each file within the file group so if all the files in the file group start at the same size and they stay the

(ColumnStore indexes, temporal tables, In Memory OLTP, etc.) all these new features require new metadata to be tracked, therefore the number of system tables we need to delete from is increasing, which makes the process more impactful.Temp table cache contention can be more prominent on larger SQL Server environments, larger core counts and as the size of the cache and the number of concurrent threads accessing the cache grows, this can introduce slower cache access as well as contention for the memory object associated with the cache.This condition can manifest in two different ways: CMEMTHREAD waits and SOS_CACHESTORE spinlock waits. To address temp table cache contention, it is recommended to track these wait conditions for evidence and ensure you have installed the latest cumulative updates (CUs) for SQL Server.Check out our Tech Community blog for more information on temp table caching in SQL Server.SQL Server 2022 tempdb improvementsIn SQL Server 2022 we have addressed the final common areas of contention by introducing concurrent GAM and SGAM updates similar to the Concurrent PFS updates.We use the Global Allocation Map (GAM) pages when we are looking for uniform extents and the Shared Global Allocation Map (SGAM) pages when we are looking for mixed extents in tempdb.In previous releases, under higher concurrent workloads we may have GAM contention where many different threads attempt to allocate extents on the same GAM page and each thread must first wait for another thread to release their UPDATE latch before they can obtain their own latch to allow them to make changes—so, we are just waiting in line.As can be seen in the workload example below, on SQL Server 2019 there is a wall of GAM contention driving over 123,000 counts of contention with the longest wait taking 949 milliseconds.The reason for this is that with the update latch, only one thread can modify the GAM page at a time, leading to contention. This is the primary reason we still need multiple data files and because of this contention, SQL Server throughput is decreased and workloads that require many updates to the GAM page will take longer to complete while the machine’s CPU will be underutilized. This contention is due to the workload volume and especially the use of repetitive create-and-drop operations.Starting with SQL Server 2016, we changed the default behavior to always allocate uniform extents when creating new objects in tempdb. This helped avoid most of the SGAM contention, but we still use mixed extents for Index Allocation Map (IAM) page allocations. IAM pages are used to track all the pages that belong to an object, so every object that gets created has at least one IAM page. For most workloads, these IAM page allocations don’t
