In its May 2020 report on MongoDB version 4.2.6, Jepsen wrote that MongoDB had only mentioned tests that version 3.6.4 had passed, and that version had 4.2.6 introduced more problems. Jepsen's test summary reads in part: Jepsen evaluated MongoDB version 4.2.6, and found that even at

756-492: A PaaS provider to run applications in an open-source environment, such as Google App Engine . Some open platforms let the developer use any programming language, database, operating system or server to deploy their applications. There are various types of PaaS providers. All offer application hosting and a deployment environment, along with various integrated services. Services offer varying levels of scalability and maintenance. Developers can write an application and upload it to

864-598: A PaaS that supports their software language of choice, and the application runs on that PaaS. The UK Government encourages departments to make use of public cloud solutions as a first option. PaaS is in use within UK Government but the technology community within government notes that PaaS providers may restrict the software, languages and interfaces they are willing to support. The Government operated its own GOV.UK PaaS service from 2015 until 2023, but this has now been decommissioned. Russia Russia , or

In

1080-1159: A company's on-premises data center , or in a public cloud. Once the software is installed on one or more machines, the private PaaS arranges the application and database components into a single hosting platform. Hybrid PaaS is typically a deployment consisting of a mix of public and private deployments. A communications platform as a service (CPaaS) is a cloud-based platform that enables developers to add real-time communications features (voice, video, and messaging) in their own applications without building back-end infrastructure and interfaces. Also, CPaaS and hardware and software specifications are specifically designed to support (tele)communications applications. These applications and their usage are much more sensitive to jitter, latency and packet losses. Hosted PBX , cellular networks, (near real-time) applications typically are deployed on CPaaS platforms. Initiated in 2012, mobile PaaS (mPaaS) provides development capabilities for mobile app designers and developers. The Yankee Group identified mPaaS as one of its themes for 2014. Open PaaS does not include hosting but provides open-source software allowing

1188-442: A copy of the data of the primary using built-in replication. When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary. Secondaries can optionally serve read operations, but that data is only eventually consistent by default. If the replicated MongoDB deployment only has a single secondary member, a separate daemon called an arbiter must be added to

Prior to Slavic migration, that territory

1620-468: A pipeline, analogous to Unix pipes . The aggregation framework includes the $ lookup operator, which can join documents from multiple collections, as well as statistical operators such as standard deviation. JavaScript can be used in queries, aggregation functions (such as MapReduce ) and sent directly to the database to be executed. MongoDB supports fixed-size collections called capped collections. This type of collection maintains insertion order and, once

1728-421: A random sample of results of a given size. Fields in a MongoDB document can be indexed with primary and secondary indices. MongoDB provides high availability with replica sets. A replica set consists of two or more copies of the data. Each replica-set member may act in the role of primary or secondary replica at any time. All writes and reads are done on the primary replica by default. Secondary replicas maintain

Another German failure was the Siege of Leningrad , in which the city was fully blockaded on land between 1941 and 1944 by German and Finnish forces, and suffered starvation and more than a million deaths, but never surrendered. Soviet forces steamrolled through Eastern and Central Europe in 1944–1945 and captured Berlin in May 1945. In August 1945,

2592-765: The Brusilov Offensive of the Imperial Russian Army almost completely destroyed the Austro-Hungarian Army . However, the already-existing public distrust of the regime was deepened by the rising costs of war, high casualties , and rumors of corruption and treason. All this formed the climate for the Russian Revolution of 1917, carried out in two major acts. In early 1917, Nicholas II was forced to abdicate ; he and his family were imprisoned and later executed during

2700-475: The Congress of Vienna , which defined the map of post-Napoleonic Europe.

Subsequently, the Germans were dealt major defeats first at the Battle of Stalingrad in the winter of 1942–1943, and then in

7992-406: The majority concern (w:majority) from MongoDB 5.0." MongoDB Inc. hosts an annual developer conference that has been called MongoDB World or MongoDB.live. Platform as a service Platform as a service ( PaaS ) or application platform as a service ( aPaaS ) or platform-based service is a cloud computing service model where users provision, instantiate, run and manage a modular bundle of

8100-530: The map-reduce function and single-purpose aggregation methods. Map-reduce can be used for batch processing of data and aggregation operations. However, according to MongoDB's documentation, the aggregation pipeline provides better performance for most aggregation operations. The aggregation framework enables users to obtain results similar to those returned by queries that include the SQL GROUP BY clause. Aggregation operators can be strung together to form

8208-686: The meantime, both the Bolsheviks and White movement carried out campaigns of deportations and executions against each other, known respectively as the Red Terror and White Terror . By the end of the violent civil war, Russia's economy and infrastructure were heavily damaged, and as many as 10 million perished during the war, mostly civilians. Millions became White émigrés , and the Russian famine of 1921–1922 claimed up to five million victims. On 30 December 1922, Lenin and his aides formed

8316-609: The more recently coined noun россиянин , rossiianyn , "Russian" in the sense of citizen of the Russian state. According to the Primary Chronicle , the word Rus' is derived from the Rus' people , who were a Swedish tribe, and where the three original members of the Rurikid dynasty came from. The Finnish word for Swedes, ruotsi , has the same origin. Later archeological studies mostly confirmed this theory. The first human settlement on Russia dates back to

8424-542: The name Rus ' , Росия ( Rosiya ), was borrowed from the Greek term and first attested in 1387. The name Rossiia appeared in Russian sources in the late 15th century, but until the end of the 17th century the country was more often referred to by its inhabitants as Rus ' , the Russian land ( Russkaia zemlia ), or the Muscovite state ( Moskovskoe gosudarstvo ), among other variations. In 1721, Peter

8532-641: The north-east. Led by Prince Alexander Nevsky , Novgorodians repelled the invading Swedes in the Battle of the Neva in 1240, as well as the Germanic crusaders in the Battle on the Ice in 1242. Kievan Rus' finally fell to the Mongol invasion of 1237–1240, which resulted in the sacking of Kiev and other cities, as well as the death of a major part of the population. The invaders, later known as Tatars , formed

8640-620: The obstinate resistance in combination with the bitterly cold Russian winter led to a disastrous defeat of invaders, in which the pan-European Grande Armée faced utter destruction. Led by Mikhail Kutuzov and Michael Andreas Barclay de Tolly , the Imperial Russian Army ousted Napoleon and drove throughout Europe in the War of the Sixth Coalition , ultimately entering Paris. Alexander I controlled Russia's delegation at

8748-654: The official line. The continued internal struggle in the Bolshevik party culminated in the Great Purge . Under Stalin's leadership, the government launched a command economy , industrialisation of the largely rural country , and collectivisation of its agriculture . During this period of rapid economic and social change, millions of people were sent to penal labour camps , including many political convicts for their suspected or real opposition to Stalin's rule; and millions were deported and exiled to remote areas of

8856-459: The pages load. The use of lock yielding expanded greatly in version 2.2. Until version 3.3.11, MongoDB could not perform collation -based sorting and was limited to bytewise comparison via memcmp , which would not provide correct ordering for many non-English languages when used with a Unicode encoding. The issue was fixed on August 23, 2016. Prior to MongoDB 4.0, queries against an index were not atomic. Documents that were updated while queries

8964-419: The public cloud, private and hybrid PaaS options (managed by internal IT departments) were created. PaaS provides an environment for developers and companies to create, host and deploy applications, saving developers from the complexities of infrastructure (setting up, configuring and managing elements such as servers and databases). PaaS can improve the speed of developing an app, and allow its user to focus on

9072-589: The rivalry between the two major European empires came to be known as the Great Game . The late 19th century saw the rise of various socialist movements in Russia. Alexander II was assassinated in 1881 by revolutionary terrorists. The reign of his son Alexander III (1881–1894) was less liberal but more peaceful. Under last Russian emperor, Nicholas II (1894–1917), the Revolution of 1905

9180-428: The safe use of MongoDB transactions. On May 26, Jepsen updated the report to say: "MongoDB identified a bug in the transaction retry mechanism which they believe was responsible for the anomalies observed in this report; a patch is scheduled for 4.2.8." The issue has been patched as of that version, and "Jepsen criticisms of the default write concerns have also been addressed, with the default write concern now elevated to

9288-876: The seat of the Metropolitan of the Russian Orthodox Church moved to Moscow in 1325, its influence increased. Moscow's last rival, the Novgorod Republic , prospered as the chief fur trade centre and the easternmost port of the Hanseatic League . Led by Prince Dmitry Donskoy of Moscow, the united army of Russian principalities inflicted a milestone defeat on the Mongol-Tatars in the Battle of Kulikovo in 1380. Moscow gradually absorbed its parent duchy and surrounding principalities, including formerly strong rivals such as Tver and Novgorod . Ivan III ("the Great") threw off

9396-452: The service engineering aspects, PaaS offerings include mechanisms for service management, such as monitoring, workflow management, discovery and reservation. The advantages of PaaS are primarily that it allows for higher-level programming with dramatically reduced complexity; the overall development of the application can be more effective, as it has built-in/self up-and-down ramping infrastructure resources; and maintenance and enhancement of

9504-428: The set. It has the single responsibility of resolving the election of the new primary. As a consequence, an ideal distributed MongoDB deployment requires at least three separate servers, even in the case of just one primary and one secondary. MongoDB scales horizontally using sharding . The user chooses a shard key, which determines how the data in a collection will be distributed. The data is split into ranges (based on

9612-512: The shard key) and distributed across multiple shards, which are masters with one or more replicas. Alternatively, the shard key can be hashed to map to a shard–enabling an even data distribution. MongoDB can run over multiple servers, balancing the load or duplicating data to keep the system functional in case of hardware failure. MongoDB can be used as a file system , called GridFS , with load-balancing and data-replication features over multiple machines for storing files. This function, called

9720-581: The software publicly available as part of a "service" must make the service's entire source code (insofar that a user would be able to recreate the service themselves) available under this license. By contrast, the AGPL only requires the source code of the licensed software to be provided to users when the software is conveyed over a network. The SSPL was submitted for certification to the Open Source Initiative but later withdrawn. In January 2021,

9828-802: The specified size has been reached, behaves like a circular queue . MongoDB supports multi-document ACID transactions since the 4.0 release in June 2018. The MongoDB Community Edition is free and available for Windows, Linux and macOS. MongoDB Enterprise Server is the commercial edition of MongoDB and is available as part of the MongoDB Enterprise Advanced subscription. MongoDB is also available as an on-demand, fully managed service. MongoDB Atlas runs on AWS, Microsoft Azure and Google Cloud Platform. On March 10, 2022, MongoDB warned its users in Russia and Belarus that their data stored on

9936-498: The stable release 4.0.4, the software's license changed from AGPL 3.0 to SSPL. On October 30, 2019, MongoDB teamed with Alibaba Cloud to offer Alibaba Cloud customers a MongoDB-as-a-service solution. Customers can use the managed offering from Alibaba's global data centers. MongoDB supports field, range query and regular-expression searches. Queries can return specific fields of documents and also include user-defined JavaScript functions. Queries can also be configured to return

10044-656: The state of the Golden Horde , which ruled over Russia for the next two centuries. Only the Novgorod Republic escaped foreign occupation after it agreed to pay tribute to the Mongols. Galicia-Volhynia would later be absorbed by Lithuania and Poland , while the Novgorod Republic continued to prosper in the north. In the northeast, the Byzantine-Slavic traditions of Kievan Rus' were adapted to form

10152-533: The strongest levels of read and write concern, it failed to preserve snapshot isolation. Instead, Jepsen observed read skew, cyclic information flow, duplicate writes, and internal consistency violations. Weak defaults meant that transactions could lose writes and allow dirty reads, even downgrading requested safety levels at the database and collection level. Moreover, the snapshot read concern did not guarantee snapshot unless paired with write concern majority—even for read-only transactions. These design choices complicate

10260-523: The time Chechen separatists declared independence in the early 1990s, an intermittent guerrilla war was fought between the rebel groups and Russian forces. Terrorist attacks against civilians were carried out by Chechen separatists, claiming the lives of thousands of Russian civilians. After the dissolution of the Soviet Union, Russia assumed responsibility for settling the latter's external debts. In 1992, most consumer price controls were eliminated, causing extreme inflation and significantly devaluing

The Khazars , who were of Turkic origin , ruled the steppes between the Caucasus in the south, to the east past the Volga river basin, and west as far as Kyiv on the Dnieper river until the 10th century. After them came the Pechenegs who created

10908-599: Was developed in 2005, had a beta launch in March 2006 and a public launch at EuroOSCON in 2006. At the time of its closure, Zimki had several thousand developer accounts. It had demonstrated the technical viability of Platform as a Service, but also provided the first example of the perils of being dependent on a single provider. This was highlighted when the CEO ( Simon Wardley , known for Wardley maps ) announced at OSCON 2007 that Zimki would no longer be open-sourced and discussed

11016-670: Was dissolved by the All-Russian Central Executive Committee . An alternative socialist establishment co-existed, the Petrograd Soviet , wielding power through the democratically elected councils of workers and peasants, called soviets .

The establishment of the first East Slavic states in the 9th century coincided with the arrival of Varangians , the Vikings who ventured along the waterways extending from the eastern Baltic to the Black and Caspian Seas. According to the Primary Chronicle ,

11448-410: Was running could be missed. The introduction of the snapshot read concern in MongoDB 4.0 eliminated this risk. MongoDB claimed that version 3.6.4 had passed "the industry's toughest data safety, correctness, and consistency tests" by Jepsen, and that "MongoDB offers among the strongest data consistency, correctness, and safety guarantees of any database available today." Jepsen, which describes itself as

During the war, Soviet civilian and military death were about 26–27 million , accounting for about half of all World War II casualties . The Soviet economy and infrastructure suffered massive devastation, which caused the Soviet famine of 1946–1947 . However, at the expense of a large sacrifice, the Soviet Union emerged as

11664-695: Was triggered by the humiliating failure of the Russo-Japanese War . The uprising was put down, but the government was forced to concede major reforms ( Russian Constitution of 1906 ), including granting freedoms of speech and assembly , the legalisation of political parties, and the creation of an elected legislative body, the State Duma . In 1914, Russia entered World War I in response to Austria-Hungary 's declaration of war on Russia's ally Serbia , and fought across multiple fronts while isolated from its Triple Entente allies.
