Kafka remained with the company until , when a bout with tuberculosis forced him to take a sick leave and to eventually retire in At work Kafka was a popular employee, easy to socialize with and seen as somebody with a good sense of humor. But his personal life still raged with complications.
His inhibitions and insecurities plagued his relationships. Twice he was engaged to marry his girlfriend, Felice Bauer, before the two finally went their separate ways in Later, Kafka later fell in love with Dora Dymant Diamant , who shared his Jewish roots and a preference for socialism. Amidst Kafka's increasingly dire health, the two fell in love and lived together in Berlin.
Their relationship largely centered on Kafka's illnesses. For many years, even before he contracted tuberculosis, Kafka had not been well. Constantly strained and stressed, he suffered from migraines, boils, depression, anxiety and insomnia. Kafka and Dora eventually returned to Prague. In an attempt to overcome his tuberculosis, Kafka traveled to Vienna for treatment at a sanatorium. He died in Kierling, Austria, on June 3, While Kafka strove to earn a living, he also poured himself into his writing work.
An old friend named Max Brod would prove crucial in supporting Kafka's literary work both during his life and long after it. Kafka's celebrity as a writer only came after his death. During his lifetime, he published just a sliver of his overall work.
His most popular and best-selling short story, "The Metamorphosis," was completed in and published in The story was written from Kafka's third-floor room, which offered a direct view of the Vltava River and its toll bridge. Kafka followed up "The Metamorphosis" with Mediation , a collection of short stories, in , and "Before the Law," a parable within his novel The Trial , written between and Even with his worsening health, Kafka continued to write.
In he completed "The Judgment," which spoke directly about the relationship he shared with his father. In , an ill but still working Kafka finished A Hunger Artist , which features four stories that demonstrate the concise and lucid style that marked his writing at the end of his life. But Kafka, still living with the demons that plagued with him self-doubt, was reluctant to unleash his work on the world.
He requested that Brod, who doubled as his literary executor, destroy any unpublished manuscripts. Fortunately, Brod did not adhere to his friend's wishes and in published The Trial , a dark, paranoid tale that proved to be the author's most successful novel. The story centers on the life of Joseph K. In , at the home of his lifelong friend Max Brod, Kafka met Felice Bauer, who lived in Berlin and worked as a representative for a dictaphone company.
Over the next five years they corresponded a great deal, met occasionally, and twice were engaged to be married. Their relationship finally ended in In , Kafka began to suffer from tuberculosis, which would require frequent convalescence during which he was supported by his family, most notably his sister Ottla. Despite his fear of being perceived as both physically and mentally repulsive, he impressed others with his boyish, neat, and austere good looks, a quiet and cool demeanor, obvious intelligence and dry sense of humor.
In , he briefly moved to Berlin in the hope of distancing himself from his family's influence to concentrate on his writing. In Berlin, he lived with Dora Diamant, a year-old kindergarten teacher from an orthodox Jewish family, who was independent enough to have escaped her past in the ghetto. Dora became his lover, and influenced Kafka's interest in the Talmud. It is generally agreed that Kafka suffered from clinical depression and social anxiety throughout his entire life.
He also suffered from migraines, insomnia, constipation, boils, and other ailments, all usually brought on by excessive stresses and strains. He attempted to counteract all of this by a regimen of naturopathic treatments, such as a vegetarian diet.
However, Kafka's tuberculosis worsened; he returned to Prague, then went to a sanatorium near Vienna for treatment, where he died on June 3, The Project. General Bibliography. Kafka promises to maintain backward compatibility with older clients, and many languages are supported. Avro and the Schema Registry allow complex records to be produced and read by clients in many programming languages and allow for the evolution of the records.
Kafka is truly polyglot. Kafka allows you to build real-time streaming data pipelines. Kafka enables in-memory microservices i. Kafka allows you to build real-time streaming applications that react to streams to do real-time data analytics, transform, react, aggregate, join real-time data flows, and perform CEP complex event processing.
You can use it with microservices in-memory and actor systems to implement in-memory services external commit log for distributed systems. You can use Kafka to replicate data between nodes, to re-sync for nodes, and to restore state. While Kafka is mostly used for real-time data analytics and stream processing, you can also use it for log aggregation, messaging, click-stream tracking, audit trails, and much more.
In a world where data science and analytics are a big deal, capturing data to feed into your data lakes and real-time analytics systems is also a big deal.
And since Kafka can hold up to these kinds of strenuous use cases, Kafka is a big deal. Kafka acts like high-speed file system for commit log storage and replication. These characteristics make Kafka useful for all manners of applications. Records written to Kafka topics are persisted to disk and replicated to other servers for fault-tolerance. Since modern drives are fast and quite large, this fits well and is very useful. Kafka Producers can wait on acknowledgment, so messages are durable as the producer write not complete until the message replicates.
The Kafka disk structure scales well. Modern disk drives have very high throughput when writing in large streaming batches. Also, Kafka clients and consumers can control read position offset , which allows for use cases like replaying the log if there was a critical bug i.
And since offsets are tracked per consumer group, which we talk about in this Kafka architecture article, consumers can be quite flexible i. Kafka clusters retain all published record. You can set time-based limits configurable retention period , size-based limits configurable based on size , or compaction keeps the latest version of record using key.
You can, for example, set a retention policy of three days or two weeks or a month. The records in the topic log are available for consumption until discarded by time, size, or compaction. The consumption speed not impacted by size as Kafka always writes to the end of the topic log. Introduction to Apache Kafka [Tutorial]. See the original article here.
