\u00d6nceki yaz\u0131lar\u0131m\u0131zda klavyeye ald\u0131\u011f\u0131m\u0131z Asp.NET Core \u2013 SignalR<\/a> yaz\u0131 serisinde SignalR teknolojisini s\u00fcrekli tekil mesajlar\u0131n iletimi \u00fczerine ele alm\u0131\u015ft\u0131k. Halbuki SignalR ayn\u0131 zamanda message streaming’i destekleyen bir yap\u0131ya sahiptir. Evet, iki konum aras\u0131ndaki ak\u0131\u015f s\u0131ras\u0131nda iletilecek mesaja dair t\u00fcm verilerin kullan\u0131labilir olmas\u0131n\u0131 beklemektense, mesaj\u0131n herbir par\u00e7as\u0131n\u0131n\/fragment’in kullan\u0131labilir hale gelmesiyle client’a ya da server’a par\u00e7a par\u00e7a g\u00f6nderilmesi m\u00fcmk\u00fcnd\u00fcr ve bu davran\u0131\u015f client’tan server’a ya da server’dan client’a olacak \u015fekilde streaming edilebilmektedir. Bu i\u00e7eri\u011fimizde SignalR teknolojisindeki mevzu bahis olan streaming davran\u0131\u015f\u0131n\u0131 masaya yat\u0131racak, Client-to-Server Streaming<\/em> ve Server-to-Client Streaming<\/em> olmak \u00fczere iki farkl\u0131 yakla\u015f\u0131m\u0131 tam teferruatl\u0131 bir \u015fekilde inceliyor olaca\u011f\u0131z.<\/p>\n

Streaming Nedir?<\/h3>\n
\u00d6ncelikle incelemede bulunaca\u011f\u0131m\u0131z streaming davran\u0131\u015f\u0131n\u0131n ne oldu\u011funu k\u0131saca izah ederek ba\u015flamakta fayda g\u00f6rmekteyim. Streaming; bir mesaj\u0131 hedef noktaya g\u00f6nderirken b\u00fct\u00fcnsel olarak g\u00f6ndermek yerine par\u00e7alar halinde g\u00f6ndermeyi ifade eden bir kavramd\u0131r. Bu mesaj, k\u00fc\u00e7\u00fck par\u00e7alara ayr\u0131lm\u0131\u015f b\u00fcy\u00fck bir nesne\/veri olabilece\u011fi gibi, her biri farkl\u0131 \u00f6\u011feler olan bir nesne\/veri koleksiyonu da olabilir.<\/p>\n
Misal olarak bir dosyan\u0131n server’dan client’a g\u00f6nderilmesi streaming ile ger\u00e7ekle\u015ftirilebilir. Dosyan\u0131n tamam\u0131n\u0131 bir seferde belle\u011fe y\u00fcklemek yerine, par\u00e7alan\u0131p g\u00f6nderilmesi bir streaming’dir ve bu davran\u0131\u015f ile hem bellek kullan\u0131m\u0131 daha etkili hale getirilebilir hem de i\u015flem s\u00fcresi daha da optimize edilebilir.<\/p>\n
Streaming Ne \u0130\u00e7in Kullan\u0131l\u0131r?<\/h3>\n
Mant\u0131ken iki farkl\u0131 blo\u011fun haberle\u015fme s\u00fcrecindeki zamansal ve performans a\u00e7\u0131s\u0131ndan do\u011fabilecek maliyetleri daha da t\u00f6rp\u00fclemek i\u00e7in diyebiliriz. D\u00fc\u015f\u00fcnsenize… Taray\u0131c\u0131 \u00fczerinden bir video izlemek istedi\u011finizde t\u00fcm videonun y\u00fcklenmesini mi bekliyorsunuz? E\u011fer b\u00f6yle bir durum s\u00f6z konusu olsayd\u0131 muhtemelen internetten bir film izleyebilmek i\u00e7in \u00f6ncelikle kayda de\u011fer s\u00fcre boyunca beklenmesi gerekecekti. Lakin videonun tamam\u0131n\u0131n y\u00fcklenmesini beklemek yerine, video k\u00fc\u00e7\u00fck par\u00e7alar halinde indirilmekte ve her par\u00e7a geldik\u00e7e izleme ger\u00e7ekle\u015ftirilmektedir. Bu \u015fekilde hem videonun adil bir s\u00fcre sonraki k\u0131sm\u0131 umrunuzda olmayacak hem de video izleme deneyimi tamamen kesintisiz olacakt\u0131r. Ee haliyle bu tarz bir durumda streaming davran\u0131\u015f\u0131 olmazsa olmazd\u0131r diyebiliriz.<\/p>\n
Ya da bir ba\u015fka \u00f6rnek vermemiz gerekirse e\u011fer Kapal\u0131 Devre Televizyon\/Closed-Circuit Television(CCTV)<\/em> kameralar\u0131nda video ak\u0131\u015f\u0131 s\u00fcreklidir. Yani kamera \u00e7ekim yaparken sadece veri par\u00e7alar\u0131n\u0131 al\u0131r ve g\u00f6nderir. \u0130\u015fte bu tarz senaryolarda da streaming tam anlam\u0131yla uygulanabilecek tek senaryodur diyebiliriz.<\/p>\n
SignalR’da Streaming Davran\u0131\u015f\u0131 Niye?<\/h3>\nEsas\u0131nda streaming deyince akla direkt gRPC<\/a> geliyor olabilir. Evet, bizler gRPC ile ba\u015far\u0131l\u0131 streaming davran\u0131\u015flar\u0131n\u0131 olduk\u00e7a h\u0131zl\u0131 ve performansl\u0131 bir \u015fekilde ger\u00e7ekle\u015ftirebiliyoruz. Amma velakin SignalR’da da real-time’da streaming davran\u0131\u015f\u0131n\u0131 direkt olarak sergilememiz gereken senaryolar olabilir. Tamam, SignalR ile birlikte gRPC’yi kullanarak streaming’i uygulayabiliriz. Ama salt bir \u015fekilde gRPC’ye ihtiya\u00e7 duyulmaks\u0131z\u0131n da bu ihtiyac\u0131 kar\u015f\u0131layabilmekteyiz.<\/p>\n
SignalR \u0130le Client-to-Server Streaming<\/h3>\n
Bu ak\u0131\u015f t\u00fcr\u00fcnde, client’tan server’a bir stream ba\u015flat\u0131l\u0131r ve bu stream bitene ve sonland\u0131r\u0131lana kadar mesaj g\u00f6nderme i\u015flemi devam eder. Server, mesajlar\u0131 ayn\u0131 \u00e7a\u011fr\u0131 ba\u011flam\u0131nda geldikleri s\u0131rayla edinecek ve mutlak veriyi b\u00fct\u00fcnsel olarak elde edene kadar bu s\u00fcre\u00e7 devam edecektir. Burada \u00f6nemli olan nokta \u015fudur ki, ak\u0131\u015f\u0131 kontrol eden client’t\u0131r. Tabi server, istedi\u011fi an ak\u0131\u015f\u0131 kapatabilecek bir yetene\u011fe sahiptir ancak normal bir \u015fekilde kapatman\u0131n s\u00f6z konusu olabilmesi i\u00e7in client taraf\u0131ndan bu eylemin gelmesi gerekmektedir.<\/p>\n
Client-to-Server Streaming i\u00e7in a\u015fa\u011f\u0131daki gibi Javascript \u00e7al\u0131\u015fmas\u0131 y\u00fcr\u00fct\u00fclebilir.<\/p>\n
\n
\r\n const subject = new Subject();\r\n this.hubConnection.send("UploadStream", subject);\r\n let count = 0;\r\n const intervalHandle = setInterval(() => {\r\n count++;\r\n subject.next(`Merhaba ${count}`);\r\n if (count === 10) {\r\n clearInterval(intervalHandle);\r\n subject.complete();\r\n }\r\n }, 1000);\r\n<\/pre>\n<\/div>\n
Burada yap\u0131lan \u00e7al\u0131\u015fmaya g\u00f6z atarsak e\u011fer ‘hubconnection’ \u00fczerinden send<\/code> fonksiyonuna \u00e7a\u011fr\u0131da bulunuyor ve sunucudaki UploadStream<\/em> metodunu tetikliyoruz ve b\u00f6ylece bir stream ba\u015flatm\u0131\u015f oluyoruz. Tabi dikkat ederseniz stream’de bir veri yay\u0131nlayabilmek i\u00e7in RxJS k\u00fct\u00fcphanesinde bulunan Subject<\/code> nesnesinden istifade ediyoruz. Ne zaman ki bu subject’i complete ederiz, o zaman olu\u015fturulan stream sonland\u0131r\u0131lm\u0131\u015f olacakt\u0131r.<\/p>\n
Peki hocam, bu client-to-server stream iste\u011finin kar\u015f\u0131lanmas\u0131 i\u00e7in sunucu taraf\u0131nda nas\u0131l bir \u00e7al\u0131\u015fma yapmal\u0131y\u0131z?<\/strong> diye sordu\u011funuzu duyar gibiyim… Client’tan ba\u015flat\u0131lan stream’i kar\u015f\u0131layabilmek i\u00e7in a\u015fa\u011f\u0131daki gibi ChannelReader<T><\/code> veya IAsyncEnumerable<T><\/code> t\u00fcrlerinden parametre alan metotlardan birinin bulundu\u011fu hub s\u0131n\u0131f\u0131n\u0131n tan\u0131mlanmas\u0131 yeterli olacakt\u0131r.<\/p>\n
