IMicrosoft ityhilwe esanda kukhutshwa ikhowudi yemvelaphi yenjini yokugcina eyandisiweyo (aka JET Blue) kwaye iyafumaneka kwiGitHub.
Kumaxwebhu achazwe sisixhobo, iMicrosoft ichaza ukuba Injini yoGcino eyandisiweyo (OKO) Itekhnoloji yokugcinwa kwe-ISAM ephambili (isalathiso kunye nendlela yokufikelela ngokulandelelana). I-ESE yenza ukuba usetyenziso lugcine kwaye lubuyise idatha yeetafile usebenzisa isikhombisi esilandelanayo okanye esalathisiweyo.
Ixhasa ii-schemas ezichaziweyo, kubandakanya iitafile ezibanzi ezinamakholamu amaninzi, iikholamu ezinemigangatho emininzi, kunye ne-sparse, ii-indexes ezityebileyo, kwaye yenza ukuba ukonwabela imeko yedatha engaguqukiyo ngokuhlaziya kunye nokufumana idatha eqhutyiweyo. Inkqubo yokubuyiselwa kweentlekele ibonelelwe ukugcina ukungqinelana kwedatha kwimeko apho inkqubo isilele.
Ukubonelela ngokuThengisanayo okungaguqukiyo kweAtomic (ACID) kwidatha kunye ne-schema kusetyenziswa irejista yokubhala phambili kunye nemodeli yokwahlulahlula umfanekiso. Intengiselwano kwi-ESE ngokufanayo, eyenza i-ESE iluncedo kwizicelo zeseva.
Ngapha koko, ayisindi, eyenza ukuba iluncedo kwizicelo ezenza imisebenzi encedisayo.
Intengiselwano kwi-ESE ngokufanayo, eyenza i-ESE iluncedo kwizicelo zeseva. Idatha egciniweyo yokwandisa ukufikelela kwidatha yokusebenza okuphezulu. Ngapha koko, ayisindi, eyenza ukuba iluncedo kwizicelo ezenza imisebenzi encedisayo.
ESE yenzelwe ukusetyenziswa kwizicelo ezifuna ukugcinwa kwedatha eyakhiwe ngokukhawuleza kunye / okanye ukukhanya okulula, apho ukufikelela kwiifayile ezingavuthiyo okanye irejista ingaxhasi ukuxhonywa okanye ubungakanani bedata kwiimfuno zesicelo.
Isetyenziswa zizicelo ezingaze zigcine ngaphezulu kwe-1 megabyte yedatha, kwaye isetyenzisiwe kwizicelo ezinedatha kwiimeko ezigqithileyo ze-1 terabyte kwaye zihlala ngaphezulu kwe-50 gigabytes.
Injini yoGcino eyandisiweyo licandelo leWindows elaziswe kwiWindows 2000. Ayisiyiyo yonke imisebenzi okanye ii-API ezifumanekayo kuzo zonke iinguqulelo zeendlela zokusebenza zeWindows.
I-ESE ibonelela ngemowudi yokugcina indlela yokusebenza yomsebenzisi elawula idatha ngaphakathi kweefayile ezicwangcisiweyo ezibini ezifikelelekayo kwiiWindows APIs. I-ESE inokufikelelwa nge-DLL Elayishwe ngqo kwinkqubo yesicelo; Injini yedatha ayifuni okanye ibonelele ngayo nayiphi na indlela yokufikelela ekude.
Nangona i-ESE ayinayo indlela yokufikelela ekude okanye enqamlezileyo, Iifayile zedatha oyisebenzisayo zinokuhanjiswa ukude usebenzisa iServer yoMyalezo weBhloko (SMB) nge-Windows APIs, kodwa oku akucetyiswa.
Injini yokuGcina eyandisiweyo (i-ESE) yindlela ethembekileyo yokungena (ISAM) yokugcina iteknoloji kwaye ibeyinxalenye ebalulekileyo yeWindows ngaphezulu kwekota yenkulungwane. Iqale ukuvela kwiWindows NT 3.51 kunye noTshintshiselwano nge-4.0 ngaphambi kokuqhubeka nobomi obude namhlanje Windows 10.
Izinto ezinje ngoKhangelo lweWindows okanye usetyenziso olufana noTshintshiselwano, "gcina kwaye ufumane idatha yeetafile usebenzisa isalathiso okanye isalathiso sokuhambisa isikhombisi."
Injini yokuGcina eyandisiweyo (ESE) yenye yeekhowudi ezinqabileyo ezinobomi obungaphezulu kweminyaka engama-25. Ukuqala ukukhutshwa kwiWindows NT 3.51 kwaye kungekudala emva koko kwi-Exchange 4.0, yaphinda yabhalwa kabini kwii-90s, kwaye yahlaziywa kakhulu kule minyaka ingamashumi amabini izayo, ihlala isisiseko seMicrosoft ukuza kuthi ga kulo mhla.
Ibaleka kumakhulu amawaka oomatshini kunye nezigidi zeediski zeeseva ezinkulu zokugcina i-Ofisi ezingama-365. Ikwaqhuba kwiinkqubo ezinkulu ze-SMP ezine-TB yememori yokuhanjiswa okukhulu kwe-Active Directory.
Ngelixa uninzi lwezicelo ezisebenzisayo zingadluli uphawu lwe-1MB, "iimeko ezigabadeleyo" zodlula i-1TB.
Ngokubhekisele kwinto ebekwe kwi-GitHub, abasebenzisi baya kudana kukuba izimvo zisusiwe (nangona ilungelo lokushicilela kunye nelayisensi ye-MIT ikhona).
Okokugqibela ukuba unomdla wokufumana ikhowudi yemvelaphi, ungayenza kule khonkco.
