raibhurari shanduro 0.9.1 (MDBX) kushandiswa kwepamusoro-kuita, compact yakamisikidzwa kiyi-value dhatabhesi. Iyo libmdbx kodhi inogoverwa pasi perezinesi .
Iyo yazvino vhezheni ndeyekukanganisa pakati pechinangwa chekuburitsa yakagadzikana yenguva refu vhezheni 1.0 ine yakazara C ++ rutsigiro uye kusada kunonoka kuburitswa nekuda kwekusagadzirira kuomesa C ++ API itsva. Kuburitswa kwakaburitswa mhedzisiro yemwedzi ye9 yebasa rakanangana nekudzikamisa raibhurari nekuvandudza mashandisirwo ayo, uye zvakare inosanganisira yekutanga vhezheni. .
Libmdbx raibhurari haisi "forogo" chete, asi chizvarwa chakagadziridzwa zvakanyanya. - transaction yakamisikidzwa DBMS ye "kiyi-kukosha" kirasi yakavakirwa pa kunze , iyo inobvumira maitiro e-multi-threaded kuti ashande nemakwikwi uye anobudirira ane nzvimbo yakagovaniswa (isina-network) database pasina yakatsaurirwa server process. libmdbx zvakanyanya kugona kwemadzitateguru ayo, panguva imwe chete kubvisa kana kuderedza zvipingamupinyi. Panguva imwecheteyo, maererano nevagadziri, libmdbx inokurumidza uye yakavimbika zvakanyanya kupfuura LMDB.
libmdbx inoratidza , kunyatsoita serialization yekuchinja uye kusavharira kuverenga nekuyera mutsara muCPU cores. Mhedzisiro yekuyedza kuita (kutumira zvikumbiro zvakafanana zvekuverenga / kutsvaga mu1-2-4-8 tambo paCPU i7-4600U ine 2 emuviri cores mune 4-shinda HyperThread mode):
Misiyano yakakosha pakati peMDBX neLMDB:
- Chaizvoizvo, kutariswa kwakawanda kunobhadharwa kune kodhi mhando, API kuenderana, kuyedzwa uye otomatiki cheki.
- Yakanyanya kudzora panguva yekushanda, kubva pakutarisa ma parameter kusvika kuongororo yemukati yezvimiro zve database.
- Auto-compactification uye otomatiki dhatabhesi saizi manejimendi.
- Imwe dhatabhesi fomati ye32-bit uye 64-bit maassemblies.
- Kuyerwa kwemavhoriyamu emuenzaniso nemhando (range query estimation).
- Tsigiro yemakiyi akareba akapetwa kaviri uye saizi yepeji yemushandisi-inosarudzwa.
- Chishandiso chekutarisa kutendeseka kweiyo dhatabhesi chimiro nehumwe hunyanzvi hwekudzoreredza.
Hutsva hutsva uye kuvandudzwa mushure nekuunzwa kweshanduro 0.5 muna Ndira 2020:
- Iyo yakavhurika sisitimu yakagadzirwa kuti itsigire nekukurumidza uye mhinduro kumibvunzo. .
- Zvinopfuura gumi nemaviri zvikanganiso uye zvikanganiso zvakabviswa (ona. ).
- Mazhinji e typos uye zvikanganiso zvezviperengo zvakagadziriswa, uye akawanda magadzirirwo ekushongedza akaitwa.
- Mamiriro ekuedza akawedzerwa.
- Tsigiro yeIOS, Android, , , , ΠΈ .
- C++ API preview yakaburitswa mukati .
- Akavakirwa-mukati zvinyorwa muDooxygen fomati uye otomatiki chizvarwa .
- Kugadzira otomatiki kwezvinyorwa zvine zvinyorwa zvakabatanidzwa zvinopihwa.
- Yakawedzera tsigiro yekugadzirira kutengeserana uye macursors, mushandisi mamiriro ekutengeserana uye macursors.
- Dzimwe nzira dzakaitwa kudzora kutendeseka muB+ muti MVCC snapshots.
- Yakawedzerwa rutsigiro rwekutarisa MVCC snapshot yedhatabhesi, inowanikwa kuburikidza nechero meta peji ine kugona kushandura kupora.
- Yakaitwa tsigiro yekuvhurazve dhatabhesi kubva kune imwe maitiro ekuedza zvinangwa, nezvimwe.
- Yakaitwa otomatiki kugadzirisa kweMDBX_NOSUBDIR sarudzo paunovhura dhatabhesi.
- Akawedzera mabasa ekugadzira makiyi akazara kubva kune inoyangarara nzvimbo kukosha uye JavaScript "universal" nhamba.
- Pakazara, 430 shanduko dzakaitwa dzichibata 93 mafaira, kupfuura 25 zviuru mitsetse yakawedzerwa, kupfuura 8.5 zviuru mitsetse yakabviswa.
Inotevera kuvandudzwa kwe libmdbx inotarisa pane yekupedzisira C ++ API, kuwedzera kudzikamiswa kweiyo base kodhi, kuvandudza kushandiswa kweraibhurari, uye kurongedza kune yakakurumbira Linux kugovera. Pakati pezvakarongwa kuvandudzwa, zvakakosha kucherechedza kutsigirwa kwemakiyi mufomati .
