Mazuva mashoma apfuura kuburitswa kweiyo vhezheni itsva yeDBMS Nebula Graph 3.2 yakaziviswa, iyo yakagadzirirwa kuchengetedza nemazvo mahombe akabatana datasets anoumba girafu rinogona kuva nemabhiriyoni emanodhi uye matrillion ezvibatanidza.
iye DBMS inoshandisa chivakwa chakagoverwa pasina kugovera zviwanikwa (yakagovaniswa-hapana), izvo zvinoreva kutangwa kweyakazvimirira uye inozvikwanira yemifananidzo yemibvunzo yekugadzirisa maitiro uye akachengetwa ekuchengetedza maitiro. Metaservice inobata kurongeka kwekufamba kwedata uye kupihwa kwemeta ruzivo nezve girafu. Kuti uve nechokwadi chekuenderana kwedata, inoshandisa protocol yakavakirwa pane RAFT algorithm.
Zvikuru zvitsva zveNebula Girafu 3.2
Mune iyi vhezheni nyowani yeDBMS inounzwa, inosimbiswa kuti yakawedzerwa uyel rutsigiro rwekubvisa () basa kubvisa substring inoenderana neshoko rakapihwa, pamwe nekugadzirisa zvakagadziridzwa zvakaitwa kufaira rekugadzirisa.
Imwe shanduko inomira kubva mushanduro nyowani ndeyekuti yakawedzera optimization mitemo yekubvisa iyo AppendVertices opareta uye dzima edge uye vertex mafirita, pamwe nekudzikisa huwandu hwe data yakakopwa yeJOIN oparesheni, pamwe neyeTraverse uye AppendVertices vanoshanda.
Pamusoro peizvi, huwandu hwe data huchakopwa kumabasa emubatanidzwa kana kufambisa data kwakaderedzwa zvakare, mabasa akasiyana akaitwa kunatsiridza kuita uye optimized SHORTEST PATH uye SUBGRAPH.
Tinogona zvakare kuwana izvo ndangariro yekugovera yakagadziridzwa (uchishandisa Arena Allocator) uye kuti kukosha kwezvivakwa kunowanikwa kuburikidza nekunyoreswa kuderedza nguva inopedzwa nemibvunzo yezvivakwa.
Nezve kugadziriswa zvakaitwa mushanduro itsva iyi zvinotevera zvakataurwa:
- Fixed web service crash paunogamuchira mamwe mameseji akakosha ekurwisa.
- Yakagadziriswa yekuchengetedza sevhisi inoparara kana uchitarisa zvivakwa panguva imwe chete.
- Yakagadzika sevhisi yekuparara kana isa zita remupendero kureba richidarika muganhu.
- Yakagadzirisa kuparara kana uchigonesa concurrent query mode.
- Yakagadziriswa sevhisi yekuparara kana uchibvunza ma indexes ane NULL chivakwa.
- Yakagadzirisa kuputsika kana uchidonhedza zvinyorwa zvizere.
- Yakagadzika yekuchengetedza kuparara kana uchidzima vertex uye mupendero tsanangura vid kupfuura zvatakatsanangura mudenga.
- Yakagadziriswa bug yakakonzera kuti daemon yakamira ibude mushure mekutangwazve.
- Yakagadziriswa nyaya apo iyo JoinDots fomati inotsanangura mhedzisiro yanga isiriyo yeGraphViz online turusi, zvichikonzera kushandurwa kaviri kubva kuJSON.
- Yakagadziriswa bug mumivhunzo yemidziyo. Kushandiswa kwemapoinzi ari mupepa rehurukuro kwava kuremara.
- Yakagadzirisa bug kuti pakanga pasina nhamba pasi pemamiriro ekushandisa indexes.
- Yakagadziriswa bug iyo cluster nguva zone yakasiyana.
Maitiro ekuisa Nebula Girafu pane Linux?
Kune avo vanofarira kugona kuisa iyi DBMS pane yavo system, vanogona kuzviita kutevera mirairo iyo yatinogovana pazasi.
Kana iwe uine Centos 7 pasuru iwe yaunofanirwa kurodha pasi inotevera. Kuti uite izvi unofanirwa kuvhura terminal pane yako system uye mairi uchanyora unotevera kuraira:
wget https://oss-cdn.nebula-graph.com.cn/package/3.2.0/nebula-graph-3.2.0.el7.x86_64.rpm
Kana iwe ukashandisa masendi 8, ipapo pasuru yaunoda kurodha ndeiyi:
wget https://oss-cdn.nebula-graph.com.cn/package/3.2.0/nebula-graph-3.2.0.el8.x86_64.rpm
Nguva muchiitiko cheavo vari vashandisi Ubuntu 18.04 LTS
wget https://oss-cdn.nebula-graph.com.cn/package/3.2.0/nebula-graph-3.2.0.ubuntu1804.amd64.deb
Kana kune avo vari vashandisi veUbuntu 20.04 LTS kana kupfuura, vanogona kudhawunirodha nemurairo unotevera:
wget https://oss-cdn.nebula-graph.com.cn/package/3.2.0/nebula-graph-3.2.0.ubuntu2004.amd64.deb
Kuti uite kuiswa kwepakeji kurodha pasi iwe unogona kuzviita neyako yaunoda package maneja kana iwe unogona kuzviita kubva kune terminal nekutaipa mumwe weinotevera mirairo.
Mune mamiriro emapakeji ye CentOS:
sudo rpm -ivh nebula*.rpm
Panguva yeiyo kesi yepakeji yeUbuntu:
sudo dpkg -i nebula*.deb
Pakupedzisira, kana iwe uri mushandisi weArch Linux unogona kuisa iyo DBMS nemirairo inotevera:
sudo pacman -S nebula
Kuti udzidze zvakawanda nezvekushandisa kwayo, kuvhurwa kwemasevhisi nevamwe, unogona kubvunza ruzivo rwese urwu Mune inotevera chinongedzo.
