Aloha! E pili ana kēia ʻatikala pehea mākou i kākau ai i kahi ʻōnaehana nānā hou no mākou iho. He ʻokoʻa ia mai nā mea i loaʻa i kona hiki ke loaʻa i nā metric synchronous kiʻekiʻe a me ka hoʻohana haʻahaʻa haʻahaʻa loa. Hiki i ka helu koho balota ke hiki i ka 0.1 milliseconds me ka pololei synchronization ma waena o nā metric o 10 nanoseconds. Loaʻa nā waihona binary āpau i 6 megabytes.
No ka papahana
Loaʻa iā mākou kahi huahana kikoʻī. Hoʻopuka mākou i kahi hopena piha no ka hōʻuluʻulu ʻana i ka throughput a me ka hoʻomanawanui hewa o nā ala hoʻoili ʻikepili. ʻO kēia ka manawa he nui nā kaha, e ʻōlelo kākou ʻo Operator1 (40Mbit/s) + Operator2 (30Mbit/s)+ ʻO kekahi mea ʻē aʻe (5 Mbit/s), ʻo ka hopena he hoʻokahi paʻa a wikiwiki hoʻi, ʻo ka wikiwiki o ia mea. keia: (40+ 30+5)x0.92=75×0.92=69 Mbit/s.
Ke koi ʻia nei nā ʻano hana inā ʻaʻole lawa ka hiki o ke kahawai hoʻokahi. No ka laʻana, ka lawe ʻana, nā ʻōnaehana nānā wikiō a me nā wikiō wikiō maoli, hoʻolaha ʻia o ke kīwī ola a me nā hoʻolaha lekiō, nā keʻena kūloko kahi i waena o nā mea lawelawe kelepona aia wale nō nā ʻelele o ka Big Four a ʻaʻole lawa ka wikiwiki o ka modem / channel. .
No kēlā me kēia mau wahi, hana mākou i kahi laina kaʻawale o nā mea hana, akā ʻaneʻane like kā lākou ʻāpana polokalamu a ʻo kahi ʻōnaehana nānā kiʻekiʻe kekahi o kāna mau modula nui, me ka ʻole o ka hoʻokō pono ʻana i hiki ʻole ai ka huahana.
I loko o nā makahiki he nui, ua hoʻokō mākou i ka hana ʻana i kahi ʻōnaehana mākaʻikaʻi multi-level, wikiwiki, cross-platform a me ka māmā. ʻO kēia ka mea a mākou e makemake ai e kaʻana like me ko mākou kaiāulu mahalo.
Ka hoʻokumu ʻana i ka pilikia
Hāʻawi ka ʻōnaehana kiaʻi i nā ana o nā papa ʻokoʻa ʻelua: nā metric manawa maoli a me nā mea ʻē aʻe. ʻO ka ʻōnaehana nānā wale nō nā koi penei:
- ʻO ka loaʻa pinepine ʻana o ka manawa maoli a me kā lākou hoʻololi ʻana i ka ʻōnaehana hoʻokele kamaʻilio me ka kali ʻole.
ʻAʻole koʻikoʻi wale ke alapine kiʻekiʻe a me ka hoʻonohonoho ʻana o nā metric like ʻole, he mea koʻikoʻi ia no ka nānā ʻana i ka entropy o nā ala hoʻoili ʻikepili. Inā he 30 milliseconds ka lōʻihi o ka hoʻouna ʻikepili i hoʻokahi, a laila, ʻo ka hewa o ka hoʻonohonoho ʻana ma waena o nā koena o hoʻokahi milliseconds e alakaʻi i ka hoʻohaʻahaʻa ʻana i ka wikiwiki o ke kahawai hopena ma kahi o 5%. Inā kuhi hewa mākou i ka manawa ma ka 1 millisecond ma waena o nā kahawai 4, hiki ke hāʻule ka wikiwiki i ka 30%. Eia kekahi, hoʻololi koke ka entropy i nā kahawai, no laila inā mākou e ana iā ia ma mua o hoʻokahi manawa i kēlā me kēia 0.5 milliseconds, ma nā ala wikiwiki me kahi lohi liʻiliʻi e loaʻa iā mākou ka wikiwiki wikiwiki. ʻOiaʻiʻo, ʻaʻole pono ia pololei no nā metric āpau a ʻaʻole i nā kūlana āpau. I ka 500 milliseconds ka lōʻihi o ke kahawai, a hana mākou me ia, a laila ʻaʻole ʻike ʻia kahi hewa o 1 milliseconds. Eia kekahi, no nā ʻōnaehana kākoʻo ola, loaʻa iā mākou nā helu koho balota a me ka hoʻonohonoho ʻana o 2 kekona, akā pono e hiki i ka ʻōnaehana nānā pono ke hana me nā helu koho kiʻekiʻe kiʻekiʻe a me ka synchronization ultra-pcise o nā ana. - ʻO ka liʻiliʻi liʻiliʻi o ka hoʻohana ʻana i nā kumuwaiwai a me kahi waihona hoʻokahi.
Hiki i ka mea hoʻopau ke lilo i mea paʻakikī ma luna o ka papa e hiki ke nānā i ke kūlana ma ke alanui a i ʻole ke alakaʻi ʻana i ka hoʻopaʻa ʻana i ka biometric o nā kānaka, a i ʻole ka lolouila papa hoʻokahi pālima i hoʻokomo ʻia e kahi koa kūikawā ma lalo o kona pale kino e hoʻouna i nā wikiō i loko. manawa maoli i nā kūlana kamaʻilio maikaʻi ʻole. ʻOiai ke ʻano like ʻole o ka hoʻolālā ʻana a me ka mana helu, makemake mākou e loaʻa ka waihona polokalamu like. - ʻO ka hoʻolālā ʻumbrella
Pono e hōʻiliʻili a hōʻuluʻulu ʻia nā metric ma ka hāmeʻa hoʻopau, loaʻa kahi waihona kūloko, a ʻike ʻia i ka manawa maoli a me ka retrospectively. Inā loaʻa kahi pilina, e hoʻoili i ka ʻikepili i ka ʻōnaehana nānā kikowaena. Inā ʻaʻohe pili, pono e hōʻiliʻili ka laina hoʻouna a ʻaʻole hoʻopau i ka RAM. - API no ka hoʻohui ʻana i ka ʻōnaehana nānā o ka mea kūʻai aku, no ka mea, ʻaʻohe mea e pono ai nā ʻōnaehana nānā. Pono ka mea kūʻai aku e hōʻiliʻili i ka ʻikepili mai nā mea hana a me nā pūnaewele i hoʻokahi nānā.
He aha lā
I mea e kaumaha ʻole ai i ka heluhelu lōʻihi loa, ʻaʻole wau e hāʻawi i nā hiʻohiʻona a me nā ana o nā ʻōnaehana nānā āpau. E alakaʻi kēia i kahi ʻatikala ʻē aʻe. E ʻōlelo wale wau ʻaʻole hiki iā mākou ke ʻike i kahi ʻōnaehana nānā e hiki ke lawe i ʻelua metric i ka manawa like me kahi hewa o ka liʻiliʻi ma mua o 1 millisecond a e hana like me ka hoʻolālā ARM me 64 MB o RAM a ma ka hale hoʻolālā x86_64 me 32 GB o RAM. No laila, ua hoʻoholo mākou e kākau i kā mākou iho, hiki iā ia ke hana i kēia mau mea āpau. Eia ka mea i loaa ia makou:
ʻO ka hōʻuluʻulu ʻana i ka hiki ʻana o ʻekolu ala no nā topologies pūnaewele like ʻole
Ka ʻike ʻana i kekahi mau ana nui
kuhikuhipuʻuone
Hoʻohana mākou iā Golang ma ke ʻano he ʻōlelo papahana nui, ma ka hāmeʻa a ma ke kikowaena data. Ua maʻalahi loa ia i ke ola me kāna hoʻokō ʻana i ka multitasking a me ka hiki ke loaʻa i kahi faila binary i hoʻopili ʻia no kēlā me kēia lawelawe. ʻO ka hopena, mālama nui mākou i nā kumuwaiwai, nā ala a me nā kaʻa no ka lawe ʻana i ka lawelawe e hoʻopau i nā polokalamu, ka manawa hoʻomohala a me ka debugging code.
Hoʻokō ʻia ka ʻōnaehana e like me ka loina modular maʻamau a loaʻa i kekahi mau subsystems:
- Kakau inoa ana.
Hāʻawi ʻia kēlā me kēia metric e kāna iho ponoʻī a hoʻonohonoho ʻia ma nā kahawai. Ua hiki iā mākou ke hoʻokō i ka pololei synchronization a hiki i 10 nanoseconds. - Hoʻopaʻa ʻana i nā ana
Ke koho nei mākou ma waena o ke kākau ʻana i kā mākou waihona ponoʻī no ka manawa a i ʻole ka hoʻohana ʻana i kahi mea i loaʻa. Pono ka waihona no ka ʻikepili hope e pili ana i ka nānā ʻana ma hope, ʻo ia hoʻi, ʻaʻole i loaʻa ka ʻikepili no nā lohi ma ke kahawai i kēlā me kēia 0.5 milliseconds a i ʻole nā helu helu hewa i ka pūnaewele lawe, akā aia ka wikiwiki ma kēlā me kēia interface i kēlā me kēia 500 milliseconds. Ma waho aʻe o nā koi kiʻekiʻe no ka cross-platform a me ka hoʻohana haʻahaʻa haʻahaʻa, he mea koʻikoʻi loa iā mākou e hiki ke hana. ʻo ka ʻikepili kahi i mālama ʻia ai. Mālama kēia i nā kumuwaiwai helu nui. Ua hoʻohana mākou i ka Tarantool DBMS i kēia papahana mai 2016 a hiki i kēia manawa ʻaʻole mākou e ʻike i kahi pani no ia ma ka pae. Hiki ke maʻalahi, me ka hoʻohana waiwai kūpono, ʻoi aku ma mua o ke kākoʻo ʻenehana kūpono. Hoʻokomo pū ʻo Tarantool i kahi module GIS. ʻOiaʻiʻo, ʻaʻole ikaika e like me PostGIS, akā lawa ia no kā mākou mau hana o ka mālama ʻana i kekahi mau metric pili i ka wahi (pili no ka lawe ʻana). - ʻIke ʻana i nā ana
He mea maʻalahi nā mea a pau maʻaneʻi. Lawe mākou i ka ʻikepili mai ka hale kūʻai a hōʻike iā ia i ka manawa maoli a i ʻole retrospectively. - ʻO ka hoʻonohonoho ʻana o ka ʻikepili me ka ʻōnaehana nānā kikowaena.
Loaʻa i ka ʻōnaehana kiaʻi kikowaena ka ʻikepili mai nā mea hana a pau, mālama iā ia me kahi mōʻaukala kikoʻī a hoʻouna ʻia i ka ʻōnaehana nānā o ka Customer ma o API. ʻAʻole like me nā ʻōnaehana nānā maʻamau, kahi e hele ai ke "poʻo" a hōʻiliʻili i ka ʻikepili, loaʻa iā mākou ka ʻaoʻao ʻē aʻe. Hoʻouna nā mea hana i ka ʻikepili ke loaʻa kahi pilina. He wahi koʻikoʻi loa kēia, no ka mea hiki iā ʻoe ke loaʻa ka ʻikepili mai ka hāmeʻa no kēlā mau manawa i loaʻa ʻole ai a ʻaʻole hoʻouka i nā kahawai a me nā kumuwaiwai ʻoiai ʻaʻole i loaʻa ka hāmeʻa. Hoʻohana mākou i ke kikowaena nānā Influx ma ke ʻano he ʻōnaehana nānā kikowaena. ʻAʻole like me kona mau analogues, hiki iā ia ke hoʻokomo i ka ʻikepili retrospective (ʻo ia hoʻi, me kahi hōʻailona manawa ʻokoʻa mai ka manawa i loaʻa ai nā metric) ʻIke ʻia nā metric i hōʻiliʻili ʻia e Grafana, hoʻololi ʻia me kahi faila. Ua koho ʻia kēia pūʻulu maʻamau no ka mea ua mākaukau ʻia nā hoʻohui API me kahi ʻōnaehana nānā mea kūʻai aku. - Hoʻonohonoho ʻikepili me kahi ʻōnaehana hoʻokele kikowaena.
Hoʻohana ka ʻōnaehana hoʻokele polokalamu iā Zero Touch Provisioning (hōʻano hou i ka firmware, hoʻonohonoho, a me nā mea ʻē aʻe) a, ʻaʻole like me ka ʻōnaehana nānā, loaʻa wale nā pilikia ma kēlā me kēia mea. ʻO kēia nā mea hoʻomaka no ka hana ʻana o nā lawelawe kiaʻi lako lako a me nā metric āpau o nā ʻōnaehana kākoʻo ola: CPU a me SSD wela, CPU haʻahaʻa, wahi manuahi a me ke olakino SMART ma nā disks. Kūkulu ʻia ka waihona subsystem ma Tarantool. Hāʻawi kēia iā mākou i ka wikiwiki nui i ka hōʻuluʻulu ʻana i nā kaʻina manawa ma waena o nā tausani o nā mea hana, a hoʻopau pū i ka pilikia o ka hoʻonohonoho ʻana i ka ʻikepili me kēia mau mea hana. Loaʻa iā Tarantool kahi ʻōnaehana hoʻouna maikaʻi loa a hōʻoia ʻia. Loaʻa iā mākou kēia hiʻohiʻona koʻikoʻi mai ka pahu, maikaʻi!
Pūnaehana hoʻokele pūnaewele
He aha ka mea aʻe
I kēia manawa, ʻo kā mākou loulou nāwaliwali loa ka ʻōnaehana nānā kikowaena. Hoʻokō ʻia ʻo 99.9% ma kahi waihona maʻamau a he nui nā hemahema:
- Nalo ka InfluxDB i ka ʻikepili ke nalowale ka mana. Ma keʻano he kānāwai, ʻohi koke ka mea kūʻai aku i nā mea a pau e hele mai ana mai nā mea hana a ʻaʻole i loaʻa i ka waihona ʻikepili i ʻoi aku ma mua o 5 mau minuke, akā i ka wā e hiki mai ana e lilo kēia i mea ʻeha.
- He nui nā pilikia o Grafana me ka hōʻuluʻulu ʻikepili a me ka hoʻonohonoho ʻana o kāna hōʻike. ʻO ka pilikia maʻamau ka loaʻa ʻana o ka ʻikepili i kahi kaʻina manawa me ka wā o 2 kekona e hoʻomaka ana mai, e ʻōlelo, 00:00:00, a hoʻomaka ʻo Grafana e hōʻike i ka ʻikepili i ka hōʻuluʻulu mai +1 kekona. ʻO ka hopena, ʻike ka mea hoʻohana i ka pakuhi hula.
- ʻO ka nui o nā code no ka hoʻohui ʻana i ka API me nā ʻōnaehana nānā ʻaoʻao ʻekolu. Hiki ke hana hou ʻia a kākau hou ʻia ma Go)
Manaʻo wau ua ʻike pono ʻoe i ke ʻano o Grafana a ʻike i kona mau pilikia me ka ʻole oʻu, no laila ʻaʻole wau e hoʻonui i ka pou me nā kiʻi.
