ʻElima mau makahiki i hala aku nei ua hoʻāʻo wau e hana me Tarantool, akā ʻaʻole ia i hana iaʻu. Akā i kēia manawa ua paʻa wau i kahi webinar kahi aʻu i kamaʻilio ai e pili ana iā Hadoop a pehea e hana ai ʻo MapReduce. Ma laila lākou i nīnau mai ai iaʻu i kahi nīnau: "No ke aha e hoʻohana ʻole ai iā Tarantool no kēia hana?"
Ma muli o ka hoihoi, ua hoʻoholo wau e hoʻi i laila, e hoʻāʻo i ka mana hou loa - a i kēia manawa makemake nui wau i ka papahana. I kēia manawa, e hōʻike wau iā ʻoe pehea e kākau ai i kahi noi maʻalahi ma Tarantool, e hoʻouka a nānā i kāna hana, a ʻike ʻoe i ka maʻalahi a me ka ʻoluʻolu o nā mea āpau.
He aha ka Tarantool
Hoʻonoho ʻo Tarantool iā ia iho me kahi waihona ultra-wikiwiki. Hiki iā ʻoe ke waiho i nā ʻikepili āu e makemake ai ma laila. Hoʻohui hou, e hoʻopili iā lākou, shard - ʻo ia hoʻi, e hoʻokaʻawale i ka nui o ka ʻikepili ma waena o nā kikowaena a hoʻohui i nā hopena mai ia mau mea - e hana i nā pilina haku-kūpono hewa.
ʻO ka lua, he kikowaena noi kēia. Hiki iā ʻoe ke kākau i kāu mau noi ma luna o ia mea, e hana me ka ʻikepili, no ka laʻana, holoi i nā moʻolelo kahiko ma ke kua e like me kekahi mau lula. Hiki iā ʻoe ke kākau pololei i kahi kikowaena Http ma Tarantula e hana me ka ʻikepili: hāʻawi i kā lākou nui, kākau i nā ʻikepili hou ma laila a hoʻemi i nā mea āpau i ka haku.
Heluhelu wau i kahi ʻatikala e pili ana i ka hana ʻana o nā kāne i ka laina memo o 300 mau laina, ʻo ia wale nō ka pohā a me ka wikiwiki - loaʻa iā lākou ka hana haʻahaʻa o 20 mau leka i kekona. Maanei hiki iā ʻoe ke huli a kākau i kahi noi nui loa, ʻaʻole ia e waiho ʻia, e like me PostgreS.
E ho'āʻo wau e wehewehe i kahi mea e like me kēia kikowaena, maʻalahi wale nō, ma kēia ʻatikala.
Kāu Mau Koho Paʻamau
No ka hoʻāʻo, ua hoʻomaka wau i ʻekolu mau mīkini virtual maʻamau - he 20 GB hard drive, Ubuntu 18.04. 2 mau CPU virtual a me 4 gigs o ka hoʻomanaʻo.
Hoʻokomo mākou iā Tarantool - holo i ka script bash a hoʻohui i kahi waihona a hana kūpono e hoʻokomo iā Tarantool. Ka loulou i ka palapala - (curl -L | VER=2.4 sudo -E bash). Loaʻa iā mākou nā kauoha e like me:
tarantoolctl - ke kauoha nui no ka mālama ʻana i nā hihia Tarantula.
/etc/tarantool - eia ka hoʻonohonoho holoʻokoʻa.
var/log/tarantool - eia nā lāʻau.
var/lib/tarantool - aia ka ʻikepili ma ʻaneʻi, a laila ua māhele ʻia i mau manawa.
Aia nā waihona instance-available a me instance-enable - aia i loko o ka mea e hoʻokuʻu ʻia - kahi faila hoʻonohonoho hoʻonohonoho me ka lua code, e wehewehe ana i nā awa e hoʻolohe ai, he aha ka hoʻomanaʻo i loaʻa iā ia, nā hoʻonohonoho ʻenekini Vinyl, code e holo ana i ka hoʻomaka ʻana. nā kikowaena, sharding, queues, holoi i nā ʻikepili kahiko, a pēlā aku.
E like me ka PostgreS. No ka laʻana, makemake ʻoe e holo i kekahi mau kope o kahi waihona e kau ana ma nā awa like ʻole. Ua ʻike ʻia ua hoʻomaka ʻia kekahi mau waihona waihona ma kahi kikowaena hoʻokahi, e kau ana ma nā awa like ʻole. Loaʻa paha iā lākou nā hoʻonohonoho ʻokoʻa - hoʻokahi kumu hoʻokō hoʻokahi loiloi, ʻo ka lua - kekahi.
Hoʻoponopono i nā mea hoʻohālike
Loaʻa iā mākou ke kauoha tarantoolctl, hiki iā ʻoe ke hoʻokele i nā manawa Tarantula. No ka laʻana, e nānā ʻo tarantoolctl check example i ka faila hoʻonohonoho a ʻōlelo - ua maikaʻi ka faila inā ʻaʻohe hewa syntax ma laila.
Hiki iā ʻoe ke ʻike i ke kūlana o ka laʻana - tarantoolctl status example. Ma ke ala like hiki iā ʻoe ke hoʻomaka, hoʻōki, hoʻomaka hou.
Ke holo nei ka laʻana, hiki iā ʻoe ke hoʻohui iā ia ma nā ala ʻelua.
1. ʻOihana hoʻokele
Ma ka maʻamau, wehe ʻo Tarantool i kahi kumu, hoʻouna ʻia ka kikokikona ASCII maʻamau i laila e hoʻokele iā Tarantool. Hoʻohui mau ʻia ka pili ʻana i ka console ma lalo o ka mea hoʻohana admin, ʻaʻohe hōʻoia, no laila ʻaʻohe pono e hoʻopuka i waho o ka console port e hoʻokele iā Tarantula.
No ka hoʻohana ʻana i kēia ʻano hana, pono ʻoe e hoʻokomo iā Tarantoolctl e hoʻokomo i ka inoa instance. E hoʻomaka ke kauoha i ka console a hoʻohui i ka mea hoʻohana admin. Mai hōʻike i ke awa console i waho - ʻoi aku ka maikaʻi o ka waiho ʻana ma ke ʻano he kumu ʻāpana. A laila ʻo ka poʻe i hiki ke kākau i ke kumu e hiki ke hoʻopili iā Tarantula.
Pono kēia ʻano no nā mea hoʻokele. No ka hana me ka ʻikepili, e hoʻohana i ke ala ʻelua - ka protocol binary.
2. Ke hoʻohana nei i kahi protocol binary e hoʻopili i kahi awa kikoʻī
Aia i loko o ka hoʻonohonoho kahi kuhikuhi hoʻolohe, e wehe ana i kahi awa no nā kamaʻilio waho. Hoʻohana ʻia kēia awa me ka protocol binary a hiki i ka hōʻoia ʻana ma laila.
No kēia pili, hoʻohana ʻia ʻo tarantoolctl connect i ka helu port. Ke hoʻohana nei, hiki iā ʻoe ke hoʻopili i nā kikowaena mamao, hoʻohana i ka hōʻoia a hāʻawi i nā kuleana komo like ʻole.
Hoʻopaʻa ʻikepili a me ka Module pahu
No ka mea ʻo Tarantool kahi waihona a me kahi kikowaena noi, loaʻa iā ia nā modula like ʻole. Makemake mākou i ka module pahu - hoʻokō ia i ka hana me ka ʻikepili. Ke kākau ʻoe i kahi mea i ka pahu, kākau ʻo Tarantool i ka ʻikepili i ka disk, mālama iā ia i ka hoʻomanaʻo, a i ʻole hana i kekahi mea ʻē aʻe me ia.
Hoʻopaʻa leo
No ka laʻana, hele mākou i loko o ka module pahu a kāhea i ka hana box.once. E koi kēia iā Tarantool e holo i kā mākou code i ka wā i hoʻomaka ai ke kikowaena. Hana mākou i kahi e mālama ʻia ai kā mākou ʻikepili.

Hoʻopili ʻia ia ma MessagePack. He ʻano ʻano ʻoluʻolu loa kēia - he binary a lawe liʻiliʻi i ka lumi - 18 bytes versus 27.
He mea maʻalahi ke hana pū me ia. Aneane i kēlā me kēia laina, hiki i kēlā me kēia moʻolelo ʻikepili ke loaʻa nā kolamu ʻokoʻa loa.
Hiki iā mākou ke nānā i nā wahi āpau me ka hoʻohana ʻana i ke kauoha Box.space. No ke koho ʻana i kahi laʻana, e kākau i ka laʻana box.space a loaʻa ka ʻike piha e pili ana.
ʻElua mau mīkini i kūkulu ʻia ʻo Tarantool: Memory a me Vinyl. Mālama ka hoʻomanaʻo i nā ʻikepili āpau i ka hoʻomanaʻo. No laila, hana maʻalahi a wikiwiki nā mea a pau. Hoʻolei ʻia ka ʻikepili i ka disk, a aia pū kekahi me kahi ʻōnaehana log kākau mua, no laila ʻaʻole e nalowale kekahi mea inā hāʻule ke kikowaena.
Mālama ʻo Vinyl i ka ʻikepili ma ka disk ma kahi ʻano i kamaʻāina iā mākou - ʻo ia hoʻi, hiki iā ʻoe ke mālama i nā ʻikepili hou aʻe ma mua o kā mākou hoʻomanaʻo, a e heluhelu ʻo Tarantula mai ka disk.
I kēia manawa e hoʻohana mākou i ka Memory.
