Redis yoki Apache Cassandra?

Faqat primary key indexlangan xolatda load test natijalari. 2mlnta yozish operatsiyasi, 50%i yaratish qolgani yangilash. Ikkalasi ham cluster yoki replication qilinmagan.

- Umumiy sarflangan vaqt:
Cassandra: 47.5s
Redis: 14.8s

- CPU sarfi:
Cassandra: 57-240% orasida o'ynab turdi.
Redis: 44-56% orasida o'ynab turdi.

- RAM sarfi:
Cassandra: ~5GiB
Redis: ~424MiB

Xo'sh, Redis shunchalik zo'r ekan nega Cassandra hali ham turibdi?
- Ikkalasining ham ustunlik jihatlari bor. O'zim bilgancha qaysi birini qachon ishlatishni tushuntirib ketaman.
- Redis'da limit bor, yani CPU'ni 100%'dan oshirib yubora olmaydi, sababi u bitta threadda ishlaydi.

1. Agar loyihangiz startup bo'lsa yoki tushadigan bosim redisni cheklovidan oshib ketmaydigan darajada bo'lsa redis qo'llanganingiz yaxshi
2. Agar ma'lumotlar juda ko'p va katta hajmda bo'lsa yani sharding va replication kerak deb hisoblasangiz cassandra yaxshiroq.

Cassandrani load test qilgan code: https://github.com/golanguzb70/cassandra-load-test
Redisni videoda load test qilgan edik shuni codebasini sal o'zgaritirib ishlatdim: https://youtu.be/WbleQvvCUgY?si=PUBYv1kpmwPityPV

Choose quality over quantity. Remember that one high-quality post is better than five short publications of questionable value. The group also hosted discussions on committing arson, Judge Hui said, including setting roadblocks on fire, hurling petrol bombs at police stations and teaching people to make such weapons. The conversation linked to arson went on for two to three months, Hui said. Matt Hussey, editorial director of NEAR Protocol (and former editor-in-chief of Decrypt) responded to the news of the Telegram group with “#meIRL.” Private channels are only accessible to subscribers and don’t appear in public searches.
