Case Study: Twoo.com achieves 30 million users and 4.4 billion daily transactions with Clustrix

Over 30 million users in 3 years with ClustrixDB

Twoo.com is a rapidly growing social discovery site (30 million users in three years, ~11 million monthly uniques and ~3 million daily actives) that faced massive scale, performance and consistency challenges. The service needed sub-40ms database access for pages, supported multi‑billion‑row tables and complex 5–7 table joins, produced petabytes of read/write traffic per month, and wanted to avoid the operational overhead and query limitations of sharded MySQL or NoSQL approaches—all without hiring a full‑time DBA team.

Twoo solved this by running its entire production on a single scale‑out ClustrixDB cluster (21‑node master + 21‑node DR, 336 cores total), which delivered ACID SQL, sub‑5ms average queries, online schema changes on multi‑terabyte tables, and seamless linear scaling simply by adding nodes. The result was fast time‑to‑market (site launched in under six months), elimination of prior scaling pain, five‑9s availability, and the ability to support 4.4 billion transactions per day and continuing rapid user growth without a dedicated DBA staff.
