Zilliz Global Cluster Q&A : Cross-Region Write Latency Explained

In our previous videos, we introduced 𝗭𝗶𝗹𝗹𝗶𝘇 𝗚𝗹𝗼𝗯𝗮𝗹 𝗖𝗹𝘂𝘀𝘁𝗲𝗿: one primary cluster and multiple read-only secondary clusters across regions to support resilient vector search, low-latency local reads, and regional failover. Let’s use a more specific example to explain: 𝗪𝗵𝗮𝘁 𝗵𝗮𝗽𝗽𝗲𝗻𝘀 𝘄𝗵𝗲𝗻 𝗮 𝘂𝘀𝗲𝗿 𝗶𝗻 𝗔𝗣𝗔𝗖 𝘄𝗿𝗶𝘁𝗲𝘀 𝗱𝗮𝘁𝗮 𝘁𝗼 𝗮 𝗽𝗿𝗶𝗺𝗮𝗿𝘆 𝗰𝗹𝘂𝘀𝘁𝗲𝗿 𝗶𝗻 𝘁𝗵𝗲 𝗨𝗦, 𝘁𝗵𝗲𝗻 𝗻𝗲𝗲𝗱𝘀 𝘁𝗼 𝗿𝗲𝗮𝗱 𝘁𝗵𝗮𝘁 𝗱𝗮𝘁𝗮 𝗹𝗼𝗰𝗮𝗹𝗹𝘆? In this clip, @Jiangchen breaks the latency path into four parts: • The write request first travels from APAC to the primary cluster in the US. • The data change is then replicated from the primary to a secondary cluster in APAC. • Once the local secondary has the update, read traffic can be served locally with low latency. • The exact latency depends on the cloud provider’s cross-region network. ▶ Full Zilliz Global Cluster webinar replay: https://youtu.be/9n1I-Varui8
