"For a typical 1-KB item, Cosmos DB guarantees end-to-end latency of reads under 10 ms and indexed writes under 15 ms at the 99th percentile, within the same Azure region."
i.e. 1 KB item; Same Azure region;
This now seems more plausible.
One thing I'm curious about is if they tested load on a single partition, or if they only tested latencies for random access.
- aravindkr1 9y agoCosmos DB guarantees both low latency and that you can achieve your provisioned throughput with SLAs. Latency is guaranteed at p99 regardless of storage size or number of partitions.
- yazaddaruvala 9y agoSorry, I'm not talking about "number of partitions" but if I "forcibly"[0] hit the same partition, will the SLA hold? [0] i.e. If I somehow pick keys which are on the same partition.
- ChuckMcM 9y agoIt is interesting that given their scale it essentially says that you can implement twitter on one of these and be done with a chunk of the infrastructure.
