Milvus 2.0 - A Glimpse at New Features

What this post added

This post introduces entity deletion in Milvus 2.0, explaining its asynchronous and logical nature. It details how deleted entities are marked and become invisible based on the consistency level. The post also elaborates on the four consistency levels (STRONG, EVENTUALLY, BOUNDED, SESSION) and demonstrates the performance difference between STRONG and BOUNDED consistency through latency measurements. Additionally, it introduces the 'handoff' feature, which automatically loads indexed segments to replace streaming data, enhancing search performance.
