I used the following code to delete documents from RavenDB. At the bottom of Raven UI, I can see the number of documents decrease from 3,000,000 to 2,000,000. But the size of the "Data" file does not shrink down. It is always about 100G.

            store.DatabaseCommands.DeleteByIndex("Sagas/ByStarted", new IndexQuery
            {
                Query = "Started:{00010101000000 TO 20130101000000}",
            });

推荐答案

这是设计使然.默认情况下，我们不会将空间返还给操作系统.我们保留并根据需要再次使用该空间.如果您确实需要修剪文件大小，则需要压缩数据库，但这是离线操作.

That is by design. We don't give out space back to the OS by default. We keep and reuse that space again as needed. If you really need to trim the file size, you would need to compact the db, but that is an offline operation.
