# snapshot

`fun snapshot(writer: SnapshotWriter): Unit`

Writes out all map entries to disk. Note that this operation does not load all entries into memory, as the SnapshotWriter is using a disk-backed buffer internally, and iterating map entries results in only a fixed number of recently accessed entries to ever be kept in memory.
