Storage Files and Directories

This is the manual for older MicroStream versions (Version < 5.0).

The new documentation (Version >= 5.0) is located at:

https://docs.microstream.one/

Using a Storage Live File Provider (one.microstream.storage.types.StorageLiveFileProvider) allows to specify the location and naming rules for all storage related files.

available properties are:

BaseDirectory The Microstream storages location base directory. Contains channel directories and type dictionary file.
DeletionDirectory If configured, the storage will not delete files. Instead of deleting a file it will be moved to this directory.
TruncationDirectory If configured, files that will get truncated are copied into this directory.
