Log Structured Storage

Changes are buffered in memory, and once enough changes have accumulated

Changes are buffered in memory, and once enough changes have accumulated,
they are written in one continuous disk write operation.
(According to a test, write throughput of a common SSD gets higher the larger the block size,
until a block size of 2 MB, and then does not further increase.)
But of course, if needed, changes can also be persisted if only little data was changed.
The estimated amount of unsaved changes is tracked.
The plan is to automatically store in a background thread once there are enough changes.
By default, committed changes are automatically written once every second
in a background thread, even if only little data was changed.
Changes can also be written explicitly by calling
<code>
store()

To avoid out of memory, uncommitted changes are also written when needed,
however they are rolled back when closing the store,
or at the latest (when the store was not correctly closed) when opening the store.
