An aggregate iterator view of the one or more source
A fused view providing read-write operations on multiple B+-Trees mapping variable length unsigned byte keys to arbitrary values.
This package provides support for a view of a local B+-Tree comprised
of one or more source B+-Tree instances. The first component of the view is
always a mutable
BTree used to absorb writes for the
view (read-only views use a read-only instance of that BTree). The sources in
the view are ordered. Reads read against the sources in order, stopping on the
first source for which their is a hit for a tuple. Writes are always directed
to the first source in the view.
Fused views are the basic building block for index partitions. Each index
partition consists of a mutable B+-Tree on the live journal and zero or more
IndexSegments having historical data for the same
