All Implemented Interfaces:

HeapSize

Enclosing class:

WALSplitter
```
public static class WALSplitter.RegionEntryBuffer
extends Object
implements HeapSize
```
A buffer of some number of edits for a given region. This accumulates edits and also provides a memory optimization in order to share a single byte array instance for the table and region name. Also tracks memory usage of the accumulated edits.
