Subject: [PATCH] Sanitise RegionFileCache and make configurable.
|
|
|
|
RegionFileCache prior to this patch would close every single open region
|
|
file upon reaching a size of 256.
|
|
This patch modifies that behaviour so it closes the the least recently
|
|
used RegionFile.
|
|
The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap).
|
|
The maximum size of the RegionFileCache is also made configurable.
