Hi Luis,
You can try by setting it to false. The choice may depend on which type of
mosaic you are configuring.
Let me provide some additional details.
When it is set to false, the imageMosaic invokes an
ImageReader.read(imageIndex, ImageReadParam) operations which use the
Immediate Model and load the requested part of the image in memory (in
compliance with imageIndex and imageReadParam). After this, it disposes the
reader and closes the stream.
When it is set to true, the imageMosaic uses JAI ImageRead operations which
is based on the Deferred Execution Model. The Deferred Execution Model
leverages on TileCaches and TileSchedulers to load Tiles (composing the
requested image) in memory only when they are really needed (as an instance
on rendering request). The reader is not explicitly closed.
Hope this helps.
