It seems I can have multiple path.data on a single node, but it does not allow for storage tiering:
# Can optionally include more than one location, causing data to be striped across # the locations (a la RAID 0) on a file level, favouring locations with most free # space on creation. For example: # # path.data: /path/to/data1,/path/to/data2 ES seems to be quite close to beeing able to provide storage tiering... Maybe in 1.4? ;) On 15 juil. 2014, at 09:33, Mark Walkom <[email protected]> wrote: > You cannot have multiple data.paths on a single node/instances.
