Create a policy to reorder chunks on a given hypertable index in the
background. (See reorder_chunk). Only one reorder policy may
exist per hypertable. Only chunks that are the 3rd from the most recent will be
reordered to avoid reordering chunks that are still being inserted into.
Once a chunk has been reordered by the background worker it will not be reordered again. So if one were to insert significant amounts of data in to older chunks that have already been reordered, it might be necessary to manually re-run the reorder_chunk_ function on older chunks, or to drop and re-create the policy if many older chunks have been affected.
Hypertable to create the policy for.
Existing index by which to order rows on disk.
Set to true to avoid throwing an error if the reorder_policy already exists. A notice is issued instead. Defaults to false.
