Derek Collison	a778921b8c	Fixed a bug that when sequences were deleted and we cleaned up empty nodes we would not redo heights and balances. ... This caused a rotate operation to possibly return nil and replace our root with nil when non empty. Signed-off-by: Derek Collison <derek@nats.io>	2023-07-30 11:01:32 -07:00
Derek Collison	4d7cd26956	Add in support for segmented binary stream snapshots. ... Streams with many interior deletes was causing issues due to the fact that the interior deletes were represented as a sorted []uint64. This approach introduces 3 sub types of delete blocks, avl bitmask tree, a run length encoding, and the legacy format above. We also take into account large interior deletes such that on receiving a snapshot we can skip things we already know about. Signed-off-by: Derek Collison <derek@nats.io>	2023-07-03 08:41:33 -07:00
Derek Collison	a744e1d5c9	Added ability to set initial minimum value for seqset when known. ... We know the minimum value when creating a new filestore msgBlk. Signed-off-by: Derek Collison <derek@nats.io>	2023-04-18 22:23:11 -07:00
