ASF subversion and git services commented on ASTERIXDB-1059:
------------------------------------------------------------

Commit 1a659da1f05faa630c35c10fa0f3af3c2053ed40 in incubator-asterixdb-hyracks's branch refs/heads/master from [~imaxon]
[ https://git-wip-us.apache.org/repos/asf?p=incubator-asterixdb-hyracks.git;h=1a659da ]

Make LSM bulkload append-only and write-once.

Allows for usage of LSM indexes with underlying storage that is append-only.
This also results in a small improvement for LSM component bulk load speed.

- Tree metadata (filters, etc) now lie at the back of the tree file in
  append-only mode.
-- Note that you should *not* ever give the append-only flag on bulk-load,
   if the tree is ever to be modified in place.
- Append-only operations bypass the buffer cache for writes, but utilize
  the buffer cache for memory allocation and reads.
- Addresses ASTERIXDB-1059
