changes to add sharp checkpoint

Fixed a bug in the lsm-btree range search cursor where "proceed" is called unnecessarily twice for the first tuple that satisfy the search predicate. Modified the existing search call back test case to cover the fix of locking anti-matter tuples.

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2948 123451ca-8445-de46-9d55-352943316053

Fixed the issue of not locking in-memory anti-mattered tuples in the LSM_BTree range cursor which may result in reading un-committed data.

All lsm indexes (BTree, RTree, and inverted index) are now using bloom filters whenever possible.

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree_bloom_filter@2776 123451ca-8445-de46-9d55-352943316053

fixed bug that caused merge operations not to cleanup merged components

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2707 123451ca-8445-de46-9d55-352943316053

Integrated bloom filters with LSM-BTree during flushes, merges, and bulkload. All tests pass except the merge test due to what it seems a bug in the cleanup after merges if there are no search threads accessing the disk components. Next is to use bloom filters during search and also with other lsm indexes.

getWrite/ReadDevices returns Set instead of List; RTree IO operations now also returns buddy btree devices; hid merge/flush behind internal interface;

Allowing LSM file managers to be initialized with a starting IO device index. Using that mechanism, the first disk component of the i-th partition of an Asterix LSM index is written on the i-th IO device (further components are assigned to IO devices in a round robin fashion).

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2585 123451ca-8445-de46-9d55-352943316053

* The cleanup of the merged components in the LSM indexes is now the responsibility of either: the last existing search thread (in case the merge process is over and there are still search threads accessing the merged components), or the merge thread itself (in case the merge process is over and there are no search threads accessing the merged components). * Allowed concurrent merges to occur at the same time instead of the old design which only allowed one merge process at a time per LSM index.

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2573 123451ca-8445-de46-9d55-352943316053

Restored interface that was mitakenly deleted in r2552.

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2561 123451ca-8445-de46-9d55-352943316053

Removed two unnecessary methods from the file manager interface.

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2553 123451ca-8445-de46-9d55-352943316053

Refactored the LSM-indexes to use common abstract class. Added new ILSMComponent interface to represents the LSMComponents instead of passing Objects all around the place. Removed the component finalizers classes and cleaned the file manager API. Fixed couple of bugs. Cleaned the code and changed the names of many methods.

  1. … 35 more files in changeset.
Fixed a bug introduced in r2413 that leadto LSM searches being executed as 'try' operations. This caused searchers not to wait for flushes, which violates our current CC protocol, and ultimately lead to hanging threads.

git-svn-id: https://hyracks.googlecode.com/svn/branches/hyracks_lsm_tree@2483 123451ca-8445-de46-9d55-352943316053
