What's new in Apache Accumulo 1.4.0:

February 2nd, 2013

Major features added prior to Incubation:
· Tablet merging
· Efficient deletion of row range
· Compaction of row range
· Table cloning
· FATE : Fault Tolerant Executor. Used to make table operation survive master restart.
· Concurrent table operation execute correctly
· Bulk load is now done by master and tablet servers and uses FATE to survive server restarts.
· Multi-level RFile index
· Merging minor compactions
· Logical time for bulk import

Minor features added prior to Incubation:
· Monitor will display tablet server and loggers that have died
· Shell and CloudbaseInputFormat will test extension classes before using them
· Empty tablet directories will be removed
· ZooKeeper ACLs prevent accidental disclosure of user passwords
· Compact and flush can wait for completion
· Additional test to verify master persistent state and concurrent table operations
· Added security checks to limit runtime environment of pluggable components
· Made monitor page display cache info
· Made file limit configuration less confusing
· Easily iterate over rows with new row iterator that wraps a scanner
· New row input format for mapre reduce jobs
· Execute iterators in a client client side iterator
· Introduced file archive example
· Added getMaxRow table operation
· Replaced Aggregators with Combiners which are iterators
· Made Filters Iterators
· New API for configuring iterators
· Added visibility constraint, it prevents users from writing data they can not read
· Removed dependency on accumulo-site.xml from client library.
· Improved tracing granularty
· Added information about running scans to monitor page

Preformance improvements added prior to incubation:
· Cache no longer accesses Namenode when data is in cache. Now all file names generated by Accumulo are unique over time.
· No longer use file flage in HDFS, reducing pressure on Namenode.
· Shorter tablet dir names, saves namenode memory.
