- Added Tokenize Operator in addition to the bulkload operator changes that were made by Zachary Heilbron. The tokenize operator is only added to the logical plan when bulk-loading the data. - Each secondary index is now updated in the separate branch by using the replicate operator. - Sink Operator now accepts multiple inputs. - Fixed the bulk-load so that it correctly produces auto-generated PK.

Support big vertex in Pregelix. --For those vertice beyond page size, we store them on HDFS as immutable files. --Updates on those big vertice will trigger creations of new immutable files.

Several major changes in hyracks: -- reduced CC/NC communications for reporting partition request and availability; partition request/availability are only reported for the case of send-side materialized (without pipelining) policies in case of task re-attempt. -- changed buffer cache to dynamically allocate memory based on needs instead of pre-allocating -- changed each network channel to lazily allocate memory based on needs, and changed materialized connectors to lazily allocate files based on needs -- changed several major CCNCCFunctions to use non-java serde -- added a sort-based group-by operator which pushes group-by aggregations into an external sort -- make external sort a stable sort

1,3,and 4 is to reduce the job overhead.

2 is to reduce the unecessary NC resource consumptions such as memory and files.

5 and 6 are improvements to runtime operators.

One change in algebricks:

-- implemented a rule to push group-by aggregation into sort, i.e., using the sort-based gby operator

Several important changes in pregelix:

-- remove static states in vertex

-- direct check halt bit without deserialization

-- optimize the sort algorithm by packing yet-another 2-byte normalized key into the tPointers array

add support for Hadoop Counters via job.setCounterAggregatorClass

The PregelixJob.setCounterAggregatorClass sets up a (user-specified)

global aggregator and an iterationComplete hook to save Counter values.

The user-specified Counter-based aggregator (must extend

HadoopCountersAggregator) is saved to HDFS in each iteration and should

be restart/snapshot-aware.

The usage for setting up counters is to make a call to

job.setCounterAggregatorClass. After job completion, the Counters may

be retrieved from HDFS using BspUtils.getCounters(job).

Note that there is currently only one spot for iterationComplete hooks

and this behavior occupies it.

add an "iteration complete" hook for aggregation/reporting across iterations

This commit allows the user to specify a class which will be called upon

completion of each pregelix iteration. This allows us to perform a user-

specified action between iterations.

As an example, a PerIterationGlobalAggregatesHook is provided which

saves the complete set of global aggregator states from every iteration,

allowing the user to observe aggregates from all iterations.

The default hook does nothing.

The hook instance is attached directly to the PregelixJob so that it can

be retrieved by the Driver's caller.
