[ASTERIXDB-2286][COMP][FUN][HYR] Parallel Sort Optimization

- user model changes: yes

- storage format changes: no

- interface changes: yes

details:

- new plan for sort operation which includes sampling and

replicating the stream of data to be sorted. Sort-merge connector

is removed from the plan. The sorted result now is in multiple partitions.

- new optimization rule to check whether full parallel sort is applicable.

- new Forward operator to read the replicated sort input stream and

to receive the ouput of the sampling.

- new sequential merge connector to merge a globally ordered result residing

in multiple partitions (in addition to the connector's partition computer).

- "asterix-lang-aql/pom.xml" is changed as a result of refactoring

code related to the range map handling.

- new private sampling function to generate the range map object

(local & global functions) & their type computers.

user model changes:

- new compiler property is added to enable and disable parallel sort.

interface changes:

- "ILogicalOperatorVisitor.java" includes Forward Operator.

- "ITuplePartitionComputer.java" includes initialize() to enable partitioner

to do some initialization. FieldRangePartitionComputerFactory uses it to

pick a range map.

- "ITuplePartitionComputerFactory.java". createPartitioner() is changed to

createPartitioner(IHyracksTaskContext hyracksTaskContext). Context is needed

for transferring the range map throught the context.

[ASTERIXDB-1130][STO]: JSON serialization for persisted objects

- user model changes: no

- storage format changes:

This change replaces the use of Java serialization for persisted objects

such as dataset/index metadata, checkpoints, ect...

This will break backward compatibly with any existing AsterixDB instance.

However, the change is needed to enable future backward compatibility support

for persisted objects.

- interface changes:

IJsonSerializable: contains API to serialize a class as a JsonNode.

IPersistedResourceRegistry: contains a mapping between an IJsonSerializable

class and a unique type id. An IPersistedResourceRegistry is responsible

for generating the class identifier in the JSON output.

The class identifier will always contain the following attributes:

@type: a unique type id that identifies the object type.

@version: the version of the serialized class.

@class: the serialized class full name.

Any registered class with PersistedResourceRegistry must provide

a static fromJson(IPersistedResourceRegistry, JsonNode) method for

deserialization. This is ensured during the class registration process.

[ASTERIXDB-2339] Add a new inverted index merge cursor

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

- Implement a new inverted index merge cursor which uses two priority queues,

one for tokens and one for keys. For each token, we merge their inverted

lists using the key queue. After that, we fetch the next token and merge

their lists again. This reduces unnecessary token comparision a lot.

- Along this change, created a fast path for inverted index bulkloader.

Based on how the token+key pair is created, there is no need to copy

bulkloaded tuple and check whether it's a new token during merge.

[ASTERIXDB-2149] Enable multiple normalized keys in sort

- user model changes: no

- storage format changes: no

- interface changes: yes. The interface of sort is changed.

Currently, during the (in-memory) sort, we use an int normalized keys to

speed up comparisions by avoiding random memory accesses. However, this

technique is inefficient if the first 4 bytes of the sorting keys are

not distinctive. From performance point of view, it's better to use

longer normalized keys when it's possible (2-3x improvements).

This is enabled by this patch by:

- Allowing multiple normalized keys during sort, and the length of each

normalized key can be longer (multiple integers).

- Enable memory budgeting of pointer directories as well during sort

(but for performance, we still use int[], instead of byte[] from frame).

The next patch will enable the AsterixDB layer to use this feature to

speed up sort performance.

- For Optimzed Hybrid Hash Join, we calculate the expected hash table size when the build phase is done and

try to spill one or more partitions if the freespace can't afford the hash table size.

- For External Hash Group By, the number of hash entries (hash table size) is calculated based on

an estimation of the aggregated tuple size and possible hash values for the given field size in that tuple.

- Garbage Collection feature has been added to SerializableHashTable. For external hash group-by,

whenever we spill a data partition to the disk, we also check the ratio of garbage in the hash table.

If it's greater than the given threshold, we conduct a GC on Hash Table.
