Method Detail

canonicalizeQueryArgumentScalar

Comparable canonicalizeQueryArgumentScalar(Comparable value)

Canonicalizes the given value for the purpose of a hash-based lookup.

The method is used while performing InPredicate queries to canonicalize the set of values in question, so additional duplicate-eliminating post-processing step can be avoided.

Parameters:

value - the value to canonicalize.

Returns:

the canonicalized value.

hasPartitionIndexed

boolean hasPartitionIndexed(int partitionId)

Returns true if the given partition is indexed by this index, false otherwise.

markPartitionAsIndexed

void markPartitionAsIndexed(int partitionId)

Marks the given partition as indexed by this index.

Parameters:

partitionId - the ID of the partition to mark as indexed.

markPartitionAsUnindexed

void markPartitionAsUnindexed(int partitionId)

Marks the given partition as unindexed by this index.

Parameters:

partitionId - the ID of the partition to mark as unindexed.

getPerIndexStats

PerIndexStats getPerIndexStats()

Returns the index stats associated with this index.
