Method Details

getPartitions

@NotNull
@NotNull Map<String,Comparable<?>> getPartitions()

Get the Column and Internal partitions as a map.

Returns:

a map of the partitions

hasLocationSnapshot

default boolean hasLocationSnapshot()

Check if this table has a metadata index

Returns:

true if it does.

partitionOnlyHashCode

static int partitionOnlyHashCode(@NotNull
 @NotNull EnterpriseTableLocationKey key)

Compute the hash code of the key using only the partitions.

Parameters:

key - the key to compute the hash code for

Returns:

the computed hash code

partitionOnlyCompare

static int partitionOnlyCompare(@NotNull
 @NotNull EnterpriseTableLocationKey left,
 @Nullable
 @Nullable TableLocationKey right)

Compare two location keys, automatically mapping the column and internal partition values.

Parameters:

left - the lhs of the comparison

right - the rhs of the comparison

Returns:

the comparison result following the conventions of Comparable.compareTo(Object)

partitionOnlyEquals

static boolean partitionOnlyEquals(@NotNull
 @NotNull EnterpriseTableLocationKey left,
 @Nullable
 @Nullable Object right)

Check for equality between two location keys using only the partition values.

Parameters:

left - the lhs of the equality

right - the rhs of the equality

Returns:

if the partitions are equal
