Method Details

of

static FixedPartitionedEnterpriseTableLocationKey of(@NotNull
 @NotNull String columnPartitionKey,
 @NotNull
 io.deephaven.shadow.enterprise.com.illumon.iris.db.v2.locations.TableLocationKey enterpriseKey)

Create a TableLocationKey from its enterprise equivalent and the partitioning column key.

Parameters:

columnPartitionKey - the partitioning column name

enterpriseKey - the source enterprise key

Returns:

a new FixedPartitionedEnterpriseTableLocationKey

makePartitionMap

@Nullable
static @Nullable Map<String,Comparable<?>> makePartitionMap(@NotNull
 @NotNull String columnPartitionKey,
 @NotNull
 io.deephaven.shadow.enterprise.com.illumon.iris.db.v2.locations.TableLocationKey enterprise)

Convert the enterprise TableLocationKey into a Community partition map. Note that if the columnPartitionKey is UNPARTITIONED_KEY_PLACEHOLDER this will return null to indicate the location is not partitioned.

Parameters:

columnPartitionKey - The key for the column partition

enterprise - the enterprise table location key

Returns:

a map of partitions, or null if the columnPartitionKey is UNPARTITIONED_KEY_PLACEHOLDER

adapt

Return an Enterprise TableLocationKey version of this key.

Returns:

an Enterprise TableLocationKey

tryAdapt

@Nullable
static io.deephaven.shadow.enterprise.com.illumon.iris.db.v2.locations.TableLocationKey tryAdapt(TableLocationKey actualKey)
