Method Detail

getAggregationBlockColumn

public String getAggregationBlockColumn(String schemaName,
                                        String tableName)

Returns the column name used for indicating aggregation block. Typically, the underlying database is physically partitioned on this column to speed up accessing particular blocks.

Parameters:

schemaName -

tableName -

Returns:

getMetaForTable

public ScrambleMeta getMetaForTable(String schemaName,
                                    String tableName)

getAggregationBlockCount

public int getAggregationBlockCount(String schemaName,
                                    String tableName)

Returns the number of the blocks for a specified scrambled table.

Parameters:

schemaName -

tableName -

Returns:

getSubsampleColumn

@Deprecated
public String getSubsampleColumn(String aliasName)

Deprecated.

getSubsampleColumn

public String getSubsampleColumn(String schemaName,
                                 String tableName)

getTierColumn

@Deprecated
public String getTierColumn(String aliasName)

Deprecated.

getTierColumn

public String getTierColumn(String schemaName,
                            String tableName)

addScrambleMeta

public void addScrambleMeta(ScrambleMeta tablemeta)

Add a new scramble meta entry. If there exists an existing entry for the same scrambled table, the value is overwritten.

Parameters:

tablemeta -

insertScrambleMetaEntry

@Deprecated
public void insertScrambleMetaEntry(String aliasName,
                                                String subsampleColumn,
