Constructor Detail

• CreateTableOptions

  public CreateTableOptions()

Method Detail

• addSplitRow

  public CreateTableOptions addSplitRow(PartialRow row)

  Add a split point for the table. The table in the end will have splits + 1 tablets. The row may be reused or modified safely after this call without changing the split point.

  Parameters:

  row - a key row for the split point

  Returns:

  this instance

• addHashPartitions

  public CreateTableOptions addHashPartitions(List<String> columns,
                                     int buckets)

  Add a set of hash partitions to the table. Each column must be a part of the table's primary key, and an individual column may only appear in a single hash component. For each set of hash partitions added to the table, the total number of table partitions is multiplied by the number of buckets. For example, if a table is created with 3 split rows, and two hash partitions with 4 and 5 buckets respectively, the total number of table partitions will be 80 (4 range partitions * 4 hash buckets * 5 hash buckets).

  Parameters:

  columns - the columns to hash

  buckets - the number of buckets to hash into

  Returns:

  this instance

• addHashPartitions

  public CreateTableOptions addHashPartitions(List<String> columns,
                                     int buckets,
                                     int seed)

  Add a set of hash partitions to the table. This constructor takes a seed value, which can be used to randomize the mapping of rows to hash buckets. Setting the seed may provide some amount of protection against denial of service attacks when the hashed columns contain user provided values.

  Parameters:

  columns - the columns to hash

  buckets - the number of buckets to hash into

  seed - a hash seed

  Returns:

  this instance

• setRangePartitionColumns

  public CreateTableOptions setRangePartitionColumns(List<String> columns)

  Set the columns on which the table will be range-partitioned. Every column must be a part of the table's primary key. If not set, the table will be created with the primary-key columns as the range-partition columns. If called with an empty vector, the table will be created without range partitioning.

  Parameters:

  columns - the range partitioned columns

  Returns:

  this instance

• setNumReplicas

  public CreateTableOptions setNumReplicas(int numReplicas)

  Sets the number of replicas that each tablet will have. If not specified, it uses the server-side default which is usually 3 unless changed by an administrator.

  Parameters:

  numReplicas - the number of replicas to use

  Returns:

  this instance
