addRangePartition

public AlterTableOptions addRangePartition(PartialRow lowerBound,
                                           PartialRow upperBound)

Add a range partition to the table with an inclusive lower bound and an exclusive upper bound. If either row is empty, then that end of the range will be unbounded. If a range column is missing a value, the logical minimum value for that column type will be used as the default. Multiple range partitions may be added as part of a single alter table transaction by calling this method multiple times. Added range partitions must not overlap with each other or any existing range partitions (unless the existing range partitions are dropped as part of the alter transaction first). The lower bound must be less than the upper bound. This client will immediately be able to write and scan the new tablets when the alter table operation returns success, however other existing clients may have to wait for a timeout period to elapse before the tablets become visible. This period is configured by the master's 'table_locations_ttl_ms' flag, and defaults to 5 minutes.

Parameters:

lowerBound - inclusive lower bound, may be empty but not null

upperBound - exclusive upper bound, may be empty but not null

Returns:

this instance

addRangePartition

public AlterTableOptions addRangePartition(PartialRow lowerBound,
                                           PartialRow upperBound,
                                           RangePartitionBound lowerBoundType,
                                           RangePartitionBound upperBoundType)

Add a range partition to the table with a lower bound and upper bound. If either row is empty, then that end of the range will be unbounded. If a range column is missing a value, the logical minimum value for that column type will be used as the default. Multiple range partitions may be added as part of a single alter table transaction by calling this method multiple times. Added range partitions must not overlap with each other or any existing range partitions (unless the existing range partitions are dropped as part of the alter transaction first). The lower bound must be less than the upper bound. This client will immediately be able to write and scan the new tablets when the alter table operation returns success, however other existing clients may have to wait for a timeout period to elapse before the tablets become visible. This period is configured by the master's 'table_locations_ttl_ms' flag, and defaults to 5 minutes.

Parameters:

lowerBound - lower bound, may be empty but not null

upperBound - upper bound, may be empty but not null

lowerBoundType - the type of the lower bound, either inclusive or exclusive

upperBoundType - the type of the upper bound, either inclusive or exclusive

Returns:

this instance

dropRangePartition

public AlterTableOptions dropRangePartition(PartialRow lowerBound,
                                            PartialRow upperBound)

Drop the range partition from the table with the specified inclusive lower bound and exclusive upper bound. The bounds must match exactly, and may not span multiple range partitions. If either row is empty, then that end of the range will be unbounded. If a range column is missing a value, the logical minimum value for that column type will be used as the default. Multiple range partitions may be dropped as part of a single alter table transaction by calling this method multiple times.

Parameters:

lowerBound - inclusive lower bound, can be empty but not null

upperBound - exclusive upper bound, can be empty but not null

Returns:

this instance

dropRangePartition

public AlterTableOptions dropRangePartition(PartialRow lowerBound,
                                            PartialRow upperBound,
                                            RangePartitionBound lowerBoundType,
                                            RangePartitionBound upperBoundType)

Drop the range partition from the table with the specified lower bound and upper bound. The bounds must match exactly, and may not span multiple range partitions. If either row is empty, then that end of the range will be unbounded. If a range column is missing a value, the logical minimum value for that column type will be used as the default. Multiple range partitions may be dropped as part of a single alter table transaction by calling this method multiple times.

Parameters:

lowerBound - inclusive lower bound, can be empty but not null

upperBound - exclusive upper bound, can be empty but not null

lowerBoundType - the type of the lower bound, either inclusive or exclusive

upperBoundType - the type of the upper bound, either inclusive or exclusive

Returns:

this instance

setWait

public AlterTableOptions setWait(boolean wait)

Whether to wait for the table to be fully altered before this alter operation is considered to be finished.

If false, the alter will finish quickly, but a subsequent KuduClient.openTable(String) may return a KuduTable with an out-of-date schema.

If true, the alter will take longer, but the very next schema is guaranteed to be up-to-date.

If not provided, defaults to true.

Parameters:

wait - whether to wait for the table to be fully altered

Returns:

this instance
