Method Detail

bucketHigh

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions bucketHigh(Double bucketHigh)

Size-tiered compaction strategy (STCS) is used in the newest window, this method sets the bucketHigh value used in STCS.

If no call is made to this method, the default value set by Cassandra is 1.5.

Parameters:

bucketHigh - the new value.

Returns:

this object (for call chaining).

bucketLow

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions bucketLow(Double bucketLow)

Size-tiered compaction strategy (STCS) is used in the newest window, this method sets the bucketLow value used in STCS.

If no call is made to this method, the default value set by Cassandra is 0.5.

Parameters:

bucketLow - the new value.

Returns:

this object (for call chaining).

compactionWindowUnit

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions compactionWindowUnit(TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.CompactionWindowUnit compactionWindowUnit)

Sets the time unit used to define the window size

If no call is made to this method, the default value set by Cassandra is DAYS.

Parameters:

compactionWindowUnit - TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.CompactionWindowUnit.MINUTES, TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.CompactionWindowUnit.HOURS or TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.CompactionWindowUnit.DAYS.

Returns:

this object (for call chaining).

compactionWindowSize

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions compactionWindowSize(Integer compactionWindowSize)

Sets the number of units that make up a window.

If no call is made to this method, the default value set by Cassandra is 1.

Parameters:

compactionWindowSize - the size of the first window.

Returns:

this object (for call chaining).

minThreshold

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions minThreshold(Integer minThreshold)

Sets the minimum number of SSTables to trigger a minor compaction

If no call is made to this method, the default value set by Cassandra is 4.

Parameters:

minThreshold - the new value.

Returns:

this object (for call chaining).

maxThreshold

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions maxThreshold(Integer maxThreshold)

Sets the maximum number of SSTables to allow in a minor compaction.

If no call is made to this method, the default value set by Cassandra is 32.

Parameters:

maxThreshold - the new value.

Returns:

this object (for call chaining).

minSSTableSizeInBytes

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions minSSTableSizeInBytes(Long minSSTableSize)

Size-tiered compaction strategy (STCS) is used in the newest window, this method sets the minSSTableSize value used in STCS.

If no call is made to this method, the default value set by Cassandra is 52428800 (50 MB).

Parameters:

minSSTableSize - the new value.

Returns:

this object (for call chaining).

timestampResolution

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions timestampResolution(TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.TimeStampResolution timestampResolution)

Sets the timestamp resolution, depending on the timestamp unit of the data you insert.

If no call is made to this method, the default value set by Cassandra is MICROSECONDS.

Parameters:

timestampResolution - TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.TimeStampResolution.MICROSECONDS or TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions.TimeStampResolution.MILLISECONDS.

Returns:

this object (for call chaining).

unsafeAggressiveSSTableExpiration

public TableOptions.CompactionOptions.TimeWindowCompactionStrategyOptions unsafeAggressiveSSTableExpiration(Boolean unsafeAggressiveSSTableExpiration)

Allow expired sstables to be dropped without checking if its data is shadowing other sstables. This is a potentially risky option that can lead to data loss or deleted data re-appearing.

If no call is made to this method, the default value set by Cassandra is false.

Parameters:

unsafeAggressiveSSTableExpiration - whether to enable unsafe aggressive sstable expiration option.

Returns:

this object (for call chaining).
