Method Detail

withPath

public AwsCompact.Builder withPath(String path)

The path (URI) to an existing segment store. This parameter is required.

Parameters:

path - the path to an existing segment store.

Returns:

this builder.

withForce

public AwsCompact.Builder withForce(boolean force)

Whether to fail if run on an older version of the store of force upgrading its format.

Parameters:

force - upgrade iff true

Returns:

this builder.

withSegmentCacheSize

public AwsCompact.Builder withSegmentCacheSize(int segmentCacheSize)

The size of the segment cache in MB. The default of SegmentCache.DEFAULT_SEGMENT_CACHE_MB when this method is not invoked.

Parameters:

segmentCacheSize - cache size in MB

Returns:

this builder

Throws:

IllegalArgumentException - if segmentCacheSize is not a positive integer.

withGCLogInterval

public AwsCompact.Builder withGCLogInterval(long gcLogInterval)

The number of nodes after which an update about the compaction process is logged. Set to a negative number to disable progress logging. If not specified, it defaults to 150,000 nodes.

Parameters:

gcLogInterval - The log interval.

Returns:

this builder.

withGCType

public AwsCompact.Builder withGCType(SegmentGCOptions.GCType gcType)

The garbage collection type used. If not specified it defaults to full compaction

Parameters:

gcType - the GC type

Returns:

this builder

withCompactorType

public AwsCompact.Builder withCompactorType(SegmentGCOptions.CompactorType compactorType)

The compactor type to be used by compaction. If not specified it defaults to "parallel" compactor

Parameters:

compactorType - the compactor type

Returns:

this builder

withConcurrency

public AwsCompact.Builder withConcurrency(int concurrency)

The number of threads to be used for compaction. This only applies to the "parallel" compactor

Parameters:

concurrency - the number of threads

Returns:

this builder

build

public AwsCompact build()

Create an executable version of the Compact command.

Returns:

an instance of Runnable.
