Enum Constant Summary

Enum Constants

Enum Constant and Description
AsynchronousOverflow Asynchronous overflow migrates data off of the old journal and onto read-optimized index segments and is responsible for running operation which split, join, or move index partitions.
IndexSegmentBuild Operation that builds an index segment.
IndexSegmentOpenClose An IndexSegment open-close event (start is open, end is close).
IndexSegmentStoreOpenClose An IndexSegmentStore open-close event (start is open, end is close).
PurgeResources Purge resources.
SynchronousOverflow Synchronous overflow is a fast operation that occurs when the live journal is nearly at its maximum capacity.

Enum Constant Detail

SynchronousOverflow

public static final EventType SynchronousOverflow

Synchronous overflow is a fast operation that occurs when the live journal is nearly at its maximum capacity. The index partition views are redefined onto a new journal during synchronous overflow, but little or no data is copied off of the old journal.

AsynchronousOverflow

public static final EventType AsynchronousOverflow

Asynchronous overflow migrates data off of the old journal and onto read-optimized index segments and is responsible for running operation which split, join, or move index partitions.

IndexSegmentBuild

public static final EventType IndexSegmentBuild

Operation that builds an index segment. Builds may either be simple (from the BTree on a Journal used to absorb writes for an index partition) or compacting merges (from the full view of the index partition).

IndexSegmentStoreOpenClose

public static final EventType IndexSegmentStoreOpenClose

An IndexSegmentStore open-close event (start is open, end is close).

IndexSegmentOpenClose

public static final EventType IndexSegmentOpenClose

An IndexSegment open-close event (start is open, end is close).

PurgeResources

public static final EventType PurgeResources

Purge resources.

StoreManager.purgeOldResources(long, boolean)

Method Detail

values

public static EventType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (EventType c : EventType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static EventType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
