Interface TrackingConstants

public interface TrackingConstants

Encapsulates constants associated with behavior tracking. All classes in the tracking service should use these constants to avoid typos, conflicting names, etc.

Field Summary

static int	DEFAULT_BUFFER_SIZE The default size of the events buffer.
static String	DEFAULT_DATA_SOURCE_NAME The default connection pool name
static int	DEFAULT_FORCE_FLUSH_INTERVAL Default maximum age of an event in the buffer is 120 seconds.
static int	DEFAULT_TIME_INTERVAL The default time interval, in seconds, at which the events buffer will be checked to see if it needs to be persisted to the database.
static int	MAX_BUFFER_SIZE The maximum size of the events buffer.
static int	MAX_FORCE_FLUSH_INTERVAL Maximum allowable age of an event in the buffer, in seconds.
static int	MAX_TIME_INTERVAL Maximum time, in seconds, to check to see if events in the buffer must be persisted to the database.
static int	MIN_BUFFER_SIZE The minumum size of the events buffer.
static int	MIN_TIME_INTERVAL Minimum time, in seconds, to check to see if events in the buffer must be persisted to the database.

Field Detail

DEFAULT_FORCE_FLUSH_INTERVAL

static final int DEFAULT_FORCE_FLUSH_INTERVAL

Default maximum age of an event in the buffer is 120 seconds. This means that events will not stay in the buffer for more than 120 seconds before being persisted to the database.

Constants Summary

MAX_FORCE_FLUSH_INTERVAL

static final int MAX_FORCE_FLUSH_INTERVAL

Maximum allowable age of an event in the buffer, in seconds. Translates to 5 minutes.

Constants Summary

DEFAULT_TIME_INTERVAL

static final int DEFAULT_TIME_INTERVAL

The default time interval, in seconds, at which the events buffer will be checked to see if it needs to be persisted to the database. There are two conditions that will trigger the persistence of the buffer: either the max buffer size has been reached, or the max age of an event in the buffer has been exceeded.

Constants Summary

MIN_TIME_INTERVAL

static final int MIN_TIME_INTERVAL

Minimum time, in seconds, to check to see if events in the buffer must be persisted to the database. Setting this value to any less than this might cause performance problems. There are two conditions that will trigger the persistence of the buffer: either the max buffer size has been reached, or the max age of an event in the buffer has been exceeded.

Constants Summary

MAX_TIME_INTERVAL

static final int MAX_TIME_INTERVAL

Maximum time, in seconds, to check to see if events in the buffer must be persisted to the database. Translates to 5 minutes.

Constants Summary

DEFAULT_BUFFER_SIZE

static final int DEFAULT_BUFFER_SIZE

The default size of the events buffer.

See Also

Constants Summary

MIN_BUFFER_SIZE

static final int MIN_BUFFER_SIZE

The minumum size of the events buffer. Using this value means the events will be persisted to the database as soon as they are received.

See Also

Constants Summary

MAX_BUFFER_SIZE

static final int MAX_BUFFER_SIZE

The maximum size of the events buffer.

Constants Summary

DEFAULT_DATA_SOURCE_NAME

static final String DEFAULT_DATA_SOURCE_NAME

The default connection pool name
