Method Detail

createNewInstantTime

public static String createNewInstantTime(boolean shouldLock,
                                          TimeGenerator timeGenerator,
                                          long milliseconds)

Returns next instant time in the correct format. Ensures each instant time is at least 1 millisecond apart since we create instant times at millisecond granularity.

Parameters:

shouldLock - Whether the lock should be enabled to get the instant time.

timeGenerator - TimeGenerator used to generate the instant time.

milliseconds - Milliseconds to add to current time while generating the new instant time

parseDateFromInstantTime

public static Date parseDateFromInstantTime(String timestamp)
                                     throws ParseException

Throws:

ParseException

instantTimePlusMillis

public static String instantTimePlusMillis(String timestamp,
                                           long milliseconds)

instantTimeMinusMillis

public static String instantTimeMinusMillis(String timestamp,
                                            long milliseconds)

fixInstantTimeCompatibility

public static String fixInstantTimeCompatibility(String instantTime)

formatDate

public static String formatDate(Date timestamp)

getInstantFromTemporalAccessor

public static String getInstantFromTemporalAccessor(TemporalAccessor temporalAccessor)

getLastInstantTime

public static String getLastInstantTime()

getInstantForDateString

public static String getInstantForDateString(String dateString)

Creates an instant string given a valid date-time string.

Parameters:

dateString - A date-time string in the format yyyy-MM-dd HH:mm:ss[.SSS]

Returns:

A timeline instant

Throws:

ParseException - If we cannot parse the date string

setCommitTimeZone

public static void setCommitTimeZone(HoodieTimelineTimeZone commitTimeZone)

isValidInstantTime

public static boolean isValidInstantTime(String instantTime)
