A CQL ActivityType driver for http://nosqlbench.io/
There is a newer version: 3.12.99
# You can run this file with this command line to see the values printed to stdout:
# ./ebdse run driver=stdout yaml=bindings/timestamp.yaml cycles=10

# This file demonstrates different types of timestamp recipes
# that you can use with virtdata. (The bindings used in ebdse)

# If you want to control the output, uncomment and edit the statement template below
# and modify the named anchors to suit your output requirements.

#statements:
#  example1: "{epochMillis}\n"

bindings:

# All uncommented lines under this are indented, so they become named bindings below
# the entry above

# Normally, the value that you get with a cycle starts at 0.

 cycleNum: Identity();

# So far, we've only been dealing in milliseconds. This is important to get working
# before adding the next step, converting to a more specific type.
# You can take any millisecond output and add conversion functions as shown below.

# this one converts to a java.util.Time

 randomDateWithinFeb2018: AddHashRange(0,2419200000L); StartingEpochMillis('2018-02-01 05:00:00'); ToDate();

# ToDate(...) supports a few argument forms that you can experiment with.
# ToDate(int) will space the dates apart by this many milliseconds.
# ToDate(int,int) will space the dates apart by some millis and also repeat the value for some number of cycles.

# Alternately, you might want to use a org.joda.time.DateTime instead of a java.util.Time:

 randomJodaDateWithinFeb2018: AddHashRange(0,2419200000L); StartingEpochMillis('2018-02-01 05:00:00'); ToJodaDateTime();

# ToJodaDateTime(...) also supports the space and repeat forms as shown above for ToDate(...)

# You can also have the dates in order, but with some limited out-of-order pertubation.
# In this case, we are swizzling the offset by some pseudo-random amount, up to an hour (in millis)

 randomDateWithinFeb2018Jittery: AddHashRange(0,3600000L); StartingEpochMillis('2018-02-01 05:00:00'); ToDate();

# If you want to have the result be a string-formatted date representation for testing, try this:
# You can use any formatter from here: http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html

 timeuuid_string: AddHashRange(0,2419200000L); StartingEpochMillis('2018-02-01 05:00:00'); StringDateWrapper("yyyy-MM-dd HH:mm:ss.SSS");




# ebdse bundles some specialized mapping functions in addition to those explained above, which
# come with eb. These are shown below.

# You can create a com.datastax.driver.core.LocalDate for use with the java driver.
# This takes as its input, the number of days since the unix epoch.

 localdate: LongToLocalDateDays()

# You can also take the millis from any of the examples above which provide epoch millis,
# and convert the output to a millisecond-stable value, analogous to the CQL functions
# that do the same.

 minUUID: AddHashRange(0,3600000); StartingEpochMillis('2018-02-01 05:00:00'); ToTimeUUIDMin();

 maxUUID: AddHashRange(0,3600000); StartingEpochMillis('2018-02-01 05:00:00'); ToTimeUUIDMax();
