/**
* A specialized workload dealing with time series data, i.e. series of discreet
* events associated with timestamps and identifiers. For this workload, identities
* consist of a {@link String} <b>key</b> and a set of {@link String} <b>tag key/value</b>
* pairs.
* <p>
* For example:
* <table border="1">
* <tr><th>Time Series Key</th><th>Tag Keys/Values</th><th>1483228800</th><th>1483228860</th><th>1483228920</th></tr>
* <tr><td>AA</td><td>AA=AA, AB=AA</td><td>42.5</td><td>1.0</td><td>85.9</td></tr>
* <tr><td>AA</td><td>AA=AA, AB=AB</td><td>-9.4</td><td>76.9</td><td>0.18</td></tr>
* <tr><td>AB</td><td>AA=AA, AB=AA</td><td>-93.0</td><td>57.1</td><td>-63.8</td></tr>
* <tr><td>AB</td><td>AA=AA, AB=AB</td><td>7.6</td><td>56.1</td><td>-0.3</td></tr>
* </table>
* <p>
* This table shows four time series with 3 measurements at three different timestamps.
* Keys, tags, timestamps and values (numeric only at this time) are generated by
* this workload. For details on properties and behavior, see the
* {@code workloads/tsworkload_template} file. The Javadocs will focus on implementation
* and how {@link DB} clients can parse the workload.
* <p>
* In order to avoid having existing DB implementations implement a brand new interface
* this workload uses the existing APIs to encode a few special values that can be parsed
* by the client. The special values include the timestamp, numeric value and some
* query (read or scan) parameters. As an example on how to parse the fields, see
* {@link BasicTSDB}.
* <p>
* <b>Timestamps</b>
* <p>
* Timestamps are presented as Unix Epoch values in units of {@link TimeUnit#SECONDS},
* {@link TimeUnit#MILLISECONDS} or {@link TimeUnit#NANOSECONDS} based on the
* {@code timestampunits} property. For calls to {@link DB#insert(String, String, java.util.Map)}
* and {@link DB#update(String, String, java.util.Map)}, the timestamp is added to the
* {@code values} map encoded in a {@link NumericByteIterator} with the key defined
* in the {@code timestampkey} property (defaulting to "YCSBTS"). To pull out the timestamp
* when iterating over the values map, cast the {@link ByteIterator} to a
* {@link NumericByteIterator} and call {@link NumericByteIterator#getLong()}.
* <p>
* Note that for calls to {@link DB#update(String, String, java.util.Map)}, timestamps
* earlier than the timestamp generator's timestamp will be choosen at random to
* mimic a lambda architecture or old job re-reporting some data.
* <p>
* For calls to {@link DB#read(String, String, java.util.Set, java.util.Map)} and
* {@link DB#scan(String, String, int, java.util.Set, Vector)}, timestamps
* are encoded in a {@link StringByteIterator} in a key/value format with the
* {@code tagpairdelimiter} separator. E.g {@code YCSBTS=1483228800}. If {@code querytimespan}
* has been set to a positive value then the value will include a range with the
* starting (oldest) timestamp followed by the {@code querytimespandelimiter} separator
* and the ending (most recent) timestamp. E.g. {@code YCSBTS=1483228800-1483228920}.
* <p>
* For calls to {@link DB#delete(String, String)}, encoding is the same as reads and
* scans but key/value pairs are separated by the {@code deletedelimiter} property value.
* <p>
* By default, the starting timestamp is the current system time without any rounding.
* All timestamps are then offsets from that starting value.
* <p>
* <b>Values</b>
* <p>
* Similar to timestamps, values are encoded in {@link NumericByteIterator}s and stored
* in the values map with the key defined in {@code valuekey} (defaulting to "YCSBV").
* Values can either be 64 bit signed {@link long}s or double precision {@link double}s
* depending on the {@code valuetype} or {@code dataintegrity} properties. When parsing
* out the value, always call {@link NumericByteIterator#isFloatingPoint()} to determine
* whether or not to call {@link NumericByteIterator#getDouble()} (true) or
* {@link NumericByteIterator#getLong()} (false).
* <p>
* When {@code dataintegrity} is set to true, then the value is always set to a
* 64 bit signed integer which is the Java hash code of the concatenation of the
* key and map of values (sorted on the map keys and skipping the timestamp and value
* entries) OR'd with the timestamp of the data point. See
* {@link #validationFunction(String, long, TreeMap)} for the implementation.
* <p>
* <b>Keys and Tags</b>
* <p>
* As mentioned, the workload generates strings for the keys and tags. On initialization
* three string generators are created using the {@link IncrementingPrintableStringGenerator}
* implementation. Then the generators fill three arrays with values based on the
* number of keys, the number of tags and the cardinality of each tag key/value pair.
* This implementation gives us time series like the example table where every string
* starts at something like "AA" (depending on the length of keys, tag keys and tag values)
* and continuing to "ZZ" wherein they rollover back to "AA".
* <p>
* Each time series must have a unique set of tag keys, i.e. the key "AA" cannot appear
* more than once per time series. If the workload is configured for four tags with a
* tag key length of 2, the keys would be "AA", "AB", "AC" and "AD".
* <p>
* Each tag key is then associated with a tag value. Tag values may appear more than once
* in each time series. E.g. time series will usually start with the tags "AA=AA",
* "AB=AA", "AC=AA" and "AD=AA". The {@code tagcardinality} property determines how many
* unique values will be generated per tag key. In the example table above, the
* {@code tagcardinality} property would have been set to {@code 1,2} meaning tag
* key "AA" would always have the tag value "AA" given a cardinality of 1. However
* tag key "AB" would have values "AA" and "AB" due to a cardinality of 2. This
* cardinality map, along with the number of unique time series keys determines how
* many unique time series are generated for the workload. Tag values share a common
* array of generated strings to save on memory.
* <p>
* <b>Operation Order</b>
* <p>
* The default behavior of the workload (for inserts and updates) is to generate a
* value for each time series for a given timestamp before incrementing to the next
* timestamp and writing values. This is an ideal workload and some time series
* databases are designed for this behavior. However in the real-world events will
* arrive grouped close to the current system time with a number of events being
* delayed, hence their timestamps are further in the past. The {@code delayedseries}
* property determines the percentage of time series that are delayed by up to
* {@code delayedintervals} intervals. E.g. setting this value to 0.05 means that
* 5% of the time series will be written with timestamps earlier than the timestamp
* generator's current time.
* </p>
* <b>Reads and Scans</b>
* <p>
* For benchmarking queries, some common tasks implemented by almost every time series
* data base are available and are passed in the fields {@link Set}:
* <p>
* <b>GroupBy</b> - A common operation is to aggregate multiple time series into a
* single time series via common parameters. For example, a user may want to see the
* total network traffic in a data center so they'll issue a SQL query like:
* <code>SELECT value FROM timeseriesdb GROUP BY datacenter ORDER BY SUM(value);</code>
* If the {@code groupbyfunction} has been set to a group by function, then the fields
* will contain a key/value pair with the key set in {@code groupbykey}. E.g.
* {@code YCSBGB=SUM}.
* <p>
* Additionally with grouping enabled, fields on tag keys where group bys should
* occur will only have the key defined and will not have a value or delimiter. E.g.
* if grouping on tag key "AA", the field will contain {@code AA} instead of {@code AA=AB}.
* <p>
* <b>Downsampling</b> - Another common operation is to reduce the resolution of the
* queried time series when fetching a wide time range of data so fewer data points
* are returned. For example, a user may fetch a week of data but if the data is
* recorded on a 1 second interval, that would be over 600k data points so they
* may ask for a 1 hour downsampling (also called bucketing) wherein every hour, all
* of the data points for a "bucket" are aggregated into a single value.
* <p>
* To enable downsampling, the {@code downsamplingfunction} property must be set to
* a supported function such as "SUM" and the {@code downsamplinginterval} must be
* set to a valid time interval with the same units as {@code timestampunits}, e.g.
* "3600" which would create 1 hour buckets if the time units were set to seconds.
* With downsampling, query fields will include a key/value pair with
* {@code downsamplingkey} as the key (defaulting to "YCSBDS") and the value being
* a concatenation of {@code downsamplingfunction} and {@code downsamplinginterval},
* for example {@code YCSBDS=SUM60}.
* <p>
* <b>Timestamps</b> - For every read, a random timestamp is selected from the interval
* set. If {@code querytimespan} has been set to a positive value, then the configured
* query time interval is added to the selected timestamp so the read passes the DB
* a range of times. Note that during the run phase, if no data was previously loaded,
* or if there are more {@code recordcount}s set for the run phase, reads may be sent
* to the DB with timestamps that are beyond the written data time range (or even the
* system clock of the DB).
* <p>
* <b>Deletes</b>
* <p>
* Because the delete API only accepts a single key, a full key and tag key/value
* pair map is flattened into a single string for parsing by the database. Common
* workloads include deleting a single time series (wherein all tag key and values are
* defined), deleting all series containing a tag key and value or deleting all of the
* time series sharing a common time series key.
* <p>
* Right now the workload supports deletes with a key and for time series tag key/value
* pairs or a key with tags and a group by on one or more tags (meaning, delete all of
* the series with any value for the given tag key). The parameters are collapsed into
* a single string delimited with the character in the {@code deletedelimiter} property.
* For example, a delete request may look like: {@code AA:AA=AA:AA=AB} to delete the
* first time series in the table above.
* <p>
* <b>Threads</b>
* <p>
* For a multi-threaded execution, the number of time series keys set via the
* {@code fieldcount} property, must be greater than or equal to the number of
* threads set via {@code threads}. This is due to each thread choosing a subset
* of the total number of time series keys and being responsible for writing values
* for each time series containing those keys at each timestamp. Thus each thread
* will have it's own timestamp generator, incrementing each time every time series
* it is responsible for has had a value written.
* <p>
* Each thread may, however, issue reads and scans for any time series in the
* complete set.
* <p>
* <b>Sparsity</b>
* <p>
* By default, during loads, every time series will have a data point written at every
* time stamp in the interval set. This is common in workloads where a sensor writes
* a value at regular intervals. However some time series are only reported under
* certain conditions.
* <p>
* For example, a counter may track the number of errors over a
* time period for a web service and only report when the value is greater than 1.
* Or a time series may include tags such as a user ID and IP address when a request
* arrives at the web service and only report values when that combination is seen.
* This means the timeseries will <i>not</i> have a value at every timestamp and in
* some cases there may be only a single value!
* <p>
* This workload has a {@code sparsity} parameter that can choose how often a
* time series should record a value. The default value of 0.0 means every series
* will get a value at every timestamp. A value of 0.95 will mean that for each
* series, only 5% of the timestamps in the interval will have a value. The distribution
* of values is random.
* <p>
* <b>Notes/Warnings</b>
* <p>
* <ul>
* <li>Because time series keys and tag key/values are generated and stored in memory,
* be careful of setting the cardinality too high for the JVM's heap.</li>
* <li>When running for data integrity, a number of settings are incompatible and will
* throw errors. Check the error messages for details.</li>
* <li>Databases that support keys only and can't store tags should order and then
* collapse the tag values using a delimiter. For example the series in the example
* table at the top could be written as:
* <ul>
* <li>{@code AA.AA.AA}</li>
* <li>{@code AA.AA.AB}</li>
* <li>{@code AB.AA.AA}</li>
* <li>{@code AB.AA.AB}</li>
* </ul></li>
* </ul>
* <p>
* <b>TODOs</b>
* <p>
* <ul>
* <li>Support random time intervals. E.g. some series write every second, others every
* 60 seconds.</li>
* <li>Support random time series cardinality. Right now every series has the same
* cardinality.</li>
* <li>Truly random timetamps per time series. We could use bitmaps to determine if
* a series has had a value written for a given timestamp. Right now all of the series
* are in sync time-wise.</li>
* <li>Possibly a real-time load where values are written with the current system time.
* It's more of a bulk-loading operation now.</li>
* </ul>

/**
* The core benchmark scenario. Represents a set of clients doing simple CRUD operations. The
* relative proportion of different kinds of operations, and other properties of the workload,
* are controlled by parameters specified at runtime.
* <p>
* Properties to control the client:
* <UL>
* <LI><b>fieldcount</b>: the number of fields in a record (default: 10)
* <LI><b>fieldlength</b>: the size of each field (default: 100)
* <LI><b>minfieldlength</b>: the minimum size of each field (default: 1)
* <LI><b>readallfields</b>: should reads read all fields (true) or just one (false) (default: true)
* <LI><b>writeallfields</b>: should updates and read/modify/writes update all fields (true) or just
* one (false) (default: false)
* <LI><b>readproportion</b>: what proportion of operations should be reads (default: 0.95)
* <LI><b>updateproportion</b>: what proportion of operations should be updates (default: 0.05)
* <LI><b>insertproportion</b>: what proportion of operations should be inserts (default: 0)
* <LI><b>scanproportion</b>: what proportion of operations should be scans (default: 0)
* <LI><b>readmodifywriteproportion</b>: what proportion of operations should be read a record,
* modify it, write it back (default: 0)
* <LI><b>requestdistribution</b>: what distribution should be used to select the records to operate
* on - uniform, zipfian, hotspot, sequential, exponential or latest (default: uniform)
* <LI><b>minscanlength</b>: for scans, what is the minimum number of records to scan (default: 1)
* <LI><b>maxscanlength</b>: for scans, what is the maximum number of records to scan (default: 1000)
* <LI><b>scanlengthdistribution</b>: for scans, what distribution should be used to choose the
* number of records to scan, for each scan, between 1 and maxscanlength (default: uniform)
* <LI><b>insertstart</b>: for parallel loads and runs, defines the starting record for this
* YCSB instance (default: 0)
* <LI><b>insertcount</b>: for parallel loads and runs, defines the number of records for this
* YCSB instance (default: recordcount)
* <LI><b>zeropadding</b>: for generating a record sequence compatible with string sort order by
* 0 padding the record number. Controls the number of 0s to use for padding. (default: 1)
* For example for row 5, with zeropadding=1 you get 'user5' key and with zeropading=8 you get
* 'user00000005' key. In order to see its impact, zeropadding needs to be bigger than number of
* digits in the record number.
* <LI><b>insertorder</b>: should records be inserted in order by key ("ordered"), or in hashed
* order ("hashed") (default: hashed)
* <LI><b>fieldnameprefix</b>: what should be a prefix for field names, the shorter may decrease the
* required storage size (default: "field")
* </ul>

* A generator of a zipfian distribution. It produces a sequence of items, such that some items are more popular than

* of items in the set to draw from, either by specifying an itemcount (so that the sequence is of items from 0 to
* itemcount-1) or by specifying a min and a max (so that the sequence is of items from min to max inclusive). After
* you construct the instance, you can change the number of items by calling nextInt(itemcount) or nextLong(itemcount).
*
* Note that the popular items will be clustered together, e.g. item 0 is the most popular, item 1 the second most
* popular, and so on (or min is the most popular, min+1 the next most popular, etc.) If you don't want this clustering,
* and instead want the popular items scattered throughout the item space, then use ScrambledZipfianGenerator instead.
*
* Be aware: initializing this generator may take a long time if there are lots of items to choose from (e.g. over a
* minute for 100 million objects). This is because certain mathematical values need to be computed to properly
* generate a zipfian skew, and one of those values (zeta) is a sum sequence from 1 to n, where n is the itemcount.
* Note that if you increase the number of items in the set, we can compute a new zeta incrementally, so it should be
