This section contains reference documentation for the DISTINCTCOUNTRAWTHETASKETCH function.
The framework enables set operations over a stream of data, and can also be used for cardinality estimation. Pinot leverages the and its extensions from the library org.apache.datasketches:datasketches-java:1.2.0-incubating
to perform distinct counting as well as evaluating set operations.
DISTINCTCOUNTRAWTHETASKETCH(<thetaSketchColumn>, <thetaSketchParams>, predicate1, predicate2..., postAggregationExpressionToEvaluate) -> HexEncoded
thetaSketchColumn
(required): Name of the column to aggregate on.
thetaSketchParams
(required): Parameters for constructing the intermediate theta-sketches.
Currently, the only supported parameter is nominalEntries
(defaults to 4096).
predicates
(optional)_: _ These are individual predicates of form lhs <op> rhs
which are applied on rows selected by the where
clause. During intermediate sketch aggregation, sketches from the thetaSketchColumn
that satisfies these predicates are unionized individually. For example, all filtered rows that match country=USA
are unionized into a single sketch. Complex predicates that are created by combining (AND/OR) of individual predicates is supported.
postAggregationExpressionToEvaluate
(required): The set operation to perform on the individual intermediate sketches for each of the predicates. Currently supported operations are SET_DIFF, SET_UNION, SET_INTERSECT
, where DIFF requires two arguments and the UNION/INTERSECT allow more than two arguments.
These examples are based on the .
We can also provide predicates and a post aggregation expression to compute more complicated cardinalities:

Converts the value from a column that contains an epoch timestamp into another time unit and buckets based on the given time granularity.
DATETIMECONVERT(columnName, inputFormat, outputFormat, outputGranularity)
inputFormat
and outputFormat
are defined using the following structure:
<time size>:<time unit>:<time format>:<pattern>
where:
time size
- size of the time unit eg: 1, 10
time unit
- DAYS
, HOURS
, MINUTES
, SECONDS
, MILLISECONDS
, MICROSECONDS
, NANOSECONDS
time format
EPOCH
SIMPLE_DATE_FORMAT
pattern - defined in case of SIMPLE_DATE_FORMAT
e.g. yyyy-MM-dd
. A specific timezone can be passed using tz(timezone)
. Timezone can be long or short string format timezone. e.g. Asia/Kolkata
or PDT
granularity
is specified in the format <time size>:<time unit>
.
These examples are based on the .

Goodbye, World
Hello, World
This section contains reference documentation for the regexpReplace function
Find and replace a string or regexp pattern with a target string or regexp pattern. If matchStr is not found, inputStr will be returned. By default, all occurrences of match pattern in the input string will be replaced. Default matching mode is case sensitive.
regexpReplace(inputStr, matchRegexp, replaceRegexp)
regexpReplace(inputStr, matchRegexp, replaceRegexp, matchStartPos)
regexpReplace(inputStr, matchRegexp, replaceRegexp, matchStartPos, occurrence)
regexpReplace(inputStr, matchRegexp, replaceRegexp, matchStartPos, occurrence, flag)
inputStr
The input string or the column name on which regexpReplace function should be applied.
matchRegexp
The regular expression or string used to match against the input string or column value.
replaceRegexp
The regular expression or string to replace if a match is found.
matchStartPos
Index of inputStr from where matching should start. Counting starts and 0. Default value is 0 if not specified.
occurrence
Controls which occurence of the matched pattern must be replaced. Counting starts at 0. Default value is -1 if not specified
flag
Single character flag that controls how the regex finds matches in inputStr. If an incorrect flag is specified, the function applies default case sensitive match. Only one flag can be specified. Supported flags are:
i
-> case insensitive match
In the example below, shows a simple string find and replace example where all occurrences of the matched string o
is replaced with string x
.
fxx
The example below shows how a regexp pattern containing consecutive digits is found and replaced with a simple string bar
.
foobar
The example below shows how a regexp pattern containing consecutive non-digits is found and replaced with a simple string bar
.
bar123
The following example demonstrates how replaceStr
can contain backreferences to substrings captured by the matchStr
regular expression. Backreferences are indicated by $n where n can range from 0-9. In the example below, every character in the input is replaced by the character appended with a space.
f o o
This example shows how regexpReplace can be used to remove extra whitespaces between words in an input string.
Pinot is blazing fast
This example shows the power of backreferencing can be used in regexpReplace to format phone numbers.
1-(123) 456-7898
This example shows how the matchStartPos
parameter can be used. Since the matchStartPos
is set to 4, pattern matching against the inputStr
begins at index 4 there by leading to the string healthy
not being replaced.
healthy, something, something and wise
This example shows how the occurence
parameter can be used. In the example below, the matchStr regular expression matches against three instances in the input - healthy
, wealthy
and stealthy
. As the occurence is specified to 2, the second occurence (counting from zero) stealthy
is replaced with something
healthy, wealthy, something and wise
The example below shows the usage of the flag
parameter. Here the case insensitive flag i
is specified.
something, wealthy, stealthy and wise
The examples below show some sample queries using regexpReplace in there WHERE
clause of a query.
