Oct 02, 2025

Workers Analytics Engine Workers

You can now perform more powerful queries directly in Workers Analytics Engine ↗ with a major expansion of our SQL function library.

Workers Analytics Engine allows you to ingest and store high-cardinality data at scale (such as custom analytics) and query your data through a simple SQL API.

Today, we've expanded Workers Analytics Engine's SQL capabilities with several new functions:

New aggregate functions: ↗

• argMin() - Returns the value associated with the minimum in a group
• argMax() - Returns the value associated with the maximum in a group
• topK() - Returns an array of the most frequent values in a group
• topKWeighted() - Returns an array of the most frequent values in a group using weights
• first_value() - Returns the first value in an ordered set of values within a partition
• last_value() - Returns the last value in an ordered set of values within a partition

New bit functions: ↗

• bitAnd() - Returns the bitwise AND of two expressions
• bitCount() - Returns the number of bits set to one in the binary representation of a number
• bitHammingDistance() - Returns the number of bits that differ between two numbers
• bitNot() - Returns a number with all bits flipped
• bitOr() - Returns the inclusive bitwise OR of two expressions
• bitRotateLeft() - Rotates all bits in a number left by specified positions
• bitRotateRight() - Rotates all bits in a number right by specified positions
• bitShiftLeft() - Shifts all bits in a number left by specified positions
• bitShiftRight() - Shifts all bits in a number right by specified positions
• bitTest() - Returns the value of a specific bit in a number
• bitXor() - Returns the bitwise exclusive-or of two expressions

New mathematical functions: ↗

• abs() - Returns the absolute value of a number
• log() - Computes the natural logarithm of a number
• round() - Rounds a number to a specified number of decimal places
• ceil() - Rounds a number up to the nearest integer
• floor() - Rounds a number down to the nearest integer
• pow() - Returns a number raised to the power of another number

New string functions: ↗

• lowerUTF8() - Converts a string to lowercase using UTF-8 encoding
• upperUTF8() - Converts a string to uppercase using UTF-8 encoding

New encoding functions: ↗

• hex() - Converts a number to its hexadecimal representation
• bin() - Converts a string to its binary representation

New type conversion functions: ↗

• toUInt8() - Converts any numeric expression, or expression resulting in a string representation of a decimal, into an unsigned 8 bit integer
