Support calculating count of unique values using off-heap memory. For variable length types (e.g. `STRING`, `BYTES`), we use murmur3 hash (64 bits by default) to represent the value. The function can take an optional string literal argument to configure the following parameters: - initial capacity of the set for non-dictionary-encoded case: positive int (default 10000) - number of bits for murmur3: 32/64/128 (default 64) Query example: `SELECT DISTINCT_COUNT_OFF_HEAP(stringColumn, 'initialcapacity=10;hashbits=128') FROM testTable` -- This is an automated message from the Apache Git Service.
