By default uniqCombined() uses 32-bit hash for all types except String, so this means that you cannot use uniqCombined() with i.e UInt64 and cardinality > UINT_MAX, although you can use uniqCombined(toString()) and this will lead to 64-bit hash, but will not have good performance. So uniqCombined64() had been introduced to fix this. Requires: #7213 |
