Support unaligned array join For left ARRAY JOIN, expand to the greatest size. If all sizes are zero, resize to one which is the same as the old behavior, i.e. emptyArrayToSingle For non-left ARRAY JOIN, expand to the greatest size but keep empty if all sizes are zero. 2018-12-12 03:13:02 +00:00			`<test>`
