Description

When using BuildSideOuterjoin, will frequently call Bitset.set and get, there will be

Preconditions.checkArgument (index <bitLength && index> = 0,
String.format ("Input Index [% d] is larger than BitSet available size [% d].", Index, bitLength));

Of the check, String.format will lead to a sharp decline performance.
