Change subject: IMPALA-12363: Upgrade RE2 to 2023-03-01 ...................................................................... IMPALA-12363: Upgrade RE2 to 2023-03-01 This bumps the version of re2 to 2023-03-01, which is the last release that doesn't have an Abseil dependency. The toolchain already contains a build of re2 2023-03-01, so there is no need to bump the toolchain version. This has a performance benefit for TPC-H's Q13, which uses this predicate: "o_comment not like '%special%requests%" This like predicate is complicated enough that it doesn't fit the heavily optimized paths that exist for simpler likes. Instead, this gets converted to an RE2 regex. The newer RE2 significantly improves performance of that predicate, and TPC-H Q13 gets ~9% faster.
