From df972e868031bc62e83a9ba13e89c0e8467f4022 Mon Sep 17 00:00:00 2001 From: Terry Moschou <5567550+tmoschou@users.noreply.github.com> Date: Sun, 2 Aug 2026 17:51:49 +0930 Subject: [PATCH] CASSANDRA-20012: Finalize blob SAI support for the 6.0 target Fix regressions introduced by the cassandra-5.0 -> cassandra-6.0 rebase and address review feedback: * Restore IndexTermType.isEqOnlyType(AbstractType), which the rebase silently dropped. The method is unused in 5.0 but is still called by 6.0 test infrastructure (CreateIndexDDL, SingleNodeSAITestBase), so its removal broke the build. * Fix the sort order of the sai_blob_term_size_* rows in the GuardrailsConfigCommandsTest verbose expected output. * Restore the two trailing blank lines at the end of CHANGES.txt that were accidentally deleted. * Place the CHANGES.txt entry in the middle of the 6.0-alpha2 section rather than the top, which is the most merge-conflict-prone position. * SAI FAQ: note that BLOB support is new in Cassandra 6.0 (was 5.0.7). * Revert the accidental end-of-file newline change in sai-faq.adoc.
