These functions return a boolean predicate (true/false, displayed as 1/0) but the docs declared the return type as TINYINT. Correct them to BOOLEAN across the en/zh-CN/ja docs (current + version-4.x): - is_ip_address_in_range - is_ipv4_string - is_ipv6_string - is_ipv4_mapped - is_ipv4_compat Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
… with inverted index Add a "best practice" section to the IPV6 data type doc covering how to store a mixed IPv4/IPv6 column as IPv4-mapped IPv6 in a single IPV6 column and filter it through an inverted index: - schema with USING INVERTED index - load-time normalization (Routine Load / Stream Load / INSERT INTO) via COALESCE(ipv4_to_ipv6(to_ipv4_or_null(...)), to_ipv6_or_null(...)) - query rewriting: IPv4 CIDR -> mapped IPv6 CIDR (prefix +96), exact match, allowlist / blocklist forms - index-hit prerequisites, and why CIDR range queries need inverted_index_skip_threshold = 0 (two-sided BKD split bypass) Added across en / zh-CN / ja (current + version-4.x).
