Search on Flex comes to Redis Cloud Pro: same Search API, a fraction of the RAM | Redis

Introduces 'Search on Flex' for Redis Cloud Pro, enabling Redis Search indexes to utilize Flex tiered storage (RAM and SSD). This reduces the memory footprint of search indexes to roughly 10% of in-memory equivalents, making terabyte-scale search practical. It leverages Query Performance Factor (QPF) to mitigate latency increases from disk reads, targeting a 10x latency increase at 10% RAM cost. The feature maintains the existing Redis Search API and client libraries. It supports HASH, TEXT, TAG, and VECTOR index types, with NUMERIC, GEO, JSON, FT.AGGREGATE, FT.HYBRID, and background indexing planned for future parity.
