…hput limits rule Add schema-bucket-tablet-count-limits rule sourced from Apache Doris 4.x 'Basic Concepts' doc §6.2 (Empirical Values and Limits): - FE memory: ~100 GB per 10M tablets; single BE < 20k tablets - Write throughput: <128 buckets/partition; concentrate writes on few partitions - Cross-reference existing partition/bucket/tablet-size rules Register the rule in the Bucket Strategy index and bump the rule count 37→38.

What
Adds a new best-practice rule
schema-bucket-tablet-count-limits, sourced from theApache Doris 4.x doc "Basic Concepts — 6.2 Empirical Values and Limits".
Why

choice, but none captured the hard operational limits on tablet count, which
directly drive FE memory and import throughput:
