We also see even experienced users being caught by less obvious LIMIT behavior in multi-node environments where a table has many shards. Sharding allows users to split or replicate their data across multiple instances of ClickHouse. When a query with a LIMIT N clause is sent to a sharded table e.g. via a distributed table, this clause will be propagated down to each shard. Each shard will, in turn, need to collate the top N results, returning them to the coordinating node. This can prove particularly resource-intensive when users run queries that require a full table scan. Typically these are "point lookups" where the query aims to just identify a few rows. While this can be achieved in ClickHouse with careful index design a non-optimized variant, coupled with a LIMIT clause, can prove extremely resource-intensive.
If your national economy depends on oil exports, and the compliance system is preventing those exports, you build a parallel system. Iran began doing so in 2018, after sanctions were reimposed as part of negotiations over its nuclear development. Russia dramatically expanded that system in 2022 as restrictions hit in the wake of its invasion of Ukraine.
