Tim Armstrong created IMPALA-7053: ------------------------------------- Summary: Reorganise query options into groups Key: IMPALA-7053 URL: https://issues.apache.org/jira/browse/IMPALA-7053 Project: IMPALA Issue Type: Improvement Components: Backend Reporter: Tim Armstrong Assignee: Tim Armstrong
We have quite a lot of query options now and we're adding more for things like resource limits (e.g. IMPALA-6035). It's getting harder for users to understand the organisation and find relevant query options. We should consider grouping similar query options. E.g. for this set of resource limits, we could reorganise in various ways: * mem_limit -> resources.memory.per_node_limit * buffer_pool_limit -> resources.memory.buffer_pool.per_node_limit * thread_reservation_limit -> resources.threads.per_node_limit * thread_reservation_aggregate_limit -> resources.threads.aggregate_limit * exec_time_limit_s -> resources.wallclock.limit_s We could do the conversion incrementally. It would probably make sense to agree on a top-level organisation up-front. * planner - anything that controls planner decisions like join ordering, etc * scheduler - anything that controls scheduler decisions (admission control could maybe be included here too) * resources - resource management functionality (limits, etc) * session - anything related to session management like timeouts * exec - anything that changes query execution behaviour (e.g. codegen, batch sizes, runtime filters, etc) * Probably a group for anything that changes the semantic behaviour of a query (e.g. decimal_v2, appx_count_distinct, strict_mode, abort_on_error). * A group that controls read and write behaviour of file formats like compression, etc -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
