Idea #14374
Updated by Peter Amstutz about 6 years ago
Implemented in controller. # Distribute query to each cluster in the federation. # Collect responses, collate by order and truncate to response item limit # Construct a "page token" which consists of the original filters plus additional information needed to get remaining unseen items on each cluster # Respond with object list and page token # Subsequent requests should only use the page token Query parameters: * enable_multisite_search allow partial results ** true enables multisite search ** true by default? ** provide cluster_id= to search only an individual cluster? * return_partial_results ** when true, if a query to a remote cluster fails, return a response with that cluster stripped out and an additional "warning" field mentioning there was a problem ** when false, if any query to a remote cluster fails, the whole request fails * multisite_search_timeout timeout ** how long to wait for a result from one of the remote clusters Query considerations: * Only order on certain columns? Such as only uuid or modified_at * If "select" is specified and specified, must include "uuid" is missing, must add in uuid for remote queries (needed for paging) and strip it out in the response * Only order on scalar columns. Disambiguate rows with the same value by ordering by uuid. ? * Cannot have "offset" * Must be "count=none" * Must be "distinct=false"
