Read a multi-object JSON file as the input > format, with one query object per line. Similarly, write results to a > multi-object JSON file, with one prediction result + its original query per > line. > Currently getting bulk predictions from PredictionIO is possible with either: > * a {{pio eval}} script, which will always train a fresh, unvalidated model > before getting predictions > * a custom script that hits the {{queries.json}} HTTP API, which is a serious > bottleneck when requesting hundreds-of-thousands or millions of predictions > Neither of these existing bulk-prediction hacks are adequate for the reasons > mentioned. > It's time for this use-case to be a firstclass command :D > Pull request https://github.com/apache/incubator-predictionio/pull/412 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
