Kurt Young commented on FLINK-13943: ------------------------------------ +1 to Aljoscha's proposal. Most of the time this feature only used by previewing some small data, transfer by `AccumulatorResult` is not ideal but enough for most cases. > Provide api to convert flink table to java List (e.g. Table#collect) > -------------------------------------------------------------------- > > Key: FLINK-13943 > URL: https://issues.apache.org/jira/browse/FLINK-13943 > Project: Flink > Issue Type: Improvement > Components: Table SQL / API > Reporter: Jeff Zhang > Assignee: Caizhi Weng > Priority: Major > > It would be nice to convert flink table to java List so that I can do other > data manipulation in client side after execution flink job. For flink > planner, I can convert flink table to DataSet and use DataSet#collect, but > for blink planner, there's no such api. > EDIT from FLINK-14807: > Currently, it is very unconvinient for user to fetch data of flink job unless > specify sink expclitly and then fetch data from this sink via its api (e.g. > write to hdfs sink, then read data from hdfs). However, most of time user > just want to get the data and do whatever processing he want. So it is very > necessary for flink to provide api Table#collect for this purpose. > Other apis such as Table#head, Table#print is also helpful. -- This message was sent by Atlassian Jira (v8.3.4#803005)
