Eugene Kirpichov commented on BEAM-1323: ---------------------------------------- Filed https://issues.apache.org/jira/browse/BEAM-2706 for the latter, and I suggest to close the current JIRA unless we have a compelling use case for which generic built-in splitting support in JdbcIO.read() is both practical and easier to use. > Add parallelism/splitting in JdbcIO > ----------------------------------- > > Key: BEAM-1323 > URL: https://issues.apache.org/jira/browse/BEAM-1323 > Project: Beam > Issue Type: Improvement > Components: sdk-java-extensions > Reporter: Jean-Baptiste Onofré > Assignee: Jean-Baptiste Onofré > > Now, the JDBC IO is basically a {{DoFn}} executed with a {{ParDo}}. So, it > means that parallelism is "limited" and executed on one executor. > We can imagine to create several JDBC {{BoundedSource}}s splitting the SQL > query in subset (for instance using row id paging or any "splitting/limit" > we can figure based on the original SQL query) (something similar to what > Sqoop is doing). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
