Vladimir Ozerov updated IGNITE-6917: ------------------------------------ Issue Type: New Feature (was: Task) > SQL: implement COP command for efficient data loading > ----------------------------------------------------- > > Key: IGNITE-6917 > URL: https://issues.apache.org/jira/browse/IGNITE-6917 > Project: Ignite > Issue Type: New Feature > Security Level: Public(Viewable by anyone) > Components: sql > Reporter: Vladimir Ozerov > Labels: iep-1 > > Inspired by Postgres [1] > Common use case - bulk data load through JDBC/ODBC interface. Currently it is > only possible to execute single commands one by one. We already can batch > them to improve performance, but there is still big room for improvement. > We should think of a completely new command - {{COPY}}. It will accept a file > (or input stream in general case) on the client side, then transfer data to > the cluster, and then execute update inside the cluster, e.g. through > streamer. > First of all we need to create quick and dirty prototype to assess potential > performance improvement. It speedup is confirmed, we should build base > implementation which will accept only files. But at the same time we should > understand how it will evolve in future: multiple file formats (probably > including Hadoop formarts, e.g. Parquet), escape characters, input streams, > etc.. > [1] https://www.postgresql.org/docs/9.6/static/sql-copy.html -- This message was sent by Atlassian JIRA (v6.4.14#64029)
