Fabian Hueske resolved FLINK-846. --------------------------------- Resolution: Implemented Implemented in de8e066ccbd0a31e5746bc0bee524a48bba3a552 > Semantic Annotations - Inconsistencies > -------------------------------------- > > Key: FLINK-846 > URL: https://issues.apache.org/jira/browse/FLINK-846 > Project: Flink > Issue Type: Sub-task > Reporter: GitHub Import > Assignee: Fabian Hueske > Labels: github-import > Fix For: pre-apache > > > This is basically a thread for discussion. There are still a few > inconsistencies in the semantic annotations. The following examples > illustrate that: > _Constant fields_: > `"1 -> 0,1" "3->4"` means field 1 is copied unmodified to 0 and 1, while 3 > becomes 4. > `"1 ->0,1 ; 3->4"` means the same thing, expressed in a single string > (semicolon is the delimiter between statements about fields). > `"1 , 3"` means that 1 and 3 remain constant as 1 and 3. Note that comma is > the delimiter here. > _Read Fields_: > `"0 , 2"` means that fields 0 and 2 are read. Note that here, the delimiter > is the comma, like with the standalone constant fields, unlike the constant > fields with arrow notation. > I find that a bit inconsistent, especially the mixed use of comma and > semicolon for the constant fields. > - Do we want to keep it that way? > - Or use the semicolon for the standalone constant fields and read fields? > - Or use the comma in the constant fields (finding an alternative delimiter > for the right hand side of the arrow? > ---------------- Imported from GitHub ---------------- > Url: https://github.com/stratosphere/stratosphere/issues/846 > Created by: [StephanEwen|https://github.com/StephanEwen] > Labels: > Created at: Wed May 21 20:54:26 CEST 2014 > State: open -- This message was sent by Atlassian JIRA (v6.3.4#6332)
