430d48e is described below
commit 430d48e3fb97ad66905b9fad117fd7de3ad2952e
Author: Neha Pawar <neha.pawa...@gmail.com>
AuthorDate: Fri May 15 15:53:02 2020 -0700
The last of the getTimeFieldSpec calls (#5378)
Removing the last of the getTimeFieldSpec calls.
1. SegmentGeneratorConfig now uses the new getSpecForTimeColumn() call,
which returns a DateTimeFieldSpec. Time column is expected in table config if
it is to be considered when creating segment. (this also sets the stage for
allowing a DateTimeFieldSpec to be a primary time column)
2. Removing TimeFieldSpec special handling from
RealtimeSegmentConverter.getUpdatedSchema. There is no need to remove the
incoming time spec. Neither the recordReader nor the dataSource require the
updated schema. Plus, the record transformer is a pass through.
3. Removing special casing for TimeFieldSpec in
Schema.isBackwardCompatible() method. The for loop for all specs includes time
