#!/bin/ksh
#
# This script is used to correct mistakes made in the database schema.
# It currently just allows you to change either the dataType and/or indexType on properties used by nodes.
#
# NOTE - Titan is not elegant in 0.5.3 about making changes to the schema. Bad properties never
# actually leave the database, they just get renamed and stop getting used. So it is
# really worthwhile to get indexes and dataTypes correct the first time around.
# Note also - This script just makes changes to the schema that is currently live.
# If you were to create a new schema in a brandy-new environment, it would look like
# whatever ex5.json (as of June 2015) told it to look like. So, part of making a
# change to the db schema should Always first be to make the change in ex5.json so that
# future environments will have the change. This script is just to change existing
# instances of the schema since schemaGenerator (as of June 2015) does not update things - it
# just does the initial creation.
#
# Boy, this is getting to be a big comment section...
#
# To use this script, you need to pass four parameters:
# propertyName -- the name of the property that you need to change either the index or dataType on
# targetDataType -- whether it's changing or not, you need to give it: String, Integer, Boolean or Long
# targetIndexInfo -- whether it's changing or not, you need to give it: index, noIndex or uniqueIndex
# preserveDataFlag -- true or false. The only reason I can think of why you'd ever want to
# set this to false would be maybe if you were changing to an incompatible dataType so didn't
# want it to try to use the old data (and fail). But 99% of the time this will just be 'true'.
#
# Ie. schemaMod flavor-id String index true
