#!/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 - JanusGraph is not particularly elegant in about making changes to the schema.
# 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 our OXM files told it to look like. So, part of making a
# change to the live db schema should Always first be to make the change in the appropriate
# OXM schema file so that future environments will have the change. This script is
# just to change existing instances of the schema since schemaGenerator does not
# update things - it just does the initial creation.
#
# To use this script, there are 4 required parameters, and one optional:
# 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'.
#
# commitBlockSize -- OPTIONAL -- how many updates to commit at once.
# Default will be used if no value is passed.
#
# Ie. schemaMod flavor-id String index true
# or, schemaMod flavor-id String noIndex true 50000
