Create Index Not Supported
Description
Due to architectural reasons, Snowflake does not support indexes so, SnowConvert will comment out all the code related to the creation of indexes. Snowflake automatically creates micro-partitions for every table that help speed up the performance of DML operations, the user does not have to worry about creating or managing these micro-partitions.
Usually, this is enough to have a very good query performance however, there are ways to improve it by creating data clustering keys. Snowflake's official page provides more information about micro-partitions and data clustering.
Example Code
Input Code (Oracle):

Recommendations
Data clustering might be a way to speed up query performance on tables.
