Performance issue if a changeset contain a single insert statement with multiple values.

I am currently on liquibase version 3.5.3. I have a .sql file with a changeset that contains a single “insert into table” statement with multiple values. i have observed that insert statements with multiple values work fine if they are not too large. but in my case i have a insert query inserting 6000 rows (apx. 700000 characters long query) within the single statement. like given below 

liquibase.util.StringUtils.processMutliLineSQL(String, boolean, boolean, String)
For now i had to split my insert statements to accomodate not more than 200000 characters in a single sql query. but this could again be a problem for me in future.
