creating many records in a single query

[killJoy-03]

I have an API that does multiple tasks in multiple threads. (In a single transaction)

Suppose in a task, it is creating 6000 records in a single query
Format is like
MATCH (a:A)
/// 6000 subqueries for creating

NOTE : And we are consuming all the executed queries even though we do not need them, for immediate commit.

Now, for the above query, it throws Out of Memory Exception. some heap was out of memory.

How do you tackle this.
I solution I can do is run in batches.

Any thing else?
