We are planning to implement an indices on ES 7.x. Is there a way we can keep the indices on memory instead of disk? The total size of the indices will be 150 GB and shared across multiple data nodes. ---

Only if you create an on-memory "disk" that's handled by the OS. There's nothing in Elasticsearch that can do this for you. ---
