`fetch_synapse_connections` is extremely slow when pulling data

[Mohinta2892]

Hi !

I am trying to fetch a large dataset from hemibrain:v1.2.1 using fetch_synapse_connections function.

However, it is super slow and throws timeout issues like below:

failed to execute query: Neo4jError: Neo.ClientError.Transaction.TransactionTimedOut (The transaction has been terminated. Retry your operation in a new transaction, and you should see a successful result. The transaction has not completed within the specified timeout (dbms.transaction.timeout). You may want to retry with a longer timeout. )

I have played with the batch_size in a range 1000-10000. However, nothings solves the around issue.

This was not a problem a few months back.
Any help on how to resolve this will be greatly appreciated!

Best,
Samia
