Hi, I'm finding a weird behavior when using composite indexes. Say I have nodes :Output uniquely identified by tx_hash and output_index. tx_hash is a hash string of 64 random characters from a hash functionoutput_index is an integer in the close to 0...

Indexing a string property is taking several days and it doesn't seem near to completion

Using neo4j-import tool resulted in "java.io.IOException: Exception in the page eviction thread"

How to use composite keys with neo4j-import

When creating a Node Key constraint does the order of the fields matter?

Composite index way slower than property index on one field, how can that be?
