BI Benchmark bulk delete causes Segmentation Fault

[mxwli]

Currently, everything in the BI benchmark is done with a scale factor of 1.

In the BI Benchmark, running the delete queries causes a segmentation fault. Currently, there is also an issue with the insert queries that causes the benchmark to not complete. In order to skip the insert queries, replace these lines in benchmark.py:89

insert_nodes = ["Comment", "Forum", "Person", "Post"]
insert_edges = ["Comment_hasCreator_Person", "Comment_hasTag_Tag", "Comment_isLocatedIn_Country", "Comment_replyOf_Comment", "Comment_replyOf_Post", "Forum_containerOf_Post", "Forum_hasMember_Person", "Forum_hasModerator_Person", "Forum_hasTag_Tag", "Person_hasInterest_Tag", "Person_isLocatedIn_City", "Person_knows_Person", "Person_likes_Comment", "Person_likes_Post", "Person_studyAt_University", "Person_workAt_Company", "Post_hasCreator_Person", "Post_hasTag_Tag", "Post_isLocatedIn_Country"]

with

insert_nodes = ["Comment"]
insert_edges = []

and remove --queries in scripts/benchmark.sh

and then run the benchmark as specified in the readme file. Running the delete queries gets a segmentation fault in the first delete, which takes the form

LOAD WITH HEADERS (deletionDate TIMESTAMP, id INT64) FROM $csv_file (header=true, delim='|')
MATCH (:Comment {id: id})<-[:REPLY_OF*0..]-(comment:Comment)
DETACH DELETE comment
RETURN count(*)

Closed because currently it cannot be reproduced. May be reopened once I find out why.
