[jira] [Comment Edited] (CASSANDRA-15358) Cassandra alpha 4 testing
- Nodes crashing due to bufferpool allocator issue
[ https://issues.apache.org/jira/browse/CASSANDRA-15358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16964055#comment-16964055 ]

------------------------------------------------------------------------
Hello,
I had a similar issue earlier today. It was triggered by a client using a code similar to this one: [https://docs.datastax.com/en/developer/python-driver/3.20/query_paging/#handling-paged-results-with-callbacks] with these changes:
* typo fix ( {{handle_err}} -> {{handle_error}})
* {{"SELECT * FROM users"}} replaced with {{SimpleStatement("SELECT * FROM revision", fetch_size=100)}}
The table I'm querying had ~1 billion keys, and is defined with:
{code:java}
CREATE TYPE IF NOT EXISTS person (
fullname blob,
name blob,
email blob
);
CREATE TYPE IF NOT EXISTS microtimestamp (
seconds bigint,
microseconds int
);
CREATE TYPE IF NOT EXISTS microtimestamp_with_timezone (
timestamp frozen<microtimestamp>,
offset smallint,
negative_utc boolean
);
CREATE TABLE IF NOT EXISTS revision (
id blob PRIMARY KEY,
date microtimestamp_with_timezone,
committer_date microtimestamp_with_timezone,
type ascii,
directory blob,
message blob,
author person,
committer person,
parents frozen<list<blob>>,
synthetic boolean,
metadata text
);
{code}
Cluster was initially created with Cassandra 3.11.4, but was migrated to 4.0-alpha1 a few weeks ago. There are four nodes in my cluster, and no replication.
cassandra.yaml was the same as the one shipped with 4.0-alpha1, except for some paths/IP changes, and these changes:
{code:java}
prepared_statements_cache_size_mb: 10
key_cache_size_in_mb: 10
concurrent_reads: 32
concurrent_writes: 64
concurrent_counter_writes: 32
file_cache_size_in_mb: 512
disk_access_mode: mmap
trickle_fsync: true
enable_user_defined_functions: true{code}
After a restart, I am unable to reproduce the issue, so I cannot tell if the issue was caused by my config.
