Reproduced In: 3.11.1
> ReadFailure Error -- Large Unbound Query

> Key: CASSANDRA-14235
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14235
> Project: Cassandra
> Issue Type: Bug
> Components: Messaging/Client
> Environment: My instance of Cassandra is a single local node. It was
> installed via a tar file, versus installing it as a service. All settings are
> default.
> I'm operating on a Centos 7 machine (release 7.4.1708)

> Receiving ReadFailure Error when executing 'select' query with cassandra
> python-driver.
> I have a keyspace called "Documents" and a table with two columns, name and
> object. Name is the text datatype and object is the blob datatype. The blob
> objects are pickled python class instances. The description of the
> keyspace/table is as follows:
>
> {code:java}
> CREATE TABLE "Documents".table (
> name text PRIMARY KEY,
> object blob
> ) WITH bloom_filter_fp_chance = 0.01
> AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'} AND comment
> = ''
> AND compaction = {'class':
> 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy',
> 'max_threshold': '32', 'min_threshold': '4'}
> AND compression = {'chunk_length_in_kb': '64', 'class':
> 'org.apache.cassandra.io.compress.LZ4Compressor'}
> AND crc_check_chance = 1.0
> AND dclocal_read_repair_chance = 0.1
> AND default_time_to_live = 0 AND gc_grace_seconds = 864000
> AND max_index_interval = 2048
> AND memtable_flush_period_in_ms = 0 AND min_index_interval = 128
> AND read_repair_chance = 0.0
> AND speculative_retry = '99PERCENTILE';{code}
>
> There are 3509 rows contained within this table and each object is approx.
> 25kb of data. (so I'm estimating ~90Mb of data in the object column.) I'm
> attempting to run a simple line of python cassandra code :
> {code:java}
> rows = session.execute("SELECT name, object FROM table")
> {code}
> and in the log file of cassandra this is what is produced:
> {code:java}

> In addition to my query working in CQLSH, I can also execute the query from
> python on other identical tables. The only difference being they have less
> rows ∴ less data.
> I have attempted to change timeout values in the yaml file to not avail,
> which makes sense because this is not a timeout issue. I have also modified
> the tombstone_failure_threshold variable in the yaml file, again to no avail.
> How can I execute a query on a large dataset without receiving this error. Is
> it possible to set a batch_size variable? Any guidance at this point would be
> helpful.
