Cassandra system properties

Set auto_bootstrap to false during the initial set up of a node to override the default setting in the cassandra.yaml file.

Number of processors available to HCD. In a multi-instance deployment, each instance independently assumes that all CPU processors are available to it. Use this setting to specify a smaller set of processors.

Set to the directory location of the cassandra.yaml file.

Set vector_type_allowed to false to override the ability to use vector search as you initially set up HCD.

Overrides the default bootstrapping behavior of consistent range movement. In the case of an unavailable replica, the consistent bootstrap process can fail.

Set to true to disable authentication caches, for example the caches used for credentials, permissions, and roles. This will mean those config options can only be set (persistently) in the cassandra.yaml file and requires a restart for new values to take effect.

Set the policy (REJECT or CAP) for any TTL (time to live) timestamps that exceeds the maximum value supported by the storage engine, 2038-01-19T03:14:06+00:00. The database storage engine can only encode TTL timestamps through January 19 2038 03:14:07 UTC due to the Year 2038 problem.

Set to true to disable dynamic calculation of the page size used when indexing an entire partition during initial index build or a rebuild. Fixes the page size to the default of 10000 rows per page.

Use when HCD is not using virtual nodes (vnodes). Because vnodes automatically select tokens, this property sets the initial partitioner token for the node on the first start up.

Default: true. Set to false to prevent the node from joining a ring on startup.

Set to false to clear all gossip state for the node on restart.

Caps the maximum amount of memory used by bloom filters. A bloom filter is an off-heap structure associated with each SSTable that checks if any data for the requested row exists in the SSTable before doing any disk I/O.

Set to the port number that CQL native transport listens for clients.

Set to the number of seconds to delay the native transport server start up.

Set to the partitioner name.

Default: true. Set to false to disable JBOD SSTable partitioning by token range to multiple data_file_directories.

Set to the listen_address or the broadcast_address when replacing a dead node with a new node. The new node must be in the same state as before bootstrapping, without any data in its data directory.

Set to false to disable a heap histogram dump on an OutOfMemoryError.

Same as -Dcassandra.replace_address but only runs the first time the HCD node boots.

Allows restoring specific tables from an archived commit log.

Set to the number of milliseconds the node waits to hear from other nodes before formally joining the ring.

Sets the SSL port for encrypted communication.

Enables or disables the native transport server. See start_native_transport in cassandra.yaml.

Sets the port for internode communication.

Set to true to enable a tool for testing new compaction and compression strategies. write_survey allows you to experiment with different strategies and benchmark write performance differences without affecting the production workload. See Testing compaction and compression.
