System keyspaces and tables

local

key, bootstrapped, broadcast_address, cluster_name, cql_version, data_center, dse_version, gossip_generation, graph, host_id, jmx_port, listen_address, native_protocol_version, native_transport_address, native_transport_port, native_transport_port_ssl, partitioner, rack, release_version, rpc_address, schema_version, server_id, storage_port, storage_port_ssl, tokens, truncated_at, workload, workloads

Information that a node has about itself and a superset of gossip. Gossip is a peer-to-peer communication protocol for exchanging location and state information between nodes.

peers

peer, data_center, dse_version, graph, host_id, jmx_port, native_transport_address, native_transport_port, native_transport_port_ssl, preferred_ip, rack, release_version, rpc_address, schema_version, server_id, storage_port, storage_port_ssl, tokens, workload, workloads

Each node records what other nodes tell it about themselves over the gossip.

size_estimates

keyspace_name, table_name, range_start, range_end, mean_partition_size, partitions_count

Information on partitions.

aggregates

keyspace_name, aggregate_name, argument_types, final_func, initcond, return_type, state_func, state_type

Information about user-defined aggregates.

columns

keyspace_name, table_name, column_name, dropped_time, type

Information about dropped columns.

functions

keyspace_name, function_name, argument_types, argument_names, body, called_on_null_input, language, return_type

Information on user-defined functions.

indexes
