Field Documentation

uint32_t as_cluster::async_conn_count
private

Number of active async pipeline and non-pipeline connections combined.

Definition at line 291 of file as_cluster.h.

uint32_t as_cluster::async_conn_pool
private

Number of async connections in the pools.

Definition at line 297 of file as_cluster.h.

uint32_t as_cluster::async_conn_qs_initial_capacity
private

Initial capacity for asynchronous (non-pipeline) connection pools. There is one pool for each node/event loop combination. This variable is ignored if asynchronous event loops are not created.

Definition at line 264 of file as_cluster.h.

uint32_t as_cluster::async_max_conns_per_node
private

Maximum number of asynchronous (non-pipeline) connections allowed for each node. Async transactions will be rejected if the maximum async node connections would be exceeded. This variable is ignored if asynchronous event loops are not created.

Definition at line 256 of file as_cluster.h.

uint32_t as_cluster::async_pending
private

Number of pending async commands (i.e., commands with an outstanding reply).

Definition at line 285 of file as_cluster.h.

uint32_t as_cluster::conn_queue_size
private

Size of node's synchronous connection pool.

Definition at line 248 of file as_cluster.h.

uint32_t as_cluster::conn_timeout_ms
private

Initial connection timeout in milliseconds.

Definition at line 303 of file as_cluster.h.

as_vector* as_cluster::gc
private

Nodes to be garbage collected.

Definition at line 168 of file as_cluster.h.

as_addr_maps* as_cluster::ip_map
private

A IP translation table is used in cases where different clients use different server IP addresses. This may be necessary when using clients from both inside and outside a local area network. Default is no translation.

The key is the IP address returned from friend info requests to other servers. The value is the real IP address used to connect to the server.

Definition at line 209 of file as_cluster.h.

uint32_t as_cluster::max_socket_idle
private

Maximum socket idle in seconds.

Definition at line 309 of file as_cluster.h.

uint16_t as_cluster::n_partitions
private

Total number of data partitions used by cluster.

Definition at line 321 of file as_cluster.h.

uint32_t as_cluster::node_index
private

Random node index.

Definition at line 315 of file as_cluster.h.

as_nodes* as_cluster::nodes
private

Active nodes in cluster.

Definition at line 156 of file as_cluster.h.

as_partition_tables* as_cluster::partition_tables
private

Hints for best node for a partition.

Definition at line 162 of file as_cluster.h.

char* as_cluster::password
private

Password in hashed format in bytes.

Definition at line 186 of file as_cluster.h.

uint32_t as_cluster::pipe_conn_qs_initial_capacity
private

Initial capacity for pipeline connection pools. There is one pool for each node/event loop combination. This variable is ignored if asynchronous event loops are not created.

Definition at line 279 of file as_cluster.h.

uint32_t as_cluster::pipe_max_conns_per_node
private

Maximum number of pipeline connections allowed for each node. Pipeline transactions will be rejected if the maximum pipeline node connections would be exceeded. This variable is ignored if asynchronous event loops are not created.

Definition at line 272 of file as_cluster.h.

as_seeds* as_cluster::seeds
private

Initial seed nodes specified by user.

Definition at line 192 of file as_cluster.h.

struct as_shm_info_s* as_cluster::shm_info
private

Shared memory implementation of cluster.

Definition at line 174 of file as_cluster.h.

pthread_cond_t as_cluster::tend_cond
private

Tend thread identifier to be used with tend_lock.

Definition at line 236 of file as_cluster.h.

uint32_t as_cluster::tend_interval
private

Milliseconds between cluster tends.

Definition at line 242 of file as_cluster.h.

pthread_mutex_t as_cluster::tend_lock
private

Lock for the tend thread to wait on with the tend interval as timeout. Normally locked, resulting in waiting a full interval between tend iterations. Upon cluster shutdown, unlocked by the main thread, allowing a fast termination of the tend thread.

Definition at line 230 of file as_cluster.h.

pthread_t as_cluster::tend_thread
private

Cluster tend thread.

Definition at line 221 of file as_cluster.h.

as_thread_pool as_cluster::thread_pool
private

Pool of threads used to query server nodes in parallel for batch, scan and query.

Definition at line 215 of file as_cluster.h.

bool as_cluster::use_services_alternate
private

If "services-alternate" should be used instead of "services"

Definition at line 327 of file as_cluster.h.

char* as_cluster::user
private

User name in UTF-8 encoded bytes.

Definition at line 180 of file as_cluster.h.

volatile bool as_cluster::valid
private

Should continue to tend cluster.

Definition at line 333 of file as_cluster.h.

uint32_t as_cluster::version
private

Configuration version. Incremented, when the configuration is changed.

Definition at line 198 of file as_cluster.h.
