Field Documentation

pthread_mutex_t as_cluster::batch_init_lock
private

Batch transaction lock.

Definition at line 271 of file as_cluster.h.

uint32_t as_cluster::batch_initialized
private

Batch initialize indicator.

Definition at line 241 of file as_cluster.h.

cf_queue* as_cluster::batch_q
private

Batch process queue.

Definition at line 125 of file as_cluster.h.

pthread_t as_cluster::batch_threads[AS_NUM_BATCH_THREADS]
private

Batch process threads.

Definition at line 283 of file as_cluster.h.

uint32_t as_cluster::conn_queue_size
private

Size of node's synchronous connection pool.

Definition at line 217 of file as_cluster.h.

uint32_t as_cluster::conn_timeout_ms
private

Initial connection timeout in milliseconds.

Definition at line 223 of file as_cluster.h.

as_vector* as_cluster::gc
private

Nodes to be garbage collected.

Definition at line 143 of file as_cluster.h.

as_addr_map* 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 190 of file as_cluster.h.

uint32_t as_cluster::ip_map_size
private

Length of ip_map array.

Definition at line 179 of file as_cluster.h.

uint32_t as_cluster::max_socket_idle
private

Maximum socket idle in seconds.

Definition at line 229 of file as_cluster.h.

cl_partition_id as_cluster::n_partitions
private

Total number of data partitions used by cluster.

Definition at line 259 of file as_cluster.h.

uint32_t as_cluster::node_index
private

Random node index.

Definition at line 235 of file as_cluster.h.

as_nodes* as_cluster::nodes
private

Active nodes in cluster.

Definition at line 113 of file as_cluster.h.

as_partition_tables* as_cluster::partition_tables
private

Hints for best node for a partition.

Definition at line 119 of file as_cluster.h.

char* as_cluster::password
private

Password in hashed format in bytes.

Definition at line 161 of file as_cluster.h.

uint32_t as_cluster::query_initialized
private

Query initialize indicator.

Definition at line 253 of file as_cluster.h.

cf_queue* as_cluster::query_q
private

Query process queue.

Definition at line 137 of file as_cluster.h.

pthread_t as_cluster::query_threads[AS_NUM_QUERY_THREADS]
private

Query process threads.

Definition at line 295 of file as_cluster.h.

Definition at line 289 of file as_cluster.h.

as_seed* as_cluster::seeds
private

Initial seed nodes specified by user.

Definition at line 167 of file as_cluster.h.

uint32_t as_cluster::seeds_size
private

Length of seeds array.

Definition at line 173 of file as_cluster.h.

struct as_shm_info_s* as_cluster::shm_info
private

Shared memory implementation of cluster.

Definition at line 149 of file as_cluster.h.

pthread_cond_t as_cluster::tend_cond
private

Definition at line 205 of file as_cluster.h.

uint32_t as_cluster::tend_interval
private

Milliseconds between cluster tends.

Definition at line 211 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 199 of file as_cluster.h.

pthread_t as_cluster::tend_thread
private

Cluster tend thread.

Definition at line 277 of file as_cluster.h.

char* as_cluster::user
private

User name in UTF-8 encoded bytes.

Definition at line 155 of file as_cluster.h.

volatile bool as_cluster::valid
private

Should continue to tend cluster.

Definition at line 265 of file as_cluster.h.
