NAME

Elasticsearch::Role::CxnPool - Provides common functionality to the CxnPool implementations

VERSION

version 1.05

DESCRIPTION

See the CxnPool implementations:

CONFIGURATION

These configuration options should not be set by the user but are documented here for completeness.

randomize_cxns

By default, the order of cxns passed to "set_cxns()" is randomized before they are stored. Set randomize_cxns to a false value to disable.

METHODS

cxn_factory()

    $factory = $cxn_pool->cxn_factory

Returns the Elasticsearch::Cxn::Factory object for creating a new $cxn instance.

logger()

    $logger = $cxn_pool->logger

Returns the Elasticsearch::Role::Logger-based object, which defaults to Elasticsearch::Logger::LogAny.

serializer()

    $serializer = $cxn_pool->serializer

Returns the Elasticsearch::Role::Serializer-based object, which defaults to Elasticsearch::Serializer::JSON.

current_cxn_num()

    $num = $cxn_pool->current_cxn_num

Returns the current cxn number, which is an offset into the array of cxns set by "set_cxns()".

cxns()

    \@cxns = $cxn_pool->cxns;

Returns the current list of Elasticsearch::Role::Cxn-based cxn objects as set by "set_cxns()".

seed_nodes()

    \@seed_nodes = $cxn_pool->seed_nodes

Returns the list of nodes originally specified when calling "new()" in Elasticsearch.

next_cxn_num()

    $num = $cxn_pool->next_cxn_num;

Returns the number of the next connection, in round-robin fashion. Updates the "current_cxn_num()".

set_cxns()

    $cxn_pool->set_cxns(@nodes);

Takes a list of nodes, converts them into Elasticsearch::Role::Cxn-based objects and makes them accessible via "cxns()".

request_ok()

    $cxn_pool->request_ok($cxn);

Called when a request by the specified $cxn object has completed successfully. Marks the $cxn as live.

request_failed()

    $should_retry = $cxn_pool->request_failed($cxn,$error);

Called when a request by the specified $cxn object has failed. Returns 1 if the request should be retried or 0 if it shouldn't.

should_retry()

    $bool = $cxn_pool->should_retry($error);

Examines the error to decide whether the request should be retried or not. By default, only "Elasticsearch::Error::Cxn" in Elasticsearch::Error errors are retried.

should_mark_dead()

    $bool = $cxn_pool->should_mark_dead($error);

Examines the error to decide whether the $cxn should be marked as dead or not. By default, only "Elasticsearch::Error::Cxn" in Elasticsearch::Error errors cause a $cxn to be marked as dead.

cxns_str()

    $str = $cxn_pool->cxns_str

Returns all "cxns()" as a string for logging purposes.

cxns_seeds_str()

    $str = $cxn_pool->cxns_seeeds_str

Returns all "cxns()" and "seed_nodes()" as a string for logging purposes.

retries()

    $retries = $cxn_pool->retries

The number of times the current request has been retried.

reset_retries()

    $cxn_pool->reset_retries;

Called at the start of a new request to reset the retries count.
