Method Detail

withQueueSize

public ConcurrentUpdateHttp2SolrClient.Builder withQueueSize(int queueSize)

The maximum number of requests buffered by the SolrClient's internal queue before being processed by background threads.

This value should be carefully paired with the number of queue-consumer threads. A queue with a maximum size set too high may require more memory. A queue with a maximum size set too low may suffer decreased throughput as SolrClient.request(SolrRequest) calls block waiting to add requests to the queue.

If not set, this defaults to 10.

withThreadCount(int)

withThreadCount

public ConcurrentUpdateHttp2SolrClient.Builder withThreadCount(int threadCount)

The maximum number of threads used to empty ConcurrentUpdateHttp2SolrClients queue.

Threads are created when documents are added to the client's internal queue and exit when no updates remain in the queue.

This value should be carefully paired with the maximum queue capacity. A client with too few threads may suffer decreased throughput as the queue fills up and SolrClient.request(SolrRequest) calls block waiting to add requests to the queue.

withExecutorService

public ConcurrentUpdateHttp2SolrClient.Builder withExecutorService(ExecutorService executorService)

Provides the ExecutorService for the created client to use when servicing the update-request queue.

alwaysStreamDeletes

public ConcurrentUpdateHttp2SolrClient.Builder alwaysStreamDeletes()

Configures created clients to always stream delete requests.

Streamed deletes are put into the update-queue and executed like any other update request.

neverStreamDeletes

public ConcurrentUpdateHttp2SolrClient.Builder neverStreamDeletes()

Configures created clients to not stream delete requests.

With this option set when the created ConcurrentUpdateHttp2SolrClient sents a delete request it will first will lock the queue and block until all queued updates have been sent, and then send the delete request.

setPollQueueTime

@Deprecated(since="9.2")
public ConcurrentUpdateHttp2SolrClient.Builder setPollQueueTime(int pollQueueTimeMillis)

Deprecated.

Please use setPollQueueTime(long, TimeUnit)

Parameters:

pollQueueTimeMillis - time for an open connection to wait for updates when the queue is empty.

setPollQueueTime

public ConcurrentUpdateHttp2SolrClient.Builder setPollQueueTime(long pollQueueTime,
                                                                TimeUnit unit)

Parameters:

pollQueueTime - time for an open connection to wait for updates when the queue is empty.

build

public ConcurrentUpdateHttp2SolrClient build()

Create a ConcurrentUpdateHttp2SolrClient based on the provided configuration options.
