Define defaults for the LogRecord batching processor #2954
Description
The default values for the parameters of the LogRecord batching processor are marked TODO.
I propose to adopt the same defaults as the Span batching processor.
maxQueueSize: 2048
scheduledDelayMillis: 5000
exportTimeoutMillis: 30000
maxExportBatchSize: 512
If folks feel defaults should differ between spans and logs, can you suggest any specific investigations that would lead us to a better informed set of defaults?
