Cache.backOffIfDiskSpoolFull介绍

[英]wait outside of synchronized block so as not to block readers If the disk store spool is full wait a short time to give it a chance to catch up. todo maybe provide a warning if this is continually happening or monitor via JMX
[中]在同步块之外等待，以便在磁盘存储假脱机已满时不阻塞读卡器。请稍等片刻，让它有机会赶上。如果这种情况持续发生，todo可能会提供警告，或者通过JMX进行监视
