Method Detail

ramStoreForPrefix

RamStore ramStoreForPrefix(long prefix)

Returns the RAM store in charge of the supplied key prefix. Called during normal operation to read data from the store and to release tombstone records.

This method is allowed to return null, in which case the GC process will assume that the RAM store in question has been destroyed, but the associated event has not yet reached the GC thread. The GC thread will in that case enter a loop which waits for the said event. If the event never arrives, the loop will be infinite.

Returns the RAM store in charge of the supplied key prefix. Called by the Hot Restart store during hot restart in order to supply data to it.
