Method Detail

getMaxTotalRam

long getMaxTotalRam()

Return the total amount, in bytes, of RAM that will be used for the Journal.

Returns:

the maximum number of bytes that will be allocated for Journal storage

isNioRam

boolean isNioRam()

Return if the journal will use off-heap buffers (NIO RAM) instead of on-heap buffers (byte arrays).

Returns:

true if the journal is configured to use NIO "direct buffer" RAM

getMaxPoolSize

long getMaxPoolSize()

Return the maximum size (in bytes) of the buffers that can be held by the pool. This is not a limit of how many buffers can be allocated, since some may be in use at any time, but rather how many will be held by the pool (i.e. recycled) as they are released.

Returns:

the maximum size in bytes of all of the buffers that the buffer pool can hold onto
