# InterBlockCacheSize set the size (the number of cache items) of interblock cache item
# Each item consumes 128 bytes, so the value should be dividend by 128
# Default cache size is 10mb.
# Ex) 100mb = 10,000,000 / 128 = 78,125
inter-block-cache-size = 78125

# IAVLCacheSize set the cache size (the number of cache items) of the iavl tree.
# Each item size consumes 128 bytes, so the value should be dividend by 128
# Default cache size is 100mb.
# Ex) 100mb = 100,000,000 / 128 = 781,250
