flush_writes = true
# Full database files increase by this percentage, defaults to 50.
file_growth_rate = 50
# Block hash table size, defaults to 650000.
block_table_buckets = 650000
# Transaction hash table size, defaults to 110000000.
transaction_table_buckets = 110000000
# Spend hash table size, defaults to 250000000.
spend_table_buckets = 250000000
# History hash table size, defaults to 107000000.
history_table_buckets = 107000000
# The maximum number of entries in the unspent outputs cache, defaults to 0.
cache_capacity = 0
