LOG_RETENTION = 10 # Keep 10 Logs

# How many threads use for synchronous methods (services).
# 30 is enough for small installation, for real usage
# it should be slightly more, say 100-300.
THREAD_POOL_SIZE = 300

# RPC call throws TimeoutServiceException once total time since request has been
# placed (time to delivery to client + time for processing on the client)
# crosses _TOTAL (in second).
# _TOTAL reflects the fact that not all transports deliver RPC requests to the clients
# instantly, so request can wait some time in the buffer on server side.
# NOT IMPLEMENTED YET

# ******************** TCP SETTINGS ******************

# ******************** HTTP SETTINGS *****************

# High value leads to higher memory usage (all sessions are stored in memory ATM).
# Low value leads to more frequent session reinitializing (like downloading address history).
HTTP_SESSION_TIMEOUT = 3600 # in seconds

# Maximum number of messages (notifications, responses) waiting to delivery to HTTP Poll clients.
