V3 Multi-Datacenter Replication Reference:
Scheduling Fullsync
The fullsync_interval
parameter can be configured in the riak-repl
section of advanced.config
with either:
- a single integer value representing the duration to wait, in minutes, between fullsyncs, or
- a list of pairs of the form
[{"clustername", time_in_minutes}, {"clustername", time_in_minutes}, ...]
pairs for each sink participating in fullsync replication. Note the commas separating each pair, and[ ]
surrounding the entire list.
Examples
Sharing a fullsync time (in minutes) for all sinks:
{riak_repl, [
% ...
{data_root, "/configured/repl/data/root"},
{fullsync_interval, 90} %% fullsync runs every 90 minutes
% ...
]}
List of multiple sinks with separate times in minutes:
{riak_repl, [
% ...
{data_root, "/configured/repl/data/root"},
% clusters sink_boston + sink_newyork have difference intervals (in minutes)
{fullsync_interval, [
{"sink_boston", 120}, %% fullsync to sink_boston with run every 120 minutes
{"sink_newyork", 90}]} %% fullsync to sink_newyork with run every 90 minutes
]}
Additional Fullsync Stats
Additional fullsync stats per sink have been added in Riak Enterprise.
fullsyncs_completed
— The number of fullsyncs that have been completed to the specified sink cluster.fullsync_start_time
— The time the current fullsink to the specified cluster began.last_fullsync_duration
— The duration (in seconds) of the last completed fullsync.
