Table 9.25. dsctl Command-line Options
| Option | Description |
|---|---|
-ascmd | Generates the command required to set the datasource to the current position |
Returns the current datasource status and position, returning the information as a JSON string. The example below has been formatted for clarity:
shell> dsctl
[
{
"last_frag" : true,
"applied_latency" : 1,
"extract_timestamp" : "2015-01-21 21:46:57.0",
"eventid" : "mysql-bin.000014:0000000000005645;-1",
"source_id" : "tr-11",
"epoch_number" : 22,
"update_timestamp" : "2015-01-21 21:46:58.0",
"task_id" : 0,
"shard_id" : "tungsten_alpha",
"seqno" : 22,
"fragno" : 0
}
]
When the -ascmd option is used, the
information is output in form of a command:
shell> dsctl get -ascmd
dsctl set -seqno 17 -epoch 11 -event-id "mysql-bin.000082:0000000014031577;-1" -source-id "ubuntu"
If the -reset is used, then the
generated command also includes the option. For example:
shell> dsctl get -ascmd -reset
dsctl set -seqno 17 -epoch 11 -event-id "mysql-bin.000082:0000000014031577;-1" -source-id "ubuntu" -reset
