------------------------------------
Hi [~jeromatron] ,
I looked into this, and while the driver doesn't directly expose datacenter
names, we can retrieve them using a CQL query. The system keyspace has peer and
local tables, both of which include datacenter information that can be used for
this.
>From what I found, the main need for datacenter autocompletion usually comes
>up during CQL commands like
CREATE KEYSPACE <keyspace_name> WITH replication = {'class':
'NetworkTopologyStrategy',
At this point, when pressing tab, cqlsh just shows dc_name instead of listing
the actual available datacenters. It would be helpful if cqlsh could
autocomplete based on the cluster data.
Let me know what you think. As a beginner level contributor, i could really use
your guidance and insights.
> Tab complete datacenter values in cqlsh

> cqlsh has a number of great tab completions. For example, when creating a
> keyspace it will tab complete the syntax for options and give you options for
> the replication strategy. It doesn't show options for the data centers,
> which would be nice to have. The server has access to the list of data
> centers in the cluster. So there shouldn't be a reason why that couldn't tab
> complete.
