can review sql.
Reuse query another member.
fork can do sql
Presto
9. Pluggable backends
supports a great variety of data sources.
If you are making query runner, variety connect data source.
write by Python.
See.

11. Low Cost
Business intelligence tool is very high cost.
If you use AWS, for small deployments t2.micro should be
enough.
We regist 250 queries, using instance type is m3.medium.
memory size is 3.75GB.
1 CPU.
13. easy update
download.
With deploy runs DB migration.
one command update.

fab -Hredash01 -uubuntu deploy_latest_release
recommended clear cache after upgrade...
14. Caching
Query Results Cache in PostgreSQL.
Do not run unnecessary SQL
See the results and come to the company in morning, not
need wait!
So Google Bigquery is Query pricing, one query results can
share.
18. WE love OSS♥
can read a code.
We can trust a code.
if Well do not know behaviors, read the code.
many contributions on github.
330 closed pull requests.
21. GET parameter
can write sql by mustache template.
select * from user where = {{id}}
http://demo.redash.io/queries/146?p_id=1
