Cannot disable index table

[ivan-tkatchev]

This config

[common]
listen = ":9090"
max-cpu = 8

[clickhouse]
url = "http://192.168.1.1:8123/?readonly=2&database=data"
index-table = ""
data-timeout = "1m0s"
index-timeout = "1m0s"
tagged-table = ""

[[data-table]]
table = "metrics"
reverse = false
rollup-conf = "none"
rollup-default-precision = 60
rollup-default-function = "avg"

[logging]
file = "stdout"
level = "info"

gives an error when graphite-clickhouse tries to select from an empty string:

What is the proper way to disable the index table?

Hi @ivan-tkatchev

Maybe there's some misunderstanding here, but index table is a must for proper functioning of this tool and you can't just disable it. Maybe you can describe your usecase and explain why do you want to remove it?
