@mreiferson
We use NSQ in production environment and find 64 is not long enough for us, 128 will be good.
Can we make TopicName and ChannelName length configurable with default length 64 ?

[mreiferson]

@yujinqiu we applied a limit here because after a certain length they get unwieldy to display, etc. We think it promotes good naming.

However, there's no technical reason this needs to be 64, so if you are persuasive in your arguments, I suppose we would consider increasing it.

@mreiferson thanks for you reply. In our use case we monitor different domains and domain's path, to separate domains we use domain/path as topic name. sometimes path will reach 64 bytes limit, so we want it to be configurable and use 64 bytes as default for downside compatibility. please consider this feature, or I have to change this value and recompile it.
