1GB? 10MB? 1KB?
zNode Limit = 1MB.
This is the default size of a single zNode or key/value pair within ZooKeeper. It should be noted that both the Key and the Value are combined into this equation. ZooKeeper is designed as a high read, high throughput system for small keys. It is not designed as a large data store to hold very large data values. As such this 1MB value is a default config option and can be overridden. It is not advised to do so – but increasing the size a little bit will probably not damage your system (it all depends on your unique access patterns and these changes should be made with care and at your own risk).
