Impact of quota violation policy
Quota violation policies can impact live write access, bulk write access, and
read access. You must understand what the quota violation policies mean for your
deployment before you plan and implement it on your system.
Live write access You must understand how a quota violation policy configuration affects your ability to write data to HBase. Bulk Write Access Bulk loading HFiles can be an extremely effective way to increase the overall throughput of ingest into HBase. Quota management when bulk loading is important because large HFiles have the potential to quickly violate a quota. Read access In most cases, quota violation policies can affect the ability to read the data stored in HBase. You must understand how a quota violation policy affects your ability to read the data stored in HBase. Metrics and Insight You can view the quotas and metrics about the quotas in the HBase Master user interface. The list of defined quotas are displayed along with those quotas whose violation policy is being enforced. Examples of overlapping quota policies With the ability to define a quota policy on namespaces and tables, you have to define how the policies are applied. A table quota should take precedence over a namespace quota.
