Apache IoTDB (incubating) is an effort undergoing incubation at The
Apache Software Foundation (ASF), sponsored by the Apache Incubator.
Incubation is required of all newly accepted projects until a further
review indicates that the infrastructure, communications, and decision
making process have stabilized in a manner consistent with other
successful ASF projects. While incubation status is not necessarily a
reflection of the completeness or stability of the code, it does
indicate that the project has yet to be fully endorsed by the ASF.
