-------------------------------------
Summary: Impala/HBase recommendations need update
Key: IMPALA-8102
URL: https://issues.apache.org/jira/browse/IMPALA-8102
Project: IMPALA
Issue Type: Documentation
Components: Docs
Reporter: Tim Armstrong
Assignee: Tim Armstrong
https://impala.apache.org/docs/build/html/topics/impala_hbase.html hasn't been
updated for a while. The recommendations are a bit out of date - generally
HBase is not the best format for analytic workloads yet that page seems to
encourage using it.
E.g.
{quote}If you have join queries that do aggregation operations on large fact
tables and join the results against small dimension tables, consider using
Impala for the fact tables and HBase for the dimension tables.{quote}
Assigning to myself to figure out what the best practice is, but I think we
need to include:
* A statement Kudu offers significantly better performance for analytical
workloads with mutable data
* A statement that HDFS tables are also preferable unless data is frequently
mutated
* A pointer to the Kudu docs
