Add support for generating ANALYZE TABLE ... COMPUTE STATISTICS statements to the data loading
workflow. This allows for capturing simple table stats such as number of rows, number of
partitions, and table size in bytes. These are stored into a new mysql database with the same
name as the metastore except with a '_Stats' suffix. If using Derby a new database results are
stored in a new derby database.
Moved this out of the data loading framework because it is kind of a special
case. I will consider how we can update the framework to address mixed format
tables.
This change moves (almost) all the functional data loading to the new data
loading framework. This removes the need for the create.sql, load.sql, and
load-raw-data.sql file. Instead we just have the single schema template file:
testdata/datasets/functional/functional_schema_template.sql
This template can be used to generate the schema for all file formats and
compression variations. It also should help make loading data easier. Now you
can run:
bin/load-impala-data.sh "query-test" "exhaustive"
And get all data needed for running the query tests.
This change also includes the initial changes for new dataset/workload directory
structure. The new structure looks like:
testdata/workload <- Will contain query files and test vectors/dimensions
testdata/datasets <- WIll contain the data files and schema templates
Note: This is the first part of the change to this directory structure - it's
not yet complete. # Please enter the commit message for your changes. Lines starting
