Subject Using external data source for storing tables
Date Mon, 16 May 2016 09:07:50 GMT
Hi all,

1) We have our own data source where we store tables. This data store is
NoSQL store written in C++ (key-value based). Now we would like to use
these tables with Impala. Can we use external-data-source APIs for this
purpose?

2) I looked at this
<https://github.com/cloudera/Impala/blob/master/testdata/bin/create-data-source-table.sql>
and this
<https://github.com/cloudera/Impala/blob/master/ext-data-source/test/src/main/java/com/cloudera/impala/extdatasource/AllTypesDataSource.java>
but not able to understand how will we create tables in external source. I
am thinking we will need to provide C++ or Java APIs to
create/read/write/query tables which Impala will use, is this correct?

Thanks,
Sachin
