Trafodion Local-Lite

This checkout includes a local-lite build and runtime mode for native Trafodion SQL engine development.

local-lite removes Java, Maven, Hadoop, HDFS, HBase, Hive, DCS, REST, TrafCI, and Java client modules from the selected build path. The current supported runtime milestone is sqlci as a local single-process command-line SQL engine for queries that do not require storage services.

Local-lite is not a complete standalone database. It has no local storage engine, no JDBC/ODBC service path, no DCS/REST stack, and no HBase/HDFS/Hive runtime.

Full details are in:

docs/local-lite.md

The original Apache Trafodion project overview is preserved in:

README.trafodion.md

Quick Build

Install native dependencies:

scripts/install-local-lite-deps.sh --dry-run
scripts/install-local-lite-deps.sh -y

Build local-lite:

OMPI_CXX=/usr/bin/g++ make local-lite

Quick SQLCI Run

For the current repository build layout:

export TRAF_HOME=$(pwd)/core/sqf
export TRAF_LOCAL_LITE=1

SQL_LIBS=$(pwd)/core/sql/lib/linux/64bit/debug
SQF_LIBS=$(pwd)/core/sqf/export/lib64d
export LD_LIBRARY_PATH=$SQL_LIBS:$SQF_LIBS:${LD_LIBRARY_PATH:-}

$SQL_LIBS/sqlci

Example:

>>SELECT 1 FROM (VALUES(1)) AS t(x);
>>exit;

Use make all for the normal full Trafodion build.
