GEDS - A Generic Ephemeral Data Store

GEDS is a distributed epehemeral datastore that enables flexible scaling of compute and storage. It uses a centralized namenode to store active objects and transparently integrates into S3-like object-stores.

• Building
• geds_smart_open Python package

Ports

GEDS uses the following default ports (see also src/utility/Ports.h).

• Web / Prometheus: 4380
• Metadata Server: 4381
• GEDS RPC: 4382

Benchmarking

1. Start the metadata server on $HOST:

   $GEDS_INSTALL/bin/metadataserver
   

2. Start the benchmarking server on a separate node

   GEDS_METADATASERVER_HOST=$HOST
   GEDS_METADATASERVER_PORT=4381
   export GEDS_METADATASERVER=${GEDS_METADATASERVER_HOST}:${GEDS_METADATASERVER_PORT}
   cd $GEDS_INSTALL/python
   python3.9 serve_benchmark.py
   

3. Run the benchmark command:

   GEDS_METADATASERVER_HOST=$HOST
   GEDS_METADATASERVER_PORT=4381
   $GEDS_INSTALL/bin/benchmark_io --address $GEDS_METADATASERVER_HOST --outputFile output.csv
