When I remove edges or vertices from janusgraph, the size of the table in Hbase does not change

[w924490509]

I use Hbase as the storage backend for janusgraph, and when I delete the edges I see that the size of the Hbase table has not changed even after several hours.
g.E().drop().iterate();
This is my configuration:
gremlin.graph=org.janusgraph.core.JanusGraphFactory storage.backend=hbase storage.hostname=node1,node2,node3 storage.hbase.ext.zookeeper.znode.parent=/hbase storage.hbase.table=GRAPH_ALL_0517 storage.hbase.region-count=60 cache.db-cache = true cache.db-cache-clean-wait = 5 cache.db-cache-time = 10000 cache.db-cache-size = 0.3 cache.tx-cache-size=1000000 cache.tx-dirty-size=1000000 storage.batch-loading=true schema.default=none ids.block-size=50000000 ids.renew-timeout=3600000 ids.wait-time=600 ids.renew-percentage=0.5 id.num-partitions=20 storage.buffer-size=10000 graph.set-vertex-id=true cluster.max-partitions=65535 force-index=true

Things to check:

• did you commit the transaction with the drop() step?
• did you inspect the right table (something with edgestore, JanusGraph has multiple tables)

I have confirmed what you said and there is no problem.
And I found that the number of rows in Hbase had changed, but the disk space was not released.

OK, that makes sense. HBase has an automatic compaction process, so I guess releasing disk space is postponed until the compaction.

It is a compression problem of Hbase. Thanks
