Ferdy Galema closed GORA-33.
----------------------------
Resolution: Duplicate
> Read map entries are all DIRTY by default
> -----------------------------------------
>
> Key: GORA-33
> URL: https://issues.apache.org/jira/browse/GORA-33
> Project: Apache Gora
> Issue Type: Bug
> Components: storage-hbase
> Affects Versions: 0.1-incubating
> Reporter: Yves Langisch
> Fix For: 0.3
>
>
> I'm using the following schema with the hbase module:
> {
> "type": "record",
> "name": "Request",
> "namespace": "ch.test.generated",
> "fields" : [
> {
> "name": "data",
> "type": {
> "type": "map",
> "values": "long"
> }
> }
> ]
> }
> In my map I may have hundreds of entries. Persisting them is fine. Getting
> the row, adding a new map entry and persisting it again seems to be a problem
> though. I can see the additional column in the hbase shell but it looks like
> all columns from the map are written to the row again which is a huge
> overhead every time I add a new entry. After looking through the code I saw
> that all map entries have the DIRTY state just after getting the row. Setting
> the state of all entries to CLEAN just after reading the row and before
> adding the new entry resolved the issue. The default state for all read map
> entries should be CLEAN.
