Examples with TConditionalMutation org.apache.accumulo.core.dataImpl.thrift.TConditionalMutation used on opensource projects

Example 1 with TConditionalMutation

use of org.apache.accumulo.core.dataImpl.thrift.TConditionalMutation in project accumulo by apache.

the class ConditionalWriterImpl method convertMutations.

private void convertMutations(TabletServerMutations<QCMutation> mutations, Map<Long, CMK> cmidToCm, MutableLong cmid, Map<TKeyExtent, List<TConditionalMutation>> tmutations, CompressedIterators compressedIters) {
    mutations.getMutations().forEach((keyExtent, mutationList) -> {
        var tcondMutaions = new ArrayList<TConditionalMutation>();
        for (var cm : mutationList) {
            TMutation tm = cm.toThrift();
            List<TCondition> conditions = convertConditions(cm, compressedIters);
            cmidToCm.put(cmid.longValue(), new CMK(keyExtent, cm));
            TConditionalMutation tcm = new TConditionalMutation(conditions, tm, cmid.longValue());
            cmid.increment();
            tcondMutaions.add(tcm);
        }
        tmutations.put(keyExtent.toThrift(), tcondMutaions);
    });
}

Example 2 with TConditionalMutation

use of org.apache.accumulo.core.dataImpl.thrift.TConditionalMutation in project accumulo by apache.

the class ThriftClientHandler method conditionalUpdate.

@Override
public List<TCMResult> conditionalUpdate(TInfo tinfo, long sessID, Map<TKeyExtent, List<TConditionalMutation>> mutations, List<String> symbols) throws NoSuchScanIDException, TException {
    ConditionalSession cs = (ConditionalSession) server.sessionManager.reserveSession(sessID);

            // Assumption is that the client has timed out and is gone. If that's not the case throw
            // an exception that will cause it to retry.
            log.debug("HoldTimeoutException during conditionalUpdate, reporting no such session");
            throw new NoSuchScanIDException();
        }
    }
    TableId tid = cs.tableId;

        Map<KeyExtent, List<ServerConditionalMutation>> updates = mutations.entrySet().stream().collect(Collectors.toMap(entry -> KeyExtent.fromThrift(entry.getKey()), entry -> entry.getValue().stream().map(ServerConditionalMutation::new).collect(Collectors.toList())));
        // @formatter:on
        for (KeyExtent ke : updates.keySet()) {
            if (!ke.tableId().equals(tid)) {
                throw new IllegalArgumentException("Unexpected table id " + tid + " != " + ke.tableId());
            }
        }
        ArrayList<TCMResult> results = new ArrayList<>();
        Map<KeyExtent, List<ServerConditionalMutation>> deferred = conditionalUpdate(cs, updates, results, symbols);
        while (!deferred.isEmpty()) {
            deferred = conditionalUpdate(cs, deferred, results, symbols);
        }
        return results;
    } catch (IOException ioe) {
        throw new TException(ioe);
    } finally {
