Example 1 with MetaRangeImpl

use of org.apache.bookkeeper.stream.storage.impl.metadata.stream.MetaRangeImpl in project bookkeeper by apache.

the class MetaRangeStoreImplTest method verifyGetResponse.

private void verifyGetResponse(GetActiveRangesResponse getResp) throws Exception {
    MetaRangeImpl metaRange = new MetaRangeImpl(this.store, this.scheduler.chooseThread(), StorageContainerPlacementPolicyImpl.of(1024));
    assertNotNull(FutureUtils.result(metaRange.load(streamProps.getStreamId())));
    verifyStreamMetadata(metaRange, streamProps);
    List<RelatedRanges> rangesList = getResp.getRangesList();
    List<Long> currentRanges = metaRange.unsafeGetCurrentRanges();
    assertEquals(currentRanges.size(), rangesList.size());
    for (int i = 0; i < rangesList.size(); i++) {
        RelatedRanges actualRR = rangesList.get(i);
        long expectedRid = currentRanges.get(i);
        RangeMetadata expectedRangeMetadata = metaRange.unsafeGetRanges().get(expectedRid);
        assertNotNull(expectedRangeMetadata);
        assertEquals(Collections.emptyList(), actualRR.getRelatedRangesList());
        assertEquals(expectedRangeMetadata.getProps(), actualRR.getProps());
    }
}

Example 2 with MetaRangeImpl

use of org.apache.bookkeeper.stream.storage.impl.metadata.stream.MetaRangeImpl in project bookkeeper by apache.

the class MetaRangeStoreImpl method getActiveRanges.
