Log Context

Log”Opening indices [{}]” classname is MetaDataIndexStateService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

         validateShardLimit(currentState; indices; deprecationLogger);
        if (indicesToOpen.isEmpty()) {
            return currentState;
        }

        logger.info(() -> new ParameterizedMessage("opening indices [{}]";
            String.join(";"; indicesToOpen.stream().map(i -> (CharSequence) i.getIndex().toString())::iterator)));

        final MetaData.Builder metadata = MetaData.builder(currentState.metaData());
        final ClusterBlocks.Builder blocks = ClusterBlocks.builder().blocks(currentState.blocks());
        final Version minIndexCompatibilityVersion = currentState.getNodes().getMaxNodeVersion().minimumIndexCompatibilityVersion();
