Log Context

Log”[{}] creating index; cause [{}]; shards [{}]/[{}]; mappings {}” classname is MetaDataCreateIndexService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
                    MetaData newMetaData = MetaData.builder(currentState.metaData())
                            .put(indexMetaData; false)
                            .build();

                    logger.info("[{}] creating index; cause [{}]; shards [{}]/[{}]; mappings {}"; request.index(); request.cause(); indexMetaData.numberOfShards(); indexMetaData.numberOfReplicas(); mappings.keySet());

                    ClusterBlocks.Builder blocks = ClusterBlocks.builder().blocks(currentState.blocks());
                    if (!request.blocks().isEmpty()) {
                        for (ClusterBlock block : request.blocks()) {
                            blocks.addIndexBlock(request.index(); block);
