`static ByteSizeValue`	`INACTIVE_SHARD_INDEXING_BUFFER` Once a shard becomes inactive, we reduce the `IndexWriter` buffer to this value (500 KB) to let active shards use the heap instead.
`static ByteSizeValue`	`INACTIVE_SHARD_TRANSLOG_BUFFER` Once a shard becomes inactive, we reduce the `Translog` buffer to this value (1 KB) to let active shards use the heap instead.
`static String`	`INDEX_BUFFER_SIZE_SETTING` How much heap (% or bytes) we will share across all actively indexing shards on this node (default: 10%).
`static String`	`MAX_INDEX_BUFFER_SIZE_SETTING` Only applies when `indices.memory.index_buffer_size` is a %, to set a ceiling on the actual size in bytes (default: not set).
`static String`	`MAX_SHARD_INDEX_BUFFER_SIZE_SETTING` Sets a ceiling on the per-shard index buffer size (default: 512 MB).
`static String`	`MAX_SHARD_TRANSLOG_BUFFER_SIZE_SETTING` Sets a ceiling on the per-shard translog buffer size (default: 64 KB).
`static String`	`MAX_TRANSLOG_BUFFER_SIZE_SETTING` Only applies when `indices.memory.translog_buffer_size` is a %, to set a ceiling on the actual size in bytes (default: not set).
`static String`	`MIN_INDEX_BUFFER_SIZE_SETTING` Only applies when `indices.memory.index_buffer_size` is a %, to set a floor on the actual size in bytes (default: 48 MB).
`static String`	`MIN_SHARD_INDEX_BUFFER_SIZE_SETTING` Sets a floor on the per-shard index buffer size (default: 4 MB).
`static String`	`MIN_SHARD_TRANSLOG_BUFFER_SIZE_SETTING` Sets a floor on the per-shard translog buffer size (default: 2 KB).
`static String`	`MIN_TRANSLOG_BUFFER_SIZE_SETTING` Only applies when `indices.memory.translog_buffer_size` is a %, to set a floor on the actual size in bytes (default: 256 KB).
`static String`	`SHARD_INACTIVE_INTERVAL_TIME_SETTING` How frequently we check shards to find inactive ones (default: 30 seconds).
`static String`	`SHARD_INACTIVE_TIME_SETTING` If we see no indexing operations after this much time for a given shard, we consider that shard inactive (default: 5 minutes).
`static String`	`TRANSLOG_BUFFER_SIZE_SETTING` How much heap (% or bytes) we will share across all actively indexing shards for the translog buffer (default: 1%).
