| 修飾子とタイプ | フィールドと説明 |
|---|---|
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%).

shardAvailable(IndexShard shard)
returns true if shard exists and is availabe for updates
