 | ZO_FEATURE_SHARED_MEMTABLE_ENABLED | false | When set to true, it turns on the shared memtable feature and several organizations can use the same in-memory table instead of each organization creating its own. This helps reduce memory use when many organizations send data at the same time. It also works with older non-shared write-ahead log (WAL) files. |

 **When ZO_FEATURE_SHARED_MEMTABLE_ENABLED is true (shared memtable enabled)**:
 <br>
 OpenObserve creates the specified number of shared in-memory tables that all organizations use together. <br> **If the number is higher**: OpenObserve creates more shared tables. Each table holds data from fewer organizations. This can make data writing faster because each table handles less data. However, it also uses more memory. <br>

 |---------------------|---------------|-------------|
 | ZO_DISTINCT_VALUES_INTERVAL | 10s | Controls how often distinct values for a stream are written from memory to disk. Distinct values are automatically collected when data is ingested. Instead of writing every value to disk immediately, the system waits for this interval. This prevents the system from frequently writing very small chunks of data to disk. Example: If the interval is 10 seconds, distinct values ingested within that 10-second window are combined and written once. |
 | ZO_DISTINCT_VALUES_HOURLY | false | Enables additional deduplication at an hourly level. When enabled, distinct values that repeat within the same hour are merged again, and the system logs a count instead of storing duplicate entries. The collected distinct values are stored in a special stream named distinct_values. Example: Suppose request IDs 123 appear multiple times in one hour. Instead of separate entries, they are merged into one record like: request_id: 123, count: 3  |
