Class: BigMap<K, V>
Defined in: packages/core-utils/src/big-map.ts:7
Avoid v8 maximum size for Map by spreading the cache across multiple Maps. This class has the same API as Map but minus more differences in ->set and ->forEach

maxMapSize | readonly | number | - | packages/core-utils/src/big-map.ts:14 |
DEFAULT_MAX_SIZE | static | number | In some cache settings key evictions may not be able to keep up with the addition of new keys, setting the max size at 8.7M keys solves this issue | packages/core-utils/src/big-map.ts:12 |
